Introduction: There is a paucity of literature on mid-term outcomes for hip arthroscopy for femoroacetabular impingement and labral tears.
Methods: Inclusion criteria were age at surgery <50 years and documented preoperative patient-reported outcomes. Patients with a Tönnis grade >0 or previous ipsilateral hip conditions were excluded.
Results: Of 407 eligible cases, 327 hips (295 patients) had minimum 5-year follow-up. Mean age was 32.4 years. All mean patient-reported outcomes and visual analog scale improved at follow-up (P < 0.001). Mean satisfaction was 7.9. Thirty-eight hips (11.6%) required secondary arthroscopy at a mean of 25.1 months. Survivorship at minimum 5 years was 92.4%. The complication rate was 7.0%.
Conclusions: Hip arthroscopy for management of femoroacetabular impingement and labral tears in patients aged <50 demonstrates favorable and safe mid-term outcomes. Several risk factors for conversion to total hip arthroplasty in this age group warrant cautious patient selection for arthroscopy.
