Participants will be randomly assigned (1:1) to either standardized hip arthroscopy, comprising capsular management, acetabular rim limited trimming, labral repair, and Cam deformity correction when indicated; or a 3-month individualized conservative protocol including patient education, nonsteroidal anti-inflammatory drugs (NSAIDs) for 2-4 weeks, chondroprotective supplementation for 8 weeks, and supervised progressive exercise training. All participants will undergo follow-up assessments at baseline, 12, and 24 months. The primary outcome is the modified Harris Hip Score (mHHS).
