Abstract
Objectives:
To report 5-year minimum outcomes of adolescents undergoing hip arthroscopy with labral reconstruction (RC) and compare their results to a control group of labral repairs (SR).
Methods:
Data was retrospectively reviewed from 2010 to 2018 for patients who underwent hip arthroscopy as treatment for FAI and labral tears. Patients were included if they were adolescents and had pre- and 5-year minimum postoperative patient-reported outcomes (PROs). Patients were included in the study group if they received labral reconstruction, and were propensity matched to a control group of patients who received labral repairs in a 1:2 ratio based on age, sex, BMI, and Tonnis Grade. PROs, rates of meeting clinically relevant thresholds, and rates of secondary procedures were compared between the groups.
Results:
Sixty-six hips were included in the study, the mean age of RC and SR group being 19.56 ± 2.03 and 19.57 ± 2.00 years. Significant and comparable magnitudes of improvement were seen across all PROs in both groups. The RC group reached lower postoperative scores across all PROs and had lower patient satisfaction at minimum 5-year follow-up (p < 0.01). No deteriorations in PROs between the 2 and 5 years time points were observed. The RC group met PASS for mHHS and MOI for NAHS and HOS-SSS at lower rates (p < 0.05). Furthermore, RC hips underwent revision arthroscopy at higher rates than SRs (31.82% vs. 2.27%; p < 0.01).
Conclusions:
Adolescents undergoing labral reconstruction showed favorable outcomes at 5-year minimum follow-up. However when compared to a propensity-matched SR group, RC hips reached lower postoperative PRO and satisfaction scores and met clinically relevant hip arthroscopy thresholds at lower rates. Moreover, RCs faced a 14-fold increased relative risk for revision arthroscopy compared to the control group.
