Minimum 10Year Outcomes of Hip Arthroscopy With Retroverted Acetabulum

Prospectively collected data were retrospectively reviewed for patients who underwent hip arthroscopy for FAIS and labral tear treatment between February 2008 and November 2013 with acetabular retroversion. On a well-positioned anteroposterior pelvic radiograph, retroversion was based on the presence of an ischial spine sign in addition to either a crossover over 20% or posterior wall sign. Preoperative and minimum 10-year follow-up for the modified Harris Hip Score (mHHS), Non-Arthritic Hip Score (NAHS), Hip Outcome Score-Sports Specific Subscale (HOS-SSS), Visual Analog Scale (VAS) for pain, International Hip Outcome Tool (iHOT-12), and Patient Satisfaction scores were collected. Rates of achieving the minimal clinically important difference (MCID) and the patient acceptable symptomatic state (PASS), as well as hip joint survival from conversion to total hip arthroplasty (THA) and the number of hips undergoing ipsilateral revision hip arthroscopy were reported.
