Return to Sport and Clinical Outcomes After Hip Arthroscopic Labral Repair in Young Amateur Athletes: Minimum 2-Year Follow-Up

摘要

Purpose: To determine the rate of return of young amateur athletes to sport after hip arthroscopy, their clinical outcomes, and pathologic risk factors for worse outcomes 2 years after surgery. Methods: This study included all patients between age 13 and 23 who participated in a sport prior to surgery with intent to return who underwent hip arthroscopy after failure of comprehensive nonoperative management for whom 2-year outcome scores were available. Outcomes collected retrospectively included modified Harris Hip Score (mHHS) and the Hip Outcome Scores (HOS) subscales for activities of daily living (ADL) and sport (HOS Sport). In addition, sport played, return to sport rates, and Tegner Scores were measured preinjury and postoperatively. Descriptive statistics were used to present demographic data. A priori analysis was used to determine the sample size needed to show minimal clinically important differences for mHHS, HOS ADL, and HOS Sport. Results: The study population included 50 patients with a mean age of 17.8 years. Athletes returned to sport at a rate of 92% (46/50). At a mean follow-up of 34 months, the mean mHHS, HOS ADL, and HOS Sport outcome scores were 85, 91, and 80 for the entire study group; 87, 92, and 84 for the group that returned to sport; and 67, 82, and 41 for the group that did not return to sport, respectively. Median preinjury and postoperative Tegner levels were 8 and 7, respectively. Labral takedown and reattachment was associated with lower HOS ADL (P = .01) and HOS Sport scores (P = .02). Conclusions: Athletes returned to sport at a high rate (92%; 46/50) after hip arthroscopy and perform activities at near preinjury levels. In this group of athletes, arthroscopic labral repair with chondrolabral preservation, which reflected less severe chondrolabral pathology, performed better than labral repair with takedown and reattachment.
