Return-to-Sport Rates and Functional Outcomes After Hip Arthroscopy for Femoroacetabular Impingement in Young...

Frequent pivoting, rotation, and deep hip flexion place football players at high risk for femoroacetabular impingement (FAI), a leading cause of hip pain in this population. Previous studies have primarily focused on professional National Football League athletes undergoing mixed surgical techniques, including labral debridement. Limited data exist on outcomes in younger, amateur players treated with labral repair.

To report return to sport (RTS) rates and functional outcomes at a minimum 5-year follow-up in primarily active high school and college football players undergoing primary hip arthroscopy with labral repair for FAI.

Case series, Level of evidence, 4.

All football players who underwent primary hip arthroscopy with labral repair for FAI between 2010 and 2019 were identified from an institutional database. Collected data included descriptive data, radiographic parameters, surgical details, and reoperations. At a minimum 5-year follow-up, RTS outcomes and patient-reported outcome measures (PROMs), such as the Modified Harris Hip Score (mHHS) and Hip Outcome Score (HOS), were evaluated.

A total of 36 hips in 27 male athletes (mean age, 18 years; body mass index, 28.1 kg/m²) were included. The majority of athletes competed at the high school (70%) or collegiate level (26%). Mean preoperative radiographic measurements were as follows: lateral center-edge angle, 31.6°; Tönnis angle, 4.1°; and alpha angle, 61.4°. Femoroplasty and acetabuloplasty were performed in 100% and 86% of cases, respectively. Also, 84% of players returned to football, all at the same or higher level than before surgery. At a mean follow-up of 9.8 years, all PROMs improved significantly from baseline (P < .002). Outcome scores at follow-up were as follows: mHHS 90.5; HOS-Activities of Daily Living, 94.5; HOS-Sports-Specific Subscale, 91.1; and visual analog scale (VAS) pain with use, 2.3/10; VAS pain at rest, 1.3/10; and surgical satisfaction, 8.5/10. No patients required revision surgery. However, 2 patients (7%) underwent reoperations-including 1 for heterotopic ossification excision and 1 for periacetabular osteotomy.

American football players who underwent primary hip arthroscopy with labral repair for FAI achieved excellent long-term outcomes, with high RTS rates at the same or higher levels, and improvements in PROMs and patient satisfaction. Despite favorable outcomes, nonmedical factors, such as graduation, may influence RTS in competitive athletes, particularly at the high school and collegiate levels.
