Beck EC, Nwachuckwu BU, Jan K, et al. - The present study was undertaken to describe the rates of achieving clinically significant outcomes as defined by the minimal clinically important variation, patient acceptable symptomatic state, or substantial clinical benefit in adolescent patients and 2) the rates of clinical failure 5 years after undergoing hip arthroscopy for femoroacetabular impingement syndrome (FAIS). Between January 2012 and January 2015, researchers collected data from consecutive adolescent patients (defined by the American Academy of Pediatrics as age 11 to 21 years) who had undergone primary hip arthroscopy with routine capsular closure for the treatment of FAIS by a single, fellowship-trained surgeon. They recorded baseline data, clinical outcomes including Hip Outcome Score–Activities of Daily Living (HOS-ADL), HOS–Sports Subscale (HOS-SS), modified Harris hip score, international Hip Outcome Tool, and clinical failure rates at five-years postoperatively. A total of 85(60.4%) patients (85 hips) were enrolled in the final analysis out of the 139 eligible patients, with an age and body mass index average of 17.6 +2.5 years (range 13-21) and 22.3 +3.1 kg/m 2 respectively. This study’s findings indicated that a large majority (89.2%) of adolescent individuals undergoing primary arthroscopic treatment for symptomatic FAIS achieved meaningful clinically significant outcomes. Moreover, only 2.4% of individuals failed clinically, needing revision hip arthroscopy due to continued pain.
