Hip Arthroscopy Versus Conservative Treatment for Borderline Hip Dysplasia
The goal of this clinical trial is to compare the efficacy of hip arthroscopy versus individualized conservative treatment in patients with borderline developmental dysplasia of the hip (BDDH), defined by a lateral center-edge angle (LCEA) of 18-25°. The main question it aims to answer is: which treatment approach, surgical or conservative, provides superior pain relief, functional recovery, and quality of life improvement at 12 and 24 months post randomization? 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). Secondary outcomes include patient-reported outcome measures (VAS pain, iHOT-12, SF-12, and patient satisfaction), clinical assessments, and safety monitoring.
