Abstract
PURPOSE: The aim of this study was to compare clinical and quality of life outcomes following arthroscopic acetabular labral debridement between patients with different centre-edge (CE) angle. METHODS: A total of 79 patients who underwent hip labral debridement were enrolled in this study. Radiographic measurements of CE angle were collected, and patients were assigned into a normal group (25° < CE angle <40°, n = 68) and dysplasia group (CE angle <20°, n = 11). Clinical outcomes were evaluated by modified Harris Hip Score (mHHS), Hip Outcome Score (HOS) for activities of daily living (ADL) and sports and Short Form 12 (SF-12). RESULTS: At the final follow-up, the normal group showed significant improvements in mHHS, HOS (ADL and sports) and SF-12 (P < 0.05). However, the dysplasia group revealed significant improvements in mHHS, HOS (ADL) and SF-12 physical component summary (PCS) (P < 0.05) and no significant changes in HOS sports and SF-12 mental component summary (MCS) (P > 0.05). Additionally, there was a greater improvement in clinical scores post-operatively in the normal group compared with the dysplasia group (P < 0.05). CONCLUSIONS: Arthroscopic acetabular labral debridement resulted in significantly greater clinical and quality of life outcomes in patients with CE angle >25° compared with patients with CE angle < 20°.
