Patient-Reported Outcomes of Capsular Repair Versus Capsulotomy in Patients Undergoing Hip Arthroscopy: Minimum 5-Year Follow-up-A Matched Comparison Study.

Abstract: To elucidate whether capsular closure during hip arthroscopy affected patient outcomes over midterm follow-up.

Methods: Between 2008 and 2011, data were prospectively collected and retrospectively reviewed on patients who underwent hip arthroscopy. Patients were then matched for age, gender, worker's compensation, body mass index, and acetabular coverage. The inclusion criteria were capsular repair or unrepaired capsulotomy, lateral-center edge angle ≥18°, and minimum 5-year follow-up. The exclusion criteria were previous hip surgery or conditions and Tönnis grade >1. Patient-reported outcome scores (PROs) included modified Harris hip score (mHHS), nonarthritic hip score, hip outcome score sport-specific subscale, and visual analog score for pain, which were collected preoperatively, at 3 months, and annually thereafter. Minimal clinical important difference (MCID) and patient acceptable symptomatic state (PASS) for both groups were analyzed. Patient satisfaction was noted as well as any complications, secondary surgery, and conversion to arthroplasty.
