OBJECTIVE

The objective of this review was to analyze the effect of arthroscopic surgery for femoroacetabular impingement syndrome (FAI) in adolescents and factors that may influence the revision rate.

DESIGN

Systematic review and meta-analysis.

SETTING

PubMed, Scopus, Cochrane Library, EMBASE, and MEDLINE were searched from their earliest records to May 2021.

PATIENTS

Adolescents who underwent primary arthroscopic treatment for FAI.

INTERVENTIONS

Hip arthroscopic treatment.

MAIN OUTCOME MEASURES

Patient-reported outcomes (PROs), alpha angle, revision rates, and the rate of complications.

RESULTS

A total of 832 hips in 753 patients were included in this study. All PROs improved significantly. The modified Harris Hip Score pooled mean difference was 24.99 (95% CI, 22.88-27.10, P < 0.0001, I2 = 19.9%), Hip Outcome Score (HOS)-Sports-Specific Subscale was 35.88 (95% CI, 33.07-38.68, P < 0.0001, I2 = 0%), HOS-Activities of Daily Living was 23.53 (95% CI, 21.21-25.85, P < 0.0001, I2 = 0%), and the Nonarthritic Hip Score was 22.34 (95% CI, 18.40-26.28, P < 0.0001, I2 = 40.9%). The visual analog scale for pain decreased by 40.39 (44.39-36.40, P < 0.0001, I2 = 0%). The alpha angle decreased by 22.0 degrees from 62.9 degrees to 40.9 degrees after arthroscopic surgery. The rate of complication and revision surgery was 1.2% (10/832) and 3.4% (28/832), respectively, with high postoperative patient satisfaction.

CONCLUSIONS

All PROs significantly improved after surgery, with a low rate of complications and reoperation. High postoperative patient satisfaction was also reported.
