Background: Predictors of outcomes in adolescent athletes undergoing hip arthroscopy have not been established. The purpose of this study was to identify factors correlated with achieving the Patient Acceptable Symptomatic State (PASS) for the Hip Outcome Score-Sports Specific Subscale (HOS-SSS) at a minimum 5-year follow-up in adolescent athletes undergoing primary hip arthroscopy., Methods: Data were reviewed on adolescent (below 18 y old) athletes who underwent primary hip arthroscopy for femoroacetabular impingement syndrome between March 2008 and October 2015. Patients were included if they participated in sport within 1 year before surgery and had preoperative, 2-year, and minimum 5-year postoperative patient-reported outcome (PRO) scores for the modified Harris Hip Score, HOS-SSS, Visual Analog Scale for pain (VAS), and Non-Arthritic Hip Score (NAHS). Patients were divided into 2 groups based on whether they achieved PASS for HOS-SSS. Demographics, intraoperative findings, radiographic variables, surgical treatments, and PRO were compared. Multivariate logistic regression with corresponding odds ratios (ORs) quantified the correlation between variables and achievement of the PASS., Results: A total of 123 athletes with a mean age of 16.2±1.1 years were included. These athletes demonstrated significant imrpovement from preoperative to minimum 5-year follow-up for all recorded PROs (P<0.001). The multivariate logistic regression model identified preoperative NAHS (P=0.019, OR: 1.033), 2-year postoperative HOS-SSS (P=0.014, OR: 1.037), and 2-year postoperative VAS (P=0.003, OR: 0.590) as statistically significantly correlated with achieving the PASS. Athletes with a 2-year postoperative VAS pain score ≤2 achieved PASS at a rate of 81.9%, while those with a score >2 achieved PASS at a rate of 24.1% (P<0.001, OR: 14.2, 95% confidence interval: 5.23-38.7)., Conclusions: Favorable outcome were achieved at mid-term follow-up in adolescent athletes undergoing primary hip arthroscopy. Preoperative NAHS, 2-year postoperative HOS-SSS, and 2-year postoperative VAS pain scores were correlated with achieving the PASS for HOS-SSS at a minimum 5-year follow-up. Patients with 2-year postoperative VAS ≤2 were significantly more likely to achieve the PASS at 5-year follow-up than those with scores >2., Level of Evidence: Level III-case-control study., Competing Interests: B.G.D. reports grants and other from American Orthopedic Foundation, during the conduct of the study; personal fees from Adventist Hinsdale Hospital; personal fees and nonfinancial support from Amplitude; grants, personal fees, and nonfinancial support from Arthrex; personal fees and nonfinancial support from DJO Global; grants from Kaufman Foundation; grants, personal fees, nonfinancial support from Medacta; grants, personal fees, nonfinancial support, and other from Pacira Pharmaceuticals; grants, personal fees, nonfinancial support, and other from Stryker; grants from Breg; personal fees from Orthomerica; grants, personal fees, nonfinancial support, and other from Mako Surgical Corp.; grants and nonfinancial support from Medwest Associates; grants from ATI Physical Therapy; grants, personal fees, and nonfinancial support from St. Alexius Medical Center; grants from Ossur, outside the submitted work.

Background: Labral repair is generally preferred when facing labral tears. When an irreparable labral tear in the context of femoroacetabular impingement syndrome is present, arthroscopic labral reconstruction has been proven to be a valid option for labral restoration. However, data on this procedure for the adolescent population is scarce. The purpose of the present study was to report minimum 2-year follow-up patient-reported outcome measures (PROMs) on adolescents and young adults following arthroscopic acetabular labral reconstruction., Methods: Data were prospectively collected and retrospectively reviewed on adolescents and young adults who underwent hip arthroscopy between March 2009 and June 2018. Inclusion criteria were labral reconstruction, baseline and minimum 2-year follow-up PROMs. Patients were excluded if they were unwilling to participate in the study, had Tönnis grade >1, or dysplasia., Results: Twenty-three hips (22 patients) that underwent labral reconstruction were included. Ten hips (10 patients) underwent primary labral reconstruction, and 13 hips (12 patients) underwent revision reconstruction. The mean age was 19.3 years and 56.5% of patients were males. All patients improved significantly at minimum 2 years for all PROMs (P<0.001) with high satisfaction. Patients in both groups demonstrated improvement for all PROMs, patient satisfaction, and a rate of achieving the minimal clinically important difference., Conclusion: Arthroscopic labral reconstruction in adolescents and young adults demonstrated significant improvement and high patient satisfaction at minimum 2-year follow-up in the setting of irreparable labral tear. Favorable outcomes, high patient satisfaction, and high achievement rate for the minimal clinically important difference were obtained following labral reconstruction in this population the primary and revision scenarios., Level of Evidence: Level IV, case-series., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2021 Wolters Kluwer Health, Inc.
