Preoperative anxiety and depression predict two-year outcomes after total hip or knee arthroplasty

Figure 1 Postoperative functional recovery: Comparison of Harris Hip and Hospital for Special Surgery Knee Scores between exposure groups over 2 years. A: Comparison of Harris Hip Scores between groupsin total hip arthroplasty patients. The graph shows the trends in Hardship scores for the non-exposure group (n = 53) and exposure group (n = 42) at preoperative, 1-year postoperative, and 2-year postoperative time points. Both groups had similar baseline scores (approximately 45) preoperatively, with improvement over time. At 2 years postoperatively, the non-exposure group reached approximately 90 points, while the exposure group reached approximately 83 points. Error bars indicate standard deviation; B: Comparison of Hospital for Special Surgery Knee Scores between groups in total knee arthroplasty patients. The graph shows the trends in Hospital for Special Surgery knee scores for the non-exposure group (n = 39) and exposure group (n = 40) at preoperative, 1-year postoperative, and 2-year postoperative time points. Both groups had similar baseline scores (approximately 50) preoperatively, with significant improvement over time. At 2 years postoperatively, the non-exposure group reached approximately 87 points, while the exposure group reached approximately 81 points. Error bars indicate standard deviation.
