Core Tip
Core Tip: The clinical efficacy of conservative hip preservation treatment has always been a vague concept. This study reviewed 119 hips with an average follow-up time of 4 years (including the longest 10 years), and demonstrated through radiological findings and clinical functional scores that conservative hip preservation treatment can achieve certain long-term good therapeutic effects. It may contribute to enhancing hip joint function and postponing the need for arthroplasty.
