Abstract
Arthroscopic labral repair has been shown to result in favorable short- and midterm outcomes; however, the durability of outcomes specifically in older patients remains underreported. To (1) report prospectively collected hip preservation rates and patient-reported outcome measures (PROMs) at a minimum 10-year follow-up in patients aged ≥40 years after primary hip arthroscopy with labral repair and (2) perform a matched analysis comparing patients aged ≥40 years with patients aged <40 years. Cohort study; Level of evidence, 3. Data were prospectively collected and retrospectively reviewed on all patients who underwent primary hip arthroscopy between February 2008 and December 2011. Patients aged ≥40 years who underwent labral repair were included. Preoperative and minimum 10-year follow-up scores were collected for multiple PROMs. Propensity score matching was utilized to compare these patients with a cohort of patients <40 years. Of the 113 hips eligible, 91 hips (80.5%) on 85 patients (6 bilateral) had a minimum 10-year follow-up. There were 58 women (68%) and 27 men (32%) with a mean age and body mass index of 47.8 years and 25.8, respectively. The hip preservation rate for patients aged ≥40 years was 78%, with 20 patients requiring arthroplasty during the study period. There was significant improvement in all PROMs from baseline to minimum 10-year follow-up with high rates of achieving the minimal clinically important difference and Patient Acceptable Symptom State clinical outcome thresholds. In total, 69 patients aged ≥40 years were propensity matched to 107 patients <40 years. Patients ≥40 tended to have a lower hip preservation rate (81.2% vs 91.6%; P = .06), while patients in the younger cohort had significantly higher rates of secondary hip arthroscopy (14% vs 3%; P = .02). Improvement in PROMs was comparable between the groups. Patients ≥40 years who underwent primary hip arthroscopy with labral repair demonstrated a hip preservation rate of 78%, significant and durable improvement in PROMs, and high rates of satisfaction at a minimum 10-year follow-up. Matched analysis with patients <40 years revealed comparable improvement in patient-reported outcomes between the 2 groups, with a tendency to a higher level of arthroplasty in patients ≥40 years.
