To present minimum 2-year patient-reported outcomes (PROs) and return to sport (RTS) data for a population of basketball players after hip arthroscopy. Data were prospectively collected and retrospectively reviewed for all patients who underwent hip arthroscopy between February 2009 and May 2014. Patients with preoperative and minimum 2-year postoperative PROs, visual analog scale score for pain, and satisfaction, who regularly played basketball within 1 year before surgery, and who attempted to RTS met the inclusion criteria. Exclusion criteria were previous ipsilateral hip surgery or conditions such as fracture, dysplasia, or femoral avascular necrosis. Patients were matched 1:1 to a control group composed of those who did not play any sports before surgery, based on the following matching criteria: age ±5 years, sex, and body mass index ±5. Statistical analysis was performed to determine significant differences in PROs. Conversion to total hip arthroplasty (THA) was considered an endpoint. Thirty-one patients (81.6%) met inclusion criteria with follow-up of 46.8 ± 20.6 months. The mean age was 30.0 ± 12.3, and the mean body mass index was 26.3 ± 6.5. Male patients (64.5%) outnumbered female patients (35.5%). A majority of the players (54.8%) identified themselves as recreational athletes; the remainder competed at the high school, collegiate, amateur, or professional level. There was significant (P < .001) improvement in all PRO measures and visual-analog scale scores from baseline to a minimum 2-year follow-up. At the most recent follow-up, mean patient satisfaction was 8.1 ± 2.1. Twenty-two (78.6%), and 23 patients (82.1%) achieved the patient acceptable symptom state on the modified Harris Hip Score and the Hip Outcomes Score-Sports Specific Subscale. Twenty-one (75.0%) and 17 (60.7%) patients had a minimal clinically important difference on the modified Harris Hip Score and the Hip Outcomes Score-Sports Specific Subscale, respectively. Three patients (9.7%) with an average age of 47.5 (P = .023) converted to THA at a mean of 35.9 ± 7.2 (range 29.66-43.75) months after arthroscopy. At the most recent follow-up, the RTS rate was 83.9%. Subjective ability level was the same or higher in 23 patients (74.2%). Hip arthroscopy in basketball athletes demonstrates a significant increase in PROs, a high RTS rate, and a low risk of complications. Hip arthroscopy may be considered in basketball players <40 years old for whom nonoperative treatment fails and who have a significantly limited level of play. Careful patient selection and counseling should be used when considering hip arthroscopy in basketball players >40 years old because there may be a high rate of conversion to THA. Level III, retrospective comparative study.
