Summary: Arthroscopic acetabular labral debridement resulted in significantly better clinical and quality-of-life outcomes in patients with CE angle >25° compared with patients with CE angle < 25°.
To compare clinical and quality-of-life outcomes following arthroscopic acetabular labral debridement between patients with different center edge (CE) angle
A total of 79 patients who underwent hip labral debridement were enrolled in this study. Radiographic measurements of center edge (CE) angle were collected, and patients were assigned into normal group (CE angle>25°, <40° n=68) and dysplasia group (CE angle <20° n=11). The mean age at the time of surgery was 41.1 years (range, 20-52 years) in normal group and 39.7 years (range, 21-49 years) in dysplasia group. The average follow-up duration was 29.1 months (range, 14-81 months) in normal group and 25.3 months (range, 16-79 months) in dysplasia group, respectively. Clinical outcomes were evaluated by modified Harris Hip Score (mHHS), Hip Outcome Score (HOS) for activities of daily living and sports, health-related measures (12-Item Short Form Health Survey [SF-12]).
At the final follow-up, normal group showed significant improvements in mHHS, HOS (ADL and sports) and SF-12 (P< 0.05). However, 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, the postoperative mHHS, HOS (ADL) and SF-12 PCS were significantly better in normal group compared with dysplasia group (P< 0.05).
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°.
