EP8.98 Predictive Value of Pre-Operative Patient-Reported Outcomes for Time to Return to Sport Clearance after Hip Arthroscopy in Division I Collegiate Athletes

Abstract Purpose To determine the relationship between preoperative and early postoperative (3-month) PROs and time to RTS clearance following hip arthroscopy for FAI in NCAA Division I collegiate athletes. Methods Routinely collected health and performance data were retrospectively reviewed of Division I collegiate athletes who underwent hip arthroscopy for FAI at a single institution between January 2017 and July 2024. Athletes completed PROs, including: the modified Harris Hip Score (mHHS), iHOT-12, Hip Outcome Score (HOS), Copenhagen Hip and Groin Outcome Score (HAGOS), PROMIS domains, Veterans RAND-12 (VR-12), and Tampa Scale for Kinesiophobia (TSK-11). Athletes were excluded if they lacked pre-operative or 3-month post-operative PROs, had no intention to return to sport pre-operatively, or underwent lower extremity surgery within 6 months prior to hip arthroscopy. RTS clearance was defined as the date the medical team provided clearance for unrestricted sport activity. Time-to-event Cox proportional hazards models evaluated associations between PROs (pre- and 3 months post-hip arthroscopy) and time to RTS clearance. Results Fifty-four division I athletes (24 female; mean age, 21.0 ± 1.3 years) were included; 47 had a documented RTS date, with a median time to RTS clearance of 4.35 months (IQR, 3.57–5.39). Better pre-operative HAGOS Quality of Life (QOL) and Activities of Daily Living (ADL) scores were associated with quicker time to RTS clearance (QOL: HR [95% confidence interval] = 1.04 [1.02–1.07], p<0.01; ADL: 1.03 [1.00–1.04], p=0.02). No other pre-operative or 3-month post-operative PROs were associated with time to RTS clearance. Conclusions Better pre-operative HAGOS ADL and QOL scores predict quicker time to RTS clearance in collegiate athletes undergoing hip arthroscopy for FAI, suggesting that baseline daily function and well-being may influence recovery trajectory. These findings highlight the potential value of HAGOS subscales in guiding individualized RTS counseling in elite athletic populations.
