Liu QZ, Sun NZ. Investigation on the quality of life after anterior minimally invasive total hip arthroplasty: Commentary on recent findings. World J Orthop 2025; 16:105318. [PMID: 40124731 PMCID: PMC11924025 DOI: 10.5312/wjo.v16.i3.105318] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/18/2025] [Revised: 02/23/2025] [Accepted: 02/25/2025] [Indexed: 03/12/2025] Open
Abstract
This editorial critically evaluated the recent study by Ishikura et al, which examined the impact of anterior minimally invasive total hip arthroplasty (MIS-THA) on postoperative quality of life, with a specific focus on the timeline and influencing factors for return to work and resumption of driving. Ishikura et al's research demonstrated that anterior MIS-THA could shorten recovery time, reduce postoperative pain, and significantly enhance patients' quality of life and productivity. Their findings identified occupational type and work intensity as key determinants of postoperative recovery. By synthesizing evidence from multiple studies, this analysis systematically evaluated the clinical advantages of anterior MIS-THA-including reduced soft tissue trauma and accelerated functional recovery-while acknowledging its limitations, such as a steep surgical learning curve and early postoperative complication risks. The discussion emphasized the necessity of designing personalized rehabilitation protocols that accounted for patients' occupational demands. Notably, while current findings primarily derived from retrospective analyses, the article highlighted the need for prospective cohort studies to validate these observations. The commentary also addressed ongoing debates in the field, particularly the elevated complication rates associated with the direct anterior approach compared to posterior techniques, thereby underscoring the critical role of surgeon expertise in optimizing procedural safety. Collectively, this evaluation advanced our understanding of postoperative recovery dynamics in anterior MIS-THA and provides evidence-based insights to refine clinical rehabilitation frameworks.

Abstract
Total hip arthroplasty (THA) is one of the most successful elective operations in orthopedic surgery for improving pain and functional disability in patients with end-stage joint disease. However, dislocation continues to be a troublesome complication after THA, as it is a leading cause of revision and is associated with substantial social, health, and economic costs. It is a relatively rare, usually early occurrence that depends on both the patients' characteristics and the surgical aspects. The most recent and important finding is the special attention to be given preoperatively to spinopelvic mobility, which is closely related to the incidence of dislocation. Consequently, clinical and radiographic assessment of the lumbar spine is mandatory to identify an altered pelvic tilt that could suggest a different positioning of the cup. Lumbar spinal fusion is currently considered a risk factor for dislocation and revision regardless of whether it is performed prior to or after THA. Surgical options for its treatment and prevention include the use of prostheses with large diameter of femoral head size, dual mobility constructs, constrained liners, and modular neck stems.

Abstract
BACKGROUND Reports show a high complication rate when starting with the Direct Anterior Approach (DAA) in a supine position for hip arthroplasty. The DAA with the patient in lateral decubitus position may avoid this problem because it supposedly provides better visibility, especially on the femoral side. However, this approach did show a rather high complication rate during the adoption of the approach at 1 year follow up in our previous report. We were interested what the overall 7 year survival estimate would be and whether improvement could be seen with growing experience. METHODS A cohort of patients undergoing total hip arthroplasty right from the start of applying the DAA in lateral decubitus position was analysed. RESULTS In total 175 hip prostheses (162 patients) were evaluated. The 7-year survival estimate was 95.1%, 95 CI: 91.8-98.4%. In 6 of 8 revisions there was aseptic loosening of the stem. By dividing the cohort into 3 consecutive groups in time we did not see a significantly improving revision rate. CONCLUSIONS In our experience, the adoption of the direct anterior approach in lateral decubitus position caused a relatively low 7-year survival estimate without an apparent decrease with growing experience, however given the low number of cases further research is needed to investigate the long-term risk of adopting a new approach.

Abstract
PURPOSE OF THE STUDY This manuscript aims to introduce our surgical technique, with an emphasis on the latest recommendations. The AMIS technique is discussed in more detail in patients with Class II and Class III obesity. We seek to prove the premise claiming that the anteversion and inclination values observed in this group of patients do not differ signifi cantly from those observed in patients with the recommended BMI index. We will also compare the risk of neurovascular bundle injury and postoperative complication rate regarding the surgical wound. MATERIAL AND METHODS Patients who underwent surgery using the AMIS method in the period between 1/2020 and 4/2023 were assessed retrospectively. The study included 1150 implantations. The entire study population was assessed for neurovascular bundle injury and surgical wound healing complications. For this purpose, the patients were divided into two groups based on the BMI, namely BMI < 35 kg/m2 (n=1042) and BMI > 35 kg/m2 (n=108). In patients with the BMI ≤ 25 kg/m2 (n=280) and BMI ≥ 35 kg/m2 (n=108), the inclination and anteversion values were compared. Standard centered AP view X-rays of their operated joints were assessed. The Liaw's method was used to calculate the anteversion and inclination. RESULTS In group one of patients with BMI ≤ 25 kg/m2 (208 women and 72 men), the arithmetic mean of acetabular anteversion was 25.4° (median 25°) and inclination was 38.3° (median 38°). In group two, which consisted of patients with BMI ≥ 35 kg/m2 (59 women and 49 men), the total arithmetic mean of acetabular anteversion was 25.1° (median 25) and inclination was 37.6° (median 37.5°). The anteversion and inclination were assessed using the Mann-Whitney test for equality of medians. The value of 0.05 was chosen as the level of signifi cance. The resulting p-value was 0.5359 in anteversion and 0.3763 in inclination. Since the p-value of both anteversion and inclination was greater than the chosen level of signifi cance, their medians have not been confi rmed to differ signifi cantly. A total of 6 cases of femoral nerve injury was reported, i.e. 0.5% out of 1150. Therefore, the risk of injury was 0.4% in the group with BMI < 35 kg/m2 (n=1042). On the contrary, in the group of patients with BMI > 35 kg/m2 (n=108), the risk was 2%. No injury to femoral artery was reported. The surgical wound healing complications were seen in a total of 87 cases (7.6%). In the group with BMI < 35 kg/m2 , healing complications of the surgical wound were observed in 7.4% of cases, with the need for revision surgery in 7 patients. In the group with BMI > 35 kg/ m2 , healing complications occurred in 13% of patients and wound revision was necessary in 4 cases. DISCUSSION Our results are consistent with those in the published studies that also show no signifi cant difference in anteversion and inclination of components in the compared groups of obese patients. We also agree with the other authors that the rate of complications regarding surgical wound healing is higher in these patients. The risk of neurovascular bundle injury in this study population is not higher than the standard. CONCLUSIONS The results obtained in our study population show that this method can also be used in patients with higher BMI, with no concern about the implantation of components in malposition or a higher risk of neurovascular injury. Nonetheless, potentially higher risk of surgical wound healing should be considered when this approach is opted for. With the appropriate surgical technique, AMIS is a safe method and, in our view, the fi rst choice especially for obese patients.

The Association between Acetabulum Fractures and Subsequent Coxarthrosis in a Cohort of 77 Patients-A Retrospective Analysis of Predictors for Secondary Hip Osteoarthritis. J Clin Med 2023; 12:6553. [PMID: 37892691 PMCID: PMC10607311 DOI: 10.3390/jcm12206553] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2023] [Revised: 10/12/2023] [Accepted: 10/14/2023] [Indexed: 10/29/2023] Open
Abstract
OBJECTIVE the aim of this study was to document the occurrence of THA after acetabulum surgery and examine the factors that predict its occurrence. METHODS This study included 77 consecutive patients who were admitted for acetabulum fracture surgery between 2012 and 2019. The inclusion criteria were acetabular fractures and indications for operative management. The exclusion criteria were acetabular fractures treated non-operatively, fractures requiring primary THA, and periprosthetic acetabular fractures. Data concerning demographics, date of injury, date of surgery, surgical approach, stabilization, and further reconstructive surgery were collected retrospectively. The number of patients who underwent THA and their risk factors were recorded. The minimum follow-up for each patient was 2 years of observation. A total of 77 patients with a mean age of 53 years were included. RESULTS At a mean follow-up of 2 years, THA was performed in 16 (20.8%) patients due to post-traumatic arthritis. An analysis of the surgical approaches showed that the Kocher-Langenbeck approach increased the risk of THA nearly 12 times compared with the ilioinguinal approach (p = 0.016). Furthermore, the duration of the waiting period for surgery significantly impacted the occurrence of THA, with each additional day leading to an 89% increase in the risk of prosthesis usage (p = 0.001). CONCLUSIONS This study suggests that acetabular fractures may lead to post-traumatic hip osteoarthritis. The surgical approach and the waiting time for surgery are potential factors that may predict secondary hip osteoarthritis and the need for subsequent THA. However, further investigations should be performed to establish predictors for secondary hip osteoarthritis, and especially to determine the impact of the surgical approach.

MEDICINA (KAUNAS, LITHUANIA) 2023; 59:1390. [PMID: 37629680 PMCID: PMC10456498 DOI: 10.3390/medicina59081390] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/10/2023] [Revised: 07/23/2023] [Accepted: 07/27/2023] [Indexed: 08/27/2023]
Abstract
Background and Objectives: The anterior-based muscle-sparing (ABMS) approach, which utilizes the interval between the tensor fasciae latae posteriorly, offers several advantages, such as the reduced risk of nerve injury and the freedom to choose various implants. Herein, we aimed to compare the outcome of ABMS to the direct anterior (DA) approach using pairwise meta-analysis techniques. Materials and Methods: A systematic search of the MEDLINE (PUBMED), Embase, and Cochrane Library databases was performed for studies published up to 7 June 2023, which compared the ABMS approach with the DA approach for hip arthroplasty. We compared (1) perioperative outcomes (operation time, visual analog scale (VAS) score, total opioid consumption, length of hospital stay (LOS), and the number of patients discharged to their homes); (2) postoperative complications (neuropraxia/nerve injury, dislocation, surgical site infection, intraoperative fracture, and reoperation rate); and (3) implant position (cup inclination, cup anteversion, and stem alignment). Results: Ten studies were eligible for meta-analysis, including 1737 patients who underwent hip arthroplasty with the ABMS approach and 1979 with the DA approach. The pooled analysis showed no differences in all outcome variables, including perioperative outcomes, postoperative complications, and the implant position between the two surgical approaches. Conclusions: In current meta-analysis, the ABMS approach demonstrated comparable results to the conventional DA approach in terms of both clinical and radiologic outcomes as well as postoperative complications. Furthermore, the ABMS approach has the advantage of a broader indication and fewer limitations in terms of the surgical position compared to the DA approach. Therefore, the ABMS approach can be even more beneficial as an option within MSA, surpassing the utility of the DA approach.

Abstract
There are three traditional surgical approaches to hemiarthroplasty (HA) for femoral neck fractures, respectively, the anterior approach (AA), the lateral approach (LA) and the posterior approach (PA). However, the optimum approach is still controversial, the purpose of this meta-analysis is to identify the merits and demerits of all three approaches. All clinical published studies in PubMed, Web of Science, Embase, and the Cochrane Library from January 2000 to April 2022 were searched which compared different surgical approaches and covered surgery-related outcomes and frequent complications. Five randomized controlled trials and 26 cohort studies for a total of 31 clinical trials were included in the meta-analysis. The dislocation of PA was significantly higher than LA (OR: 3.00 95% CI: 2.25-4.01 I 2 = 27% P < 0.00001) and AA (OR: 6.61 95% CI: 2.28-19.13 I 2 = 0% P = 0.0005); PA was substantially more than LA in terms of risk of postoperative reoperation (P < 0.05); meanwhile, AA has markedly shorter hospital length of stays than LA. The remaining items showed no significant differences in the results.The results of this meta-analysis demonstrated that the risk of PA dislocation and reoperation is higher with hemiarthroplasty, and AA has markedly shorter hospital length of stays than LA.

Abstract
Abstract
Background
Total hip arthroplasty (THA) is very effective in alleviating pain, but functional deficits persist up to a year following surgery. Regardless of standard physiotherapy programs, significant additional muscular atrophy and weakness occur. Deficits in strength have serious adverse consequences for these patients with respect to physical function, the maintenance of independence, and the requirement for revision surgery. Progressive resistance training in rehabilitation following THA has been shown to significantly enhance muscle strength and function. The fundamental principle is to progressively overload the exercised muscle as it becomes stronger. Different strength training protocols have been used at different times in the postoperative phase, in group or individual practices, with major differences being in center-based and home-based programs with or without supervision. The primary objective of our study is to evaluate whether an early postoperative home-based strength training protocol can improve patient functional outcomes at 3 months and 1 year following surgery. Secondary objectives are the feasibility of the presented protocol for all elective THA patients and its safety.
Methods/design
This study is a prospective multicenter randomized clinical trial to be conducted in the orthopedic departments of two Slovenian hospitals. In each hospital, 124 patients aged 60 or older with unilateral osteoarthritis, an ASA score between 1 and 3, a signed informed consent form, and no terminal illness disabling rehabilitation participation will be randomly assigned to the intervention or control group. THA with an anterior approach will be performed. All patients will receive current standard physiotherapy during hospitalization. Patients in the intervention group will also learn strength and sensory-motor training exercises. Upon discharge, all will receive USB drives with exercise videos, written exercise instructions, and a training diary. Physiotherapists will perform the assessments (physical tests and the maximal voluntary isometric contraction assessment), and patients will fill out outcome assessment questionnaires (the Harris Hip Score and 36-Item Short Form Health Survey) at baseline and 1, 3, and 12 months after surgery.
Discussion
The main purpose of our study is to design a new standardized rehabilitation protocol with videos that will be effective, safe, and accessible to all Slovenian THA patients.

Abstract
A direct anterior approach (DAA) is a technique practiced by arthroplasty surgeons that can be technically challenging, most notably for inexperienced surgeons. The lateral femoral circumflex artery (LFCA) is a branch of the femoral artery that crosses the surgical field during DAA and is an important landmark for superficial surgical dissection. If the vessel is not identified, significant bleeding may occur, and visualization may be impaired. This study aimed to develop a reliable method to identify and ligate the LFCA with minimal bleeding. First, a retrospective review was performed on a series of patients who underwent primary DAA total hip arthroplasty. Epidemiologic and intraoperative radiologic information was collected to determine the 2-dimensional location of the LFCA as it coursed through the surgical interval. Second, a series of computed tomography (CT) angiograms were compared to validate the intraoperative anatomic findings. In this study, 108 patients were evaluated fluoroscopically and 100 CT angiograms were obtained, for 208 total patients. The distance of the LFCA from the lesser trochanter with standard fluoroscopy (LT/TD) was 0.600 vs 0.438 on CT angiogram. Mean offset from midline (offset/femur diameter) was 0.166 lateral to midline vs 0.36 medial to midline. Median value of offset was 0 vs 0.411-representing a position on the anatomic axis of the femur. This study confirmed that the LFCA is found approximately one-third to two-thirds of the way between the lesser and greater trochanters along the anatomic axis of the femur for most patients. Surgeons who are new to DAA can use the LFCA as a reliable landmark to confirm the correct interval. [Orthopedics. 2022;45(5):262-268.].

[PMID: 36013024 PMCID: PMC9410486 DOI: 10.3390/jcm11164785] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/14/2022] [Revised: 08/09/2022] [Accepted: 08/12/2022] [Indexed: 01/08/2023] Open
Abstract
Background: During the COVID-19 emergency, the incidence of fragility fractures in elderly patients remained unchanged. The management of these patients requires a multidisciplinary approach. The study aimed to assess the best surgical approach to treat COVID-19 patients with femoral neck fracture undergoing hemiarthroplasty (HA), comparing direct lateral (DL) versus direct anterior approach (DAA). Methods: A single-center, observational retrospective study including 50 patients affected by COVID-19 infection (30 males, 20 females) who underwent HA between April 2020 to April 2021 was performed. The patients were allocated into two groups according to the surgical approach used: lateral approach and anterior approach. For each patient, the data were recorded: age, sex, BMI, comorbidity, oxygen saturation (SpO2), fraction of the inspired oxygen (FiO2), type of ventilation invasive or non-invasive, HHb, P/F ratio (PaO2/FiO2), hemoglobin level the day of surgery and 1 day post operative, surgical time, Nottingham Hip Fractures Score (NHFS) and American Society of Anesthesiologists Score (ASA). The patients were observed from one hour before surgery until 48 h post-surgery of follow-up. The patients were stratified into five groups according to Alhazzani scores. A non-COVID-19 group of patients, as the control, was finally introduced. Results: A lateral position led to a better level of oxygenation (p < 0.01), compared to the supine anterior approach. We observed a better post-operative P/F ratio and a reduced need for invasive ventilation in patients lying in the lateral position. A statistically significant reduction in the surgical time emerged in patients treated with DAA (p < 0.01). Patients within the DAA group had a significantly lower blood loss compared to direct lateral approach. Conclusions: DL approach with lateral decubitus seems to preserved respiratory function in HA surgery. Thus, the lateral position may be associated with beneficial effects on gas exchange.

Direct Anterior Approach for Primary Total Hip Arthroplasty Lowers the Risk of Dislocation Compared to the Posterior Approach: A Single Institution Experience. J Arthroplasty 2022; 37:495-500. [PMID: 34774686 DOI: 10.1016/j.arth.2021.11.011] [Citation(s) in RCA: 34] [Impact Index Per Article: 11.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/01/2021] [Revised: 10/23/2021] [Accepted: 11/03/2021] [Indexed: 02/08/2023] Open
Abstract
BACKGROUND One purported benefit of the direct anterior approach (DAA) for total hip arthroplasty (THA) is a lower rate of postoperative dislocation. METHODS An institutional database was used to identify 8840 primary THAs performed from 2003 to 2020 including 5065 (57%) performed using the DAA and 3775 (43%) performed via the posterior approach (PA). Direction and mechanism of dislocation were determined from chart review. Outcomes were compared using Kaplan-Meier survivorship with dislocation as the endpoint and a Cox multivariate regression was used to investigate factors associated with dislocation. The mean follow-up was 1.7 ± 2.0 years for the DAA and 3.1 ± 3.3 years for the PA. RESULTS The 0.5% (26/5065) incidence of dislocation among DAA hips was significantly less than the 3.3% (126/3775) among PA cases (P < .001). The majority of dislocations were posterior (DAA 57%, PA 79%) and occurred during activities of daily living (DAA 82%, PA 77%). Five-year survivorship was significantly higher for the DAA group compared to the PA group (99.1% vs 95.4%, P < .001). Dislocation risk was 4.9 times higher for the PA compared to the DAA (hazard ratio = 4.9, 95% confidence interval = 3.2-7.5, P < .001). Increasing head diameter reduced the risk (hazard ratio = 0.70, 95% confidence interval = 0.57-0.86, P < .001). The 0.2% incidence (10/5065) of revision for instability among the DAA group was significantly lower than the 1.1% (43/3775) rate for the PA group (P < .001). CONCLUSION Compared to primary THAs performed with the PA, DAA cases had a lower risk of dislocation, higher survivorship with dislocation as an endpoint, and a lower risk of revision for instability in this single institution cohort.

Abstract
INTRODUCTION An increased risk of early femoral component loosening has been reported using the direct anterior approach (DAA) compared with other common surgical approaches. However, long-term data are scarce. The purpose of this study is: (1) to determine the incidence of early femoral loosening in a high volume, single surgeon's practice utilising the DAA approach; and (2) to examine the effect of stem design and type of coating on aseptic loosening in the early and mid-term postoperative period. METHODS A retrospective review of 1650 consecutive patients (1800 hips) who underwent total hip arthroplasty (THA) using the DAA between August 2011 and December 2017 was conducted at our institution. 3 types of uncemented femoral stems (Quadra-S, Avenir, TwinSys), with similar design, but different coating, were implanted. Patients were evaluated clinically and radiologically at 4 weeks, 3 months, 1 year, and annually thereafter. RESULTS After a mean follow-up of 46.4 months, the total incidence of revision for aseptic loosening was 0.44% (n = 8). All loose stems were Quadra-S, failing to achieve osseointegration, for an overall incidence of 0.96% (p = 0.002). None of the other stems were loose. Radiolucent lines around the proximal stem portion were visible in 75 Quadra-S stems (4.1%) on radiographs taken at 1 year postoperatively and continued to deteriorate at the latest follow-up. CONCLUSIONS In this specific cohort of patients, the increased rate of femoral stem aseptic loosening was implant-related and was attributed only to a specific type of femoral stem (Quadra-S). No relation to other factors was proven suggesting that the surface characteristics of this femoral stem and the lack of bioactive coating are responsible for the observed early femoral failures. These findings should be confirmed by additional registry work and larger population sample sizes are needed to evaluate the prosthesis performance after implantation through the DAA.

The direct anterior approach to the hip: a useful tool in experienced hands or just another approach? ARTHROPLASTY 2022; 4:1.

Abstract
The direct anterior approach (DAA) to the hip was initially described in the nineteenth century and has been used sporadically for total hip arthroplasty (THA). However, recent increased interest in tissue-sparing and small incision arthroplasty has given rise to a sharp increase in the utilization of the DAA. Although some previous studies claimed that this approach results in less muscle damage and pain as well as rapid recovery, a paucity in the literature exists to conclusively support these claims. While the DAA may be comparable to other THA approaches, no evidence to date shows improved long-term outcomes for patients compared to other surgical approaches for THA. However, the advent of new surgical instruments and tables designed specifically for use with the DAA has made the approach more feasible for surgeons. In addition, the capacity to utilize fluoroscopy intraoperatively for component positioning is a valuable asset to the approach and can be of particular benefit for surgeons during their learning curve. An understanding of its limitations and challenges is vital for the safe employment of this technique. This review summarizes the pearls and pitfalls of the DAA for THA in order to improve the understanding of this surgical technique for hip replacement surgeons.

World J Orthop 2021; 12:877-890. [PMID: 34888148 PMCID: PMC8613681 DOI: 10.5312/wjo.v12.i11.877] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/04/2021] [Revised: 06/27/2021] [Accepted: 09/17/2021] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND The increased prevalence of obesity has resulted in orthopedic surgeons being likely to face many patients with a high body mass index (BMI) who warrant total hip arthroplasties (THAs) over the coming years. Studies' findings considered the postoperative clinical, and functional outcomes in these patients are controversial, and selecting the most appropriate surgical approach remains debatable.
AIM To compare pain-levels, functionality, and quality-of-life in obese and nonobese osteoarthritic patients who have undergone primary total hip arthroplasty through either direct-anterior-approach (DAA) or Hardinge-approach.
METHODS One hundred and twenty participants (> 50 years) were divided into four groups according to the surgical approach (DAA or Hardinge) and patients' BMI (nonobese < 30 kg/m2 vs obese ≥ 30 kg/m2). Outcomes were measured preoperatively and postoperatively (6th and 12th week). Pain was measured with Face Pain Scale-Revised (FPS-R). Functionality was measured with Timed Up & Go (TUG) test and Modified Harris Hip Score-Greek version (MHHS-Gr). Quality-of-life was evaluated with the 12-item-International Hip Outcome Tool-Greek version (iHOT12-Gr) (Clinical Trial Identifier: ISRCTN15066737).
RESULTS DAA vs Hardinge: (week 6) DAA-patients showed 12.2% less pain, more functionality (14.8% shorter TUG-performance time, 21.5% higher MHHS-Gr), and 38.16% better quality-of-life (iHOT12-Gr) compared to Hardinge-patients (all P values < 0.001). These differences were further increased on week 12 (all P values ≤ 0.05)]. DAA-obese vs Hardinge–obese: (week 6) DAA-obese patients had less pain, shorter TUG-performance time, better MHHS-Gr and iHOT12-Gr scores than Hardinge-obese (all P values < 0.01). (Week 12) Only the TUG-performance time of DAA-obese was significantly shortened (22.57%, P < 0.001). DAA-nonobese vs DAA-obese: no statistically significant differences were observed comparing the 6th and 12th weeks' outcomes.
CONCLUSION DAA-groups reported less pain, more functionality and better quality-of-life, compared to the Hardinge-groups. The DAA benefited obese and nonobese patients, similarly yet faster, suggesting that it should be the more preferred choice for obese patients, instead of Hardinge. However, more comparative studies with more extended follow-up periods are needed to confirm our results and better evaluate all patients' long-term outcomes.

Abstract
The direct anterior approach (DAA) is an established approach for total hip arthroplasty (THA) but has been sparingly tried for revisions. The purpose of this study was to examine the available literature in order to consolidate information available on revision THA using the DAA. A PubMed, Embase, and Scopus search was performed using relevant keywords. Studies reporting on patients undergoing revision THA using DAA were included for analysis. In a review of the literature, nine studies matched the pre-decided inclusion criteria with 319 hip joints undergoing revision THA. Mean follow-up of all included studies was 34 months. The indications of revision after primary THA in decreasing order were aseptic loosening (53%), prosthetic joint infection (20.7%), peri-prosthetic fracture (16.9%), dislocation (7.2%), psoas impingement (1.9%), polyethylene wear (1.2%), pain (0.6%), and instability (0.3%). Of the 319 revisions evaluated, 107 underwent a stem revision, 142 underwent cup revision, 49 underwent a combined revision, and 21 underwent isolated liner/head change. A statistically significant improvement in functional score (P<0.05) was observed for all studies reporting on functional outcomes. A low complication rate (51/319, 16.0%), which includes dislocation (12), infection (12), loosening of the acetabular shell (5), peri-prosthetic fractures (6), haematoma (4), and transient nerve palsy (6), was reported. Based on available level III-IV evidence, DAA appears to be a reliable alternative for revision of the failed hip arthroplasty with acceptable complication rates. Evidence of a higher quality is needed to further characterize its role in revision scenarios.

Abstract
BACKGROUND In the current literature, there is no consensus on the best surgical approach in hip replacement for femoral neck fractures (FNFs). AIM The aim of this study is to compare the direct anterior approach (DAA) and the direct lateral approach (DLA) in patients treated with bipolar hemiarthroplasty (BHA) and total hip arthroplasty (THA) for FNFs. MATERIALS AND METHODS Patients with displaced FNFs (Garden type III and IV) treated operatively using BHA and THA were enrolled. The surgical approach techniques DAA and DLA are compared. The analysed variables are: mean surgery time, number of blood units transfused perioperatively, percentage of patients transfused, perioperative complications, pain and functional outcomes at 1 and 6 months and mortality at 1, 3 and 12 months. RESULTS Between 2015 and 2017, 37 patients underwent BHA by the DAA and 38 patients underwent BHA by the DLA, 69 patients underwent THA by the DAA and 60 patients underwent THA by the DLA. For THA, the DAA compared to the DLA had a higher mean surgery time (100.8 min vs. 97.7 min), a lower mean number of blood units transfused perioperatively (1.4 U vs. 1.9 U), a significantly lower percentage of patients transfused (53.6% vs. 71.7%), a higher rate of perioperative complications (10.1% vs. 1.6%), a lower pain referred and better functional outcomes in the first 6 postoperative months and a significantly lower mortality rate at 12 months (2.9% vs. 16.7%). For BHA, the advantages of the DAA over DLA are not as significant. CONCLUSIONS The direct anterior approach in THA for FNFs provides significant benefits in the early post-operative period compared to the direct lateral approach in terms of functional recovery, residual pain, blood loss and mortality rate in the elderly active population. LEVEL OF EVIDENCE Level IV, retrospective cohort study.

Abstract
Several surgical methods exist for the treatment of osteochondral lesions of the femoral head. They include osteochondral allograft transfer, femoral osteotomy, microfracture, autologous chondrocyte implantation, and hip arthroplasty. Mosaicplasty is a surgical method in which cylindrical plugs of bone and cartilage are transferred from a donor site to tunnels drilled into the bone and cartilage defects. This paper discusses the use of mosaicplasty by a direct anterior approach without dislocation in the treatment of an acute femoral head osteochondral impaction in a young patient.

Abstract
OBJECTIVES The purpose of the study was to evaluate the efficacy of hemiarthroplasty with minimally invasive direct anterior approach (DAA) for the treatment of femoral neck fracture in elderly patients. We aimed to compare the DAA and the standard anterolateral approach (ALA), assessing multiple peri‑ and post-operative parameters. DESIGN AND SETTING Between December of 2015 and May of 2017, patients operated with medial femoral neck fractures using bipolar hemiarthroplasty with DAA or ALA were evaluated. The volume of bleeding and transfusion, postoperative level of pain, mobilisation and functional outcome were assessed retrospectively. PARTICIPANTS Patients between the age of 75 and 85, suffering Garden Type III Pauwels Type III and Garden Type IV medial femoral neck fractures were entered to the study. Patients had no history of anticoagulant therapy; the operation was performed in the first 48 h. All patients received similar postoperative pain management and physiotherapy. The type of implants was determined by the patients' bone morphology and quality. MAIN OUTCOME MEASURES The outcomes of interest were the level of postoperative pain, blood loss, rate of recovery and physiotherapy, altered gait pattern and accuracy of leg length, related to DAA and ALA techniques. RESULTS The 51 patients operated with DAA showed significantly less pain, based on VAS (visual analogue scale), starting of the first postoperative day. Those patients who were subjected to DAA met with the criteria of hospital discharge 1.68 days earlier, compared to ALA patients. The length of leg was accurately set in 21% of ALA vs 54.9% of DAA patients. On the 12th week follow-up, limping was detected only 5.9% of DAA vs 46% of ALA groups. On the postoperative 2nd and 6th weeks, the HHS (Harris Hip Score) was significantly better in patients with DAA, compared to ALA (77 vs 65 and 91 vs 77, p < .05). CONCLUSION The bipolar hemiarthroplasty with DAA allows earlier mobilisation, reduced postoperative pain and need for rehabilitation with an overall better functional outcome, compared to ALA. DAA is proven a reliable choice for femoral neck fractures, offering good outcome and faster recovery, similarly to total hip arthroplasties with degenerative arthritis.

Abstract
INTRODUCTION Optimal outcomes in total hip arthroplasty (THA) are dependent on appropriate placement of femoral and acetabular components, with technological advances providing a platform for guiding component placement to reduce the risk of malpositioned components during surgery. This study will validate the intraoperative data captured using a handheld imageless THA navigation system against postoperative measurements of acetabular inclination, acetabular version, leg length and femoral offset on CT radiographs. METHODS AND ANALYSIS This is a prospective observational cohort study conducted within a single-centre, single-surgeon private practice. Data will be collected for 35 consecutive patients (>18 years) undergoing elective THA surgery, from the research registry established at the surgeon's practice. The primary outcome is the agreement between intraoperative component positioning data captured by the navigation system compared with postoperative measurements using CT. A total of ten CT scans will be reassessed for interobserver and intraobserver reliability. The influence of patient and surgical factors on the accuracy of component position will also be examined with multivariable linear regression. ETHICS AND DISSEMINATION Ethics approval for this study was provided through a certified ethics committee (Bellberry HREC approval number 2017-07-499). The results of this study will be disseminated through peer-reviewed journals and conference presentations. TRIAL REGISTRATION Australian and New Zealand Clinical Trials Registry (ANZCTR) Trial ID: ACTRN12620000089932.

Intraoperative pelvic movement is associated with the body mass index in patients undergoing total hip arthroplasty in the supine position. J Orthop Sci 2020; 25:446-451. [PMID: 31174965 DOI: 10.1016/j.jos.2019.05.010] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/20/2019] [Revised: 05/07/2019] [Accepted: 05/10/2019] [Indexed: 02/09/2023]
Abstract
BACKGROUNDS There are very few reports on pelvic movement during total hip arthroplasty (THA) in the supine position. We investigated intraoperative pelvic motion in the sagittal and axial planes to determine if preoperative clinical factors, including body mass index (BMI) affect intraoperative pelvic motion. METHODS Fifty-three patients with osteoarthritis undergoing THA in the supine position were included. Clinical factors, such as age, BMI, and pelvic tilt were assessed preoperatively. Intraoperative pelvic motion in the axial and sagittal planes was assessed using a portable navigation system. We assessed the change in pelvic tilt from registration to cup implantation as the pelvic tilt change; positive values indicated anterior pelvic tilt. We measured the values and absolute values of changes in axial rotation from registration to cup implantation to determine the axial rotation angle. The effects of patient factors on pelvic motion (pelvic tilt change and axial rotation angle) were analyzed using a Spearman's correlation analysis. RESULTS Preoperative pelvic tilt was negatively correlated with pelvic tilt change (r = -0.57, p < 0.05) and the absolute axial rotation angle (r = -0.57, p < 0.05). BMI and absolute axial rotation angle were negatively correlated (r = -0.54, p < 0.05). Age was not correlated with change in the pelvic tilt and the axial rotation angle. CONCLUSIONS Preoperative pelvic tilt and BMI are important factors to determine intraoperative pelvic motion in patients who undergo THA in the supine position. This can help surgeons to preoperatively identify patients with a higher risk of intraoperative pelvic motion.

Abstract
BACKGROUND The anterior approach (AA) to total hip arthroplasty (THA) has advantages for patients and healthcare providers. However, some studies have reported high rates of adverse events when introducing AA-THA. This was not consistent with our center's experience, where 4 senior surgeons safely introduced AA-THA into practice. The purpose of this study is to define the adverse event rates associated with the introduction of AA-THA by a group of experienced surgeons at a single tertiary care center and define experiential factors that may modify adverse event rates. METHODS Retrospective review of prospectively collected data for an observational cohort of all patients undergoing a THA between 2006 and 2017 was conducted. Four senior surgeons at a single institution operated on 1087 primary elective hips using AA-THA. RESULTS Between 2006 and 2016, AA-THA rose from 1.5% to 53.2% of annual THA. Adverse events included intraoperative events, early postoperative periprosthetic fractures, dislocation, implant failure, early infection, and wound complications. We observed an overall 90-day adverse event rate of 6.4% (of 1087 hips). The adverse event rate was 41.6% (of 12 hips) in the first 12 months of the study period and 3.6% (of 166 hips) in the final 12 months of the study period reviewed. Sixty hips (5.5%) required a reoperation with or without revision of components, 1 (8.3%) in the first 12 months of the study period and 1 (0.6%) in the final 12 months of the study period. Infection and wound complications were the most common causes of reoperation at 1.8% for all cases (20 hips). Higher rates of adverse events are associated with early procedures (n ≤ 15) for all surgeons but showed no statistically significant impact on 5-year survival rate. CONCLUSION Our experience demonstrates that AA-THA can be introduced into practice with an acceptable adverse event rate when compared with other approaches to THA. As expected the incidence of adverse events is higher in the early part of the learning curve. Surgeon mentoring in the first 20 cases should be considered to minimize risk of adverse events. LEVEL OF EVIDENCE Therapeutic Level III.

Abstract
PURPOSE Early femoral component migration is a useful indicator for identifying implants at risk of failure due to aseptic loosening. The goal of this retrospective study was to identify if anterior approach (AA) treated hips are at a higher risk of failure due to aseptic loosening caused by early migration compared to hips operated on using the traditional posterior approach (PA). METHODS A total of 388 hips were included in this study, 139 AA and 249 PA treated hips. Femoral component migration was evaluated using EBRA-FCA and radiographs were assessed for radiolucency at latest follow-up. Preoperative and 2-year clinical outcomes were reported. RESULTS The 1- and 2-year migration rates (mm/year), and total migration (mm) at 2-year follow-up were comparable between AA and PA hips, respectively: 0.52 versus 0.41, 0.18 versus 0.19, and 0.64 versus 0.63 (all p > 0.05). Though not statistically significant, a higher percentage of AA hips passed 2-year total migration thresholds that have been associated with aseptic loosening compared to PA hips: 25.4% versus 16.5% for 1.5 mm threshold, and 11.3% versus 4.1% for the 2.7 mm threshold. Migration was not associated with the presence of radiolucent lines. All clinical outcomes improved significantly between preoperative and 2-year follow-up. CONCLUSIONS There was no association between the AA and any significant increase in femoral component migration. A higher percentage of AA hips exceeded the migration thresholds associated aseptic loosening; however, these stems had no other indications of instability and therefore suggests that this may be a difference in migration pattern.

Abstract
OBJECTIVE A systematic review and meta-analysis were used to directly evaluate the direct anterior approach (DAA) and the posterior approach (PA) for early efficacy and safety of total hip arthroplasty (THA). METHODS Control-led trials assessing DAA and PA for the efficacy and safety of THA were searched in the database. Articles were reviewed according to predetermined inclusion and exclusion criteria; the quality of the methodology included in a given study was strictly assessed before data extraction. Moreover, meta-analysis was performed for outcomes that can be combined; otherwise, descriptive analysis was performed. RESULTS There were 20 articles included, with a total of 7377 patients. Among these, 3728 and 3649 cases were in the DAA and PA groups, respectively. There was no difference between the DAA and PA groups at postoperative week 2 in the number of patients using the assistive ambulatory device or in time needed to completely discontinue all assistive ambulatory devices. Descriptive analysis found that DAA was slightly better than PA regarding early functional recovery and activity after surgery, as well as postoperative pain relief. Hospitalisation stay in the DAA group was shorter than in the PA group, in which the patients had a shorter operative time. Radiographic outcomes showed that there was little difference in prosthetic position between the DAA and PA groups. The proportions of intraoperative fractures and postoperative lateral cutaneous nerve of the thigh (LCNT) neuropraxia were significantly higher in the DAA group than in patients who underwent PA. CONCLUSION Compared with PA, DAA presents superior early recovery following THA.

Abstract
Vascular injury following total hip arthroplasty (THA) is a rare but known complication. Various vascular lesions have been described in the literature, with arterial intimal damage being uncommon. Despite the recent popularity of the direct anterior approach in THA, only 1 case of iatrogenic vascular injury has been reported. We report 3 cases of common femoral artery intimal damage with thrombosis following direct anterior THA. We propose that misplacement of the anterior retractor in this approach, especially in certain susceptible patients, can lead to vascular damage. Therefore, maintaining a step-wise approach to placing the retractor with caution is essential. One of our cases had a delayed presentation of undetectable arterial pulse, highlighting the significance of regular postoperative vascular examinations.

Abstract
BACKGROUND The direct minimally invasive anterior approach (DMIAA) in total hip arthroplasty (THA) is widely accepted. In our department the DMIAA according to Rachbauer together with the Trident cup and Accolade stem was introduced in 2004. The purpose of the study was to demonstrate the five-year results and to analyze the learning curve of a new introduced approach. PATIENTS AND METHODS Between July 2004 and May 2006, a consecutive series of 151 THA in 147 patients was retrospectively analyzed. All patients were planned to received a THA with the Accolade/Trident implant system using the DMIAA without traction table. Clinical and radiographic data, complications and survivorship were documented with a follow-up of at least 5 years. RESULTS Regarding cup implantation, there were 11 (7.3%) failed intentions to treat due to missing pressfit (8 cases) and acetabular floor perforation (3 cases). No failed intentions to treat occurred during stem implantation. Total implant survival after 5 years follow-up after exclusion of 11 cases with failed intention to treat (N=140) was 96.9% (SD 1.4; CI 94.3-99.6). After exclusion of the failed intentions to treat (N=140, N=4 in the first 20 cases), there was significant (p<0.001) difference between the first 16 implants with a 5 year-survival of 83.2% (SD 8.6; CI 66.4-100) and 95.7% (SD 0.9; CI 93.9-97.5) for the following 124 implants. Radiolucent lines were observed in Gruen zone 1 in 3.3% and in Gruen zone 1 and 2 in 1.1%. DISCUSSION THA with Accolade/Trident using the DMIAA without traction table according to Rachbauer temporary exposed patients to a higher risk of implant revisions, which was normalized after the first 20 cases. Results of the learning curve are comparable to other techniques using an orthopaedic traction table. After the typical learning curve, the rate of 5 years implant failure is in accordance with the registry data for non-cemented implants. The Accolade stem showed minimal radiographic signs of radiolucency. LEVEL OF EVIDENCE IV, retrospective, consecutive case series.

Abstract
BACKGROUND The purpose of this study was to document complications, outcomes, and 10-year survivorship of primary total hip arthroplasty (THA) using a direct anterior approach with an uncemented, straight, hydroxyapatite-coated stem and an uncemented cup. METHODS A retrospective, consecutive series of 275 primary THAs through a direct anterior approach with traction table using Medacta Versafit cup and Quadra-H stem with a minimum of 10-year follow-up was identified. The cumulative 10-year survival of the implants was estimated using Kaplan-Meier estimator. All complications, reoperations, and failures were analyzed. Subjective and clinical outcomes (Subjective Hip Value, Western Ontario and McMaster Universities Osteoarthritis Index, and Harris Hip Score) were measured. RESULTS Of 256 patients (275 hips, 143 men and 113 women) with a mean age of 63 (range, 24-85) years, 48 (19%) patients (52 hips) deceased not related to the surgery after a mean time 49 months (range, 3-118) postoperatively. At >10-year follow-up, 9 THAs were revised. The overall implant survival rate was 96.8% (95% confidence interval, 94.4-98.7) at 10 years. One cup and 1 stem were revised because of aseptic loosening. At the last follow-up, the median Subjective Hip Value was 90% (range, 20-100), the Western Ontario and McMaster Universities Osteoarthritis Index score reached a median of 0.2 points (range, 0-6.3), and the median Harris Hip Score points was 99 (range, 29-100). CONCLUSION Primary THA through an anterior minimal invasive approach with the mentioned implants showed low revision rates and good to excellent clinical outcome after at least 10 years.

Abstract
Background Appropriate component positioning in total hip arthroplasty (THA) is imperative for long-term survivorship. C-arm fluoroscopy provides visual guidance in the direct anterior approach (DAA), but it is limited by qualitative properties. Conversely, imageless computer-assisted navigation systems (CAS) provide surgeons with intraoperative, three-dimensional (3D) quantitative measurements for cup position, although the accuracy of such systems has not been extensively addressed in the DAA. We evaluated the ability of an imageless CAS to deliver measurements for acetabular cup position with accuracy in the DAA. Materials and methods A retrospective analysis of 69 primary THA procedures was conducted. Acetabular cup position measurements (anteversion and inclination) obtained intraoperatively by imageless navigation were compared to standard, postoperative anteroposterior pelvic radiographic measurements. Statistical comparisons were made using the Bland-Altman technique. Results The mean difference between device and radiographic measurements for anteversion was 3.4° (standard deviation (SD): 4.1°; absolute mean difference (ABS): 4.2°), and 4.0° for inclination (SD: 3.6°; ABS: 4.3°). Bland-Altman analysis demonstrated excellent agreement; 93% (64/69) and 97% (67/69) of anteversion pairings fell within the statistical and clinical limits of agreement, whereas 94% (65/69) and 100% (69/69) of inclination pairings were within the statistical and clinical limits, respectively. Conclusions Measurements obtained intraoperatively for acetabular cup position using imageless navigation in the DAA are agreeable with the current clinical standard.

Abstract
The direct anterior approach to the hip for total joint arthroplasty has been suggested to have several advantages compared to other popular approaches through its use of a natural intramuscular and intra-nervous interval. Recent emphasis on tissue sparing and minimally invasive outpatient joint replacements has given rise to a significant increase in the utilization of direct anterior total hip arthroplasty (DAA). Proponents of this approach cite improved recovery times, lower pain levels, improved patient satisfaction as well as improved accuracy on both implant placement/alignment and leg length restoration. A number of variations of the procedure have been described and many authors have published their experiences and technical keys to successfully accomplishing this procedure. Described techniques have been performed using specifically designed instruments and specific fracture tables and intra-operative flouroscopy, however this approach may be performed using a regular table with standard arthroplasty tools with alternative patient positioning and without intraoperative imaging. This review summarizes several aspects of the direct anterior approach for total hip arthroplasty and its comparison to other popular approaches to modern hip replacement.

Abstract
SURGICAL PRINCIPLE AND OBJECTIVE The direct anterior approach for total hip arthroplasty is associated with higher complication rates and difficult femoral component positioning. Performing a modified technique in the lateral position allows secure component positioning. INDICATIONS Primary hip replacement (including femoral neck fracture) and cup revision without bone deficiency. CONTRAINDICATIONS Destruction/deformities of proximal femur or acetabulum, bone deficiency or malignancy. SURGICAL TECHNIQUE Strict lateral decubitus position. Straight anterior incision of 10-12 cm, starting 2 cm lateral to the anterior superior iliac spine. Incision of the fascia over the tensor fascia lata muscle (TFL). Lateral retraction of the TFL. Incision of the fascia and medial retraction of rectus femoris. Ligation of the ascending branch of the lateral femoral circumflex artery. Detachment of the iliocapsularis muscle from the capsule in a medial direction. Anterior capsule excision. Femoral neck osteotomy and removal of the head. Reaming of the acetabulum; insertion the acetabular component. Exposure of the femur. Incision/excision of the capsule medial to the greater trochanter for easy anteriorization of the femur. Reaming and implantation of femoral component. POSTOPERATIVE MANAGEMENT Weight bearing on day one with crutches for 4 weeks; deep vein thrombosis prophylaxis. RESULTS In all, 138 patients (72 women, 66 men, mean age of 67 years) were followed up over 2 years. Overall complication rate was 3.6%: 3 patients (2.2%) with grade III complications required additional intervention. Acetabular cup inclination: 35-50° in 88% of patients. Neutral femoral stem position observed in 99% of patients. Mean Harris hip score improved from 61 preoperatively to 97 after 2 years. Patient satisfaction on a visual analogue scale improved from 3.7 to 9.5.

Abstract
Introduction Computer-assisted navigation systems have been explored in total hip arthroplasty (THA) to improve component positioning. While these systems traditionally rely on anterior pelvic plane registration, variances in soft tissue thickness overlying anatomical landmarks can lead to registration error, and the supine coronal plane has instead been proposed. The purpose of this study was to evaluate the accuracy of a novel navigation tool, using registration of the anterior pelvic plane or supine coronal plane during simulated anterior THA. Methods Measurements regarding the acetabular component position, and changes in leg length and offset were recorded. Benchtop phantoms and target measurement values commonly seen in surgery were used for analysis. Measurements for anteversion and inclination, and changes in leg length and offset were recorded by the navigation tool and compared with the known target value of the simulation. Pearson's r assessed the relationship between the measurements of the device and the known target values. Results The device accurately measured cup position and leg length measurements to within 1° and 1 mm of the known target values, respectively. Across all simulations, there was a strong, positive relationship between values obtained by the device and the known target values (r=0.99). Conclusion The preliminary findings of this study suggest that the novel navigation tool tested is a potentially viable tool to improve the accuracy of component placement during THA using the anterior approach.

Abstract
Objective To compare the effectiveness of one-stage bilateral total hip arthroplasty by direct anterior approach (DAA) and by posterolateral approach, and to investigate the application value of DAA in one-stage bilateral total hip arthroplasty. Methods The clinical data of 65 patients who underwent one-stage bilateral total hip arthroplasty by DAA or posterolateral approach between June 2010 and November 2015 were analyzed retrospectively. DAA was used in 34 cases (group A) and posterolateral approach was used in 31 cases (group B). There was no significant difference in the gender, age, body mass index, preoperative hemoglobin level, etiology, disease duration, preoperative Harris score, and preoperative visual analogue scale (VAS) score between 2 groups ( P>0.05) with comparability. The incision length, operation time, intraoperative blood loss, total blood transfusion volume, hospitalization time, early postoperative complications, Harris score, and VAS score were recorded and compared between 2 groups. The simple Likert scale method was applied to evaluate the patient satisfaction, and the imaging evaluation was used. Results The incision length, operation time, intraoperative blood loss, total blood transfusion volume, and hospitalization time of group A were significantly less than those of group B ( P<0.05). The patients were followed up 15-48 months (mean, 25.3 months) in group A and 12-51 months (mean, 27.6 months) in group B. The overall incidence of complications related to surgery in group A (10.29%) was significantly lower than that of group B (19.35%) ( χ2=8.769, P=0.023). The acetabular anteversion and abduction angle were in the normal range of 2 groups except 1 hip (1.47%) of group A had a higher acetabular anteversion than normal value. Unstable fixed prosthesis happened in 1 hip of groups A and B respectively, and the remaining femoral calcar had no obvious bone resorption and fixed stably. The Harris score and VAS score at each time point after operation of 2 groups were significantly improved when compared with preoperative scores ( P<0.05), and the differences between the time points after operation were also significant ( P<0.05). The Harris score at 1 and 3 months after operation and the VAS score at 3 days after operation of group A were significantly better than those of group B ( P<0.05), but no significant difference was found at last follow-up between 2 groups ( P>0.05). According to the simple Likert scale method to analyze patient satisfaction, comprehensive satisfaction of group A (97.1%, 33/34) was significantly higher than that of group B (67.7%, 21/31) ( χ2=10.343, P=0.001). Conclusion The application of DAA in one-stage bilateral total hip arthroplasty can significantly relieve the pain, accelerate the recovery of hip joint function, and improve the patient satisfaction. But in clinical application, more attentions should be paid to strictly grasp the indications and prevent the early complications. The long-term effectiveness needs to be further observed.

Abstract
BACKGROUND The quest for less invasive surgical approaches for total hip arthroplasty (THA) has garnered much attention recently in the community, as well as media outlets. There are very little data demonstrating the actual differences in these approaches. We are unaware of any information documenting patients' perceptions of the direct anterior approach (DAA) for THA. The purpose of this study was to collect information regarding patients' perceptions of the DAA THA. METHODS We surveyed 166 consecutive new patients being evaluated for hip osteoarthritis in our outpatient clinic. Demographic data and their knowledge of the DAA were collected, as well as a number of questions on a 5-item Likert scale. RESULTS Forty-six (28%) responded that they were aware of the DAA. Respondents primarily learned about the DAA from friends and family (58%), and healthcare professionals (38%). Respondents agreed or strongly agreed that the DAA is less painful (70%), reduces the amount of time spent on a cane after surgery (70%), damages tissues less (68%), allows patients to more quickly return to work (64%), and allows for shorter hospital stays (62%), compared to other procedures. In addition, 30% felt there is a consensus among surgeons that the DAA is the safest and most effective procedure for THA. CONCLUSION Many people are unaware of the DAA, with a majority of healthcare information being transmitted by friends and family members. The patients' perceptions are inconsistent with published data about the DAA and are likely influenced by marketing and individuals surrounding them.

The Direct Anterior Approach is Associated With Early Revision Total Hip Arthroplasty. J Arthroplasty 2017; 32:1001-1005.

Abstract
BACKGROUND The direct anterior approach for total hip arthroplasty (THA) has generated increased interest recently. The purpose of this study was to compare the duration to failure and reasons for revision of primary THA performed elsewhere and subsequently revised at our institution after the direct anterior vs other nonanterior surgical approaches to the hip. METHODS All primary THAs performed elsewhere and referred to our institution for revision were divided into the direct anterior approach (30 cases) or nonanterior approach groups (100 cases, randomly selected from 453 cases) based on the original surgical approach. Because all primary direct anterior THAs were originally performed after 2004 to eliminate temporal bias, we identified a subset of the nonanterior group in which the primary THA was performed after 2004 (known as the recent nonanterior group, 100 cases, randomly selected from 169 available cases). RESULTS The mean duration from primary to revision THA was 3.0 ± 2.7 years (direct anterior approach), 12.0 ± 8.8 years (nonanterior approach), and 3.6 ± 2.8 years (recent nonanterior), respectively. There was a significant difference in time to revision between the direct anterior and nonanterior approach groups (P < .001). Aseptic loosening of the stem was significantly more frequent with the direct anterior approach group (9/30, 30.0%) when compared with the nonanterior group (8/100, 8.0%, P = .007) and the recent nonanterior group (7/100, 7.0%, P = .002). CONCLUSION Revision of the femoral component for aseptic loosening is more commonly associated with the direct anterior approach in our referral practice.

Abstract
AIMS We assessed the difference in hospital based and early clinical outcomes between the direct anterior approach and the posterior approach in patients who undergo total hip arthroplasty (THA). PATIENTS AND METHODS The outcome was assessed in 448 (203 males, 245 females) consecutive patients undergoing unilateral primary THA after the implementation of an 'Enhanced Recovery' pathway. In all, 265 patients (mean age: 71 years (49 to 89); 117 males and 148 females) had surgery using the direct anterior approach (DAA) and 183 patients (mean age: 70 years (26 to 100); 86 males and 97 females) using a posterior approach. The groups were compared for age, gender, American Society of Anesthesiologists grade, body mass index, the side of the operation, pre-operative Oxford Hip Score (OHS) and attendance at 'Joint school'. Mean follow-up was 18.1 months (one to 50). RESULTS There was no significant difference in mean length of stay (p = 0.07), pain scores on the day of surgery, the first, second and third post-operative days (p = 0.36, 0.23, 0.25 and 0.59, respectively), the day of mobilisation (p = 0.12), the mean OHS at six and 24 months (p = 0.08, and 0.29, respectively), the incidence of infection (p = 1.0), dislocation (p = 1.0), re-operation (p = 0.21) or 28 days' re-admission (p = 0.06). Significantly more patients in the DAA group achieved a planned discharge target of three days post-operatively (68% vs 56%, p = 0.007). The rate of periprosthetic femoral fractures was significantly higher in the DAA group (p = 0.04). CONCLUSION We conclude that there is no difference in clinical outcomes between the DAA and the posterior approach in patients undergoing THA when an 'Enhanced Recovery' pathway is used. However, a significantly higher rate of periprosthetic femoral fractures remains a concern with the DAA, even in experienced hands. TAKE HOME MESSAGE Our results show that the DAA for THA is not superior to posterior approach when 'Enhanced Recovery' pathway is used. Cite this article: Bone Joint J 2016;98-B:754-60.

Abstract
Objective To evaluate the short-term effectiveness of minimally invasive total hip arthroplasty (THA) by direct anterior approach (DAA). Methods Between January and August 2014, THA was performed on 48 patients (60 hips) by DAA (group A), and on 72 patients (92 hips) by posterolateral approach (group B). There was no significant difference in gender, age, etiology, course, and preoperative visual analogue scale (VAS), Harris hip score (HHS), and hip range of motion (ROM) between 2 groups ( P>0.05). The operation time, intraoperative blood loss, postoperative drainage, hospitalization time, incision healing, and complications were recorded and compared. The acetabular abduction and anteversion were measured on the X-ray films; prosthesis loosening was observed. The VAS score, HHS score, and hip ROM were used to evaluate the hip function. Results The operation time and intraoperative blood loss of group A were significantly higher than those of group B, and the hospitalization time was significantly lower than group B ( P<0.05), but no significant difference was found in postoperative drainage between 2 groups ( t=0.71, P=0.46). The patients were followed up 2-2.5 years (mean, 2.2 years) in group A, and 2-2.5 years (mean, 2.1 years) in group B. In group A, 3 cases had lateral femoral cutaneous nerve traction injury and 1 case had swelling and exudate, and primary healing of incision was obtained in the other cases of group A and all cases of group B. No periprosthetic joint infection occurred in the others of groups A and B except 1 case of group A at 2 months after operation, and infection was controlled after debridement, irrigation, and intravenous infusion of Vancomycin for 1 month. The X-ray films showed good position of prosthesis and no obvious radiolucent line or prosthesis loosening. There was no significant differences in acetabular abduction and anteversion between groups A and B at last follow-up ( P>0.05). The VAS score, HHS score, and hip ROM at 3 months and last follow-up were significantly better than preoperative ones in 2 groups ( P<0.05), but no significant difference was found between at 3 months and last follow-up ( P>0.05). The VAS score, HHS score, and hip ROM in group A were significantly better than those in group B at 3 months postoperatively ( P<0.05). At last follow-up, the hip ROM in group A was significantly better than that in group B ( P<0.05), and there was no significant difference in VAS and HHS scores between group A and group B ( P>0.05). Conclusion The short-term effectiveness of minimally invasive THA by DAA is satisfactory, with the advantage of little trauma, short hospital stay, and rapid postoperative recovery.

Abstract
There is still discussion about possible advantages and disadvantages of the less invasive anterior approach for total hip arthroplasty (THA). The purpose of our systematic review was to evaluate literature regarding the anterior approach in comparison to other approaches. Furthermore, we investigated if there is a description of a learning curve for the anterior approach.Data were obtained from EMBASE, Cochrane, PsycINFO, CINAHL, Web-of-Science, Scopus, Google scholar, and PubMed since their inception up to June 2015. 2 reviewers independently selected the studies and independently conducted the quality assessment. Because studies were considered heterogeneous regarding outcome measures, determinants studied, and methodological quality, we decided to perform a "best evidence synthesis". A total of 64 studies met the inclusion criteria.Strong evidence for no difference in component placement between the anterior approach and other approaches was found. Also, strong evidence for faster postoperative recovery and less need for assistive devices after the anterior approach were found. All other studied parameters only demonstrated conflicting evidence. Although the learning curve for the anterior approach is not yet clear, this learning curve should not to be neglected.In conclusion, the less invasive anterior approach provides benefits in the early postoperative period only, when compared to other approaches.

Abstract
BACKGROUND The direct anterior approach (DAA) for the treatment of total hip arthroplasty (THA) has gained popularity in recent years. Chip fractures of the greater trochanter are frequently seen, but the risk factors for such fractures are unknown. The study aimed to identify the risk factors for chip fractures in patients undergoing primary THA by the DAA during the surgeons' learning curve. MATERIALS AND METHODS From November 2011 to April 2015, the first experiences of three surgeons who performed 120 THAs by the DAA (120 hips; 40 cases per beginner surgeon) were included. The incidence of chip fracture of the greater trochanter, the size of the greater trochanter as measured by computed tomography, and the patients' characteristics were retrospectively investigated. RESULTS After exclusion of 11 hips, the remaining 109 hips were investigated. Chip fracture of the greater trochanter was identified in 32 hips (29.4 %). Univariate analysis with and without fractures showed that the width and depth of the greater trochanter were statistically significant risk factors (p = 0.02 and p < 0.001, respectively). Multivariate analysis using a logistic regression model demonstrated that the depth of the greater trochanter was an independent risk factor for chip fracture of the greater trochanter (OR 1.725; 95 % CI 1.367-2.177; p < 0.001). CONCLUSION The size of the greater trochanter was identified as a risk factor for chip fracture of the greater trochanter. Novice surgeons should pay attention to the size of the greater trochanter when performing THA by the DAA.

First experiences with the direct anterior approach in lateral decubitus position: learning curve and 1 year complication rate. Hip Int 2016; 25:251-7.

Abstract
The direct anterior approach (DAA) in supine position for hip arthroplasty has been reported to suffer from high complication rates initially. The DAA with the patient in lateral decubitus position is believed to provide better visibility and especially femoral accessibility with potential fewer complications.The first cohort of total hip prostheses, which were implanted by a single surgeon using DAA in lateral decubitus position more than 1 year ago, was analysed retrospectively.In total 182 hip prostheses (172 patients) were analysed. Three consecutive time periods based on equal number of surgical procedures were compared. The technical complication rate and operating time improved significantly between the 3 consecutive groups. The 1 year infection rate was 0.5% and survival rate of 98.9%.This is the first series of patients that were subjected to a hip replacement based on the direct anterior approach in a lateral decubitus position in which decreasing complication rates suggest the presence of a learning curve in surgeons conducting this type of surgery. Initial complication rate was high but decreased significantly in time and was acceptable certainly in the third group of our cohort. An unacceptable complication rate with the straight uncemented stem forced us to discontinue this configuration after only 7 surgical procedures. Complication, infection and revision rates were acceptable for the all cemented hip replacements using a curved anatomical stem.

Abstract
Direct anterior total hip arthroplasty has become increasingly more popular among arthroplasty surgeons, in large part due to the use of an intramuscular interval and desire to reduce soft tissue damage. Several studies have now been published comparing the anterior intramuscular to other commonly used approaches, and many studies have published complication rates on large series of patients. Review of comparative studies indicates direct anterior hips tend towards shorter hospital stays and high rates of patients discharged to home. Although some studies show evidence of early benefit in functional outcomes, there is no strong evidence that the anterior approach provides any long term functional improvements compared to other approaches. Additionally, evidence to support reduced damage to soft tissue may not translate to certain clinical significance. Rates of intra-operative femur fracture, operative time and blood loss rates are notably higher for those developing familiarity with this approach. However, when surgeons have performed a modest number of procedures, the complication rates tend to markedly decrease in most studies to levels comparable to other approaches. Accuracy of component positioning also favors the anterior approach in some studies. This review summarizes the available literature comparing the direct anterior to other approaches for total hip arthroplasty and provides a comprehensive summary of common complications.

Abstract
The direct anterior approach to the hip has been suggested to have several advantages compared to previously popular approaches through its use of an intra-muscular and intra-nervous interval between the tensor fasciae latae and sartorius muscles. Recent increased interest in tissue-sparing and minimally-invasive arthroplasty has given rise to a sharp increase in the utilization of direct anterior total hip arthroplasty. A number of variations of the procedure have been described and several authors have published their experiences and feedback to successfully accomplishing this procedure. Additionally, improved understanding of relevant soft tissue constraints and anatomic variants has provided improved margin of safety for patients. The procedure may be performed using specially-designed instruments and a fracture table, however many authors have also described equally efficacious performance using a regular table and standard arthroplasty tools. The capacity to utilize fluoroscopy intra-operatively for component positioning is a valuable asset to the approach and can be of particular benefit for surgeons gaining familiarity. Proper management of patient and limb positioning are vital to reducing risk of intra-operative complications. An understanding of its limitations and challenges are also critical to safe employment. This review summarizes the key features of the direct anterior approach for total hip arthroplasty as an aid to improving the understanding of this important and effective method for modern hip replacement surgeons.

Abstract
The direct anterior approach has recently gained popularity for patients undergoing elective total hip arthroplasty. It is unknown whether the reported benefits of the direct anterior approach to elective total hip arthroplasty can be extrapolated to patients undergoing hemiarthroplasty after femoral neck fracture. A retrospective review of 101 patients was performed to compare the outcomes of patients treated with hemiarthroplasty using the direct anterior approach (group 1) with those of patients undergoing the procedure with the posterior, anterolateral, or lateral approach (group 2). No differences in age, American Society of Anesthesiologists classification, and preinjury ambulatory status were identified between treatment groups. No difference in operative time was found between those undergoing the anterior approach (98.7 minutes) and those undergoing other surgical approaches (96.5 minutes) (P=.76). No difference in either the need for transfusion or the number of blood products transfused was seen (P=.21) postoperatively. Patients undergoing the direct anterior approach were more likely to be discharged by postoperative day 3 (P=.004) despite no difference in the recorded number of feet ambulated in the hospital. At a mean clinical follow-up of 16 weeks, there was no difference in the rate of return to baseline ambulatory status between groups (P=.07). The overall rates of major and minor complications for all patients were 23% and 26%, respectively, with no statistically significant differences between groups. The overall dislocation rate of all patients was found to be 3%. All dislocations were observed in group 2. Larger prospective studies are needed to further define the benefits of the direct anterior approach in this patient population.

Comparison of Cup Alignment, Jump Distance, and Complications in Consecutive Series of Anterior Approach and Posterior Approach Total Hip Arthroplasty. J Arthroplasty 2015; 30:1959-62. [PMID: 26051865 DOI: 10.1016/j.arth.2015.05.022] [Citation(s) in RCA: 60] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/17/2014] [Revised: 04/30/2015] [Accepted: 05/07/2015] [Indexed: 02/01/2023] Open
Abstract
The purpose of this study was to compare cup position, jump distance, and rate of dislocations in 100 total hip arthroplasty (THA) cases performed with the direct anterior approach (DAA) and 100 cases performed with the posterior approach (PA). Abduction and anteversion angles were measured using Martell Hip Analysis software. The average cup anteversion in the DAA group (17.6°) was significantly different than the PA average (22.6°), P<.001. The average cup abduction angle was similar between groups (DAA 44.2° vs. PA 44.3°, P=.87), but the variance was significantly reduced with the direct anterior approach, P=.02. The use of intraoperative fluoroscopy with the DAA allowed for more accurate cup placement and eliminated severely vertical cups (>55°) seen with the PA.

Abstract
INTRODUCTION The direct anterior approach (DAA) is an increasingly popular technique for performing total hip arthroplasty (THA). This muscle-sparing approach may yield functional benefits. However, DAA has been associated with an increased risk incidence (RI) of intra- and postoperative complications. MATERIALS AND METHODS A systematic review of the published literature was conducted to document the cumulative RI of intra- and postoperative complications, as well as the presence of a learning curve in subjects undergoing THA with a DAA. Study selection and data extraction were carried out independently in duplicate. A Bayesian zero-inflated random-effect model was used to calculate pooled estimates for the different endpoints. RESULTS Thirty-eight studies (6485 patients) were analysed. RIs of 0.8 % [95 % confidence interval (CI): 0.4-1.6 %] and 0.5 % (95 % CI: 0.3-0.9 %) were found for intra-operative trochanter and femoral fractures, respectively, and of 0.9 % (95 CI: 0.3-2.6 %) for postoperative transient lateral cutaneous femoral nerve (LCFN) impairment. A clear RI for early revisions (2.1 %; 95 % CI: 1.4-2.8 %) and other surgical re-interventions (1.3 %; 95 % CI: 0.7-1.9 %) was present, but these values do not differ from reported RIs for THA overall. The RI for dislocation was low (0.6 %; 95 % CI: 0.4-0.9 %) compared with the reported literature. CONCLUSIONS DAA is a technically demanding procedure, with outcomes possibly indicative of surgeon learning curve. A risk for intra-operative fractures and LCFN is evident, although the risk for other adverse effects is comparable to those with other approaches.

Abstract
The direct anterior (DA) approach for total hip arthroplasty (THA) has demonstrated successful short term outcomes in several studies. However, there is no consensus about which patients are appropriate candidates for DA total hip arthroplasty. It is also unclear if short term outcomes in obese patients undergoing THA through a DA approach are elevated in comparison to non-obese patients. The purpose of this study was to evaluate complication rates and short term outcomes of obese, pre-obese, and normal body mass index (BMI) patients undergoing THA with a DA approach in a consecutive group of patients. This study was a retrospective review of 210 consecutive patients who underwent unilateral THA through a DA approach for osteoarthritis or avascular necrosis during the early peri-operative period. The study included 61 patients with normal BMI, 70 pre-obese patients, and 79 obese patients according to World Health Organization (WHO) classification (49 class I obese, 22 class II obese, and 8 class III obese patients). Patient charts were reviewed to determine differences in surgical time, length of stay, disposition, major complications, wound complications, and short term outcome measures. When comparing normal and pre-obese patients (BMI <30) to a combined group of WHO class I, II, and III obese patients (BMI >30), the obese group demonstrated increased surgical times by 12.7 minutes (P<0.0001), as well as increased length of stay (P=0.0303), narcotic use (P=0.0037), and assistive device use at two weeks (P<0.0030). In addition, major complications and wound complications were both significantly increased in the obese group (odds ratio [OR], 8.8; P=0.0493 and OR, 3.6; P=0.0431, respectively). There was also a trend toward increased use of rehabilitation facilities in the obese group at disposition, 15.4% vs 7.6% (P=0.0774). This study demonstrates that obese patients undergoing a DA approach have a 8.8 and 3.6 times increase in major and wound complications, respectively, compared to patients with a BMI <30. Obese patients also demonstrated significant increases in operative time, use of narcotics, use of assistive devices, and length of stay. There was a trend toward higher use of rehabilitation placement. While significant, these findings are similar to complication rates in the literature for other THA operative approaches. This study further defines the risks associated with performing THA on obese patients regardless of approach.

Abstract
Direct anterior approaches to the hip have gained popularity as a minimally invasive method when performing primary total hip replacement (THR). A retrospective review of a single institution joint registry was performed in order to compare patient outcomes after THR using the Anterior Supine Intermuscular (ASI) approach versus a more conventional direct lateral approach. An electronic database identified 1511 patients treated with 1690 primary THRs between January 2006 and December 2010. Our results represent a summary of findings from our previously published work. We found that patients that underwent an ASI approach had faster functional recovery and higher Harris hip scores in the early post-operative period when compared with patients who had a direct lateral approach The overall complication rate in our ASI group was relatively low (1.7%) compared with other series using the same approach. The most frequent complication was early periprosthetic femoral fractures (0.9%). The dislocation rate in our series was 0.4% and the prosthetic joint infection rate was 0.1%. We suggest that the ASI approach is acceptable and safe when performing THR and encourages early functional recovery of our patients. Cite this article: Bone Joint J 2014;96- B(11 Suppl A):32–5.
