Return to Sport After Primary Hip Arthroscopic Surgery and Labral Repair in Female Athletes With Femoroacetabular Impingement: A Minimum 5-Year Follow-up

Abstract

Background: Femoroacetabular impingement (FAI) is a common cause of hip pain in female athletes. There are limited data on midterm outcomes for female athletes undergoing hip arthroscopic surgery. Purpose: To evaluate return-to-sport rates and clinical outcomes in female athletes with FAI after primary hip arthroscopic surgery with labral repair and femoral osteochondroplasty. Study Design: Case series; Level of evidence, 4. Methods: A retrospective analysis of a single institution’s database was performed to identify female athletes who underwent primary hip arthroscopic surgery with labral repair and femoral osteochondroplasty from July 2011 to October 2019 with a minimum 5-year follow-up. Preoperative radiographs were evaluated for the lateral center-edge angle, Tonnis angle, Tonnis grade, and alpha angle. Patient-reported outcome measure (PROM) scores, including those for the modified Harris Hip Score, Hip Outcome Score, Tegner Activity Scale, and visual analog scale for pain, as well as patient satisfaction with surgery were analyzed postoperatively. Results: A total of 63 hips (27 left, 36 right) in 56 female patients (mean age, 21.6 ± 8.0 years; mean body mass index, 24.7 ± 4.8 kg/m2) were included and followed for a mean of 8.4 ± 2.1 years (range, 5.0-13.2 years). Preoperatively, patients participated in basketball (n = 18), dance (n = 21), hockey (n = 8), and soccer (n = 12). Of the 56 patients, 41 attempted to return to sport. There were 28 (68%) female athletes who successfully returned to their preoperative sport. Of the total cohort, 21 (38%) patients cited non–hip-related factors for discontinuing their sport. All postoperative PROM scores improved significantly compared with preoperatively (P ≤ .002) for patients with available preoperative data. Those who returned to sport had significantly improved Hip Outcome Score values compared with those who did not return to sport (P ≤ .010). Conclusion: Female athletes who underwent primary hip arthroscopic surgery for FAI had significant improvements in PROM scores and moderate return-to-sport rates at a minimum 5-year follow-up. Most athletes discontinued sports because of non–hip-related factors, although hip-related issues were also cited. Our analysis highlights the need for thorough perioperative counseling and establishing appropriate patient expectations for female athletes before hip arthroscopic surgery.
