Kyin C, Maldonado DR, Go CC, et al. - This study was undertaken to investigate mid to long-term patient-reported outcomes (PROs) of hip arthroscopy as well as the rates of secondary surgery and to distinguish indications for surgery and noted predictors of failure. Researchers conducted a systematic review of the current literature with the terms “hip arthroscopy,” outcomes,” “patient-reported outcomes,” “mid-term,” “5-year,” “long-term,” and “10-year” in the PubMed, Cochrane, and Embase databases in April of 2020 according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. They included 13 articles involving a total of 1,571 hips, and the average follow-up time ranged from 60 to 240 months. Patients who underwent primary hip arthroscopy demonstrated improvement in several PROs at mid to long-term follow-up. The data demonstrated that there was great variability in rates for revision surgery and conversion to total hip arthroplasty. For hip arthroscopy, the most common indications were labral tears and femoroacetabular impingement syndrome. For unfavorable outcomes, osteoarthritis and elevated age were the most cited predictors.
