Return-to-Sport Rates After Hip Arthroscopy for Femoroacetabular Impingement Syndrome in Flexibility Sports Athletes: A Systematic Review.

Abstract

Femoroacetabular impingement syndrome (FAIS) is a common cause of hip pain in young adults. Flexibility athletes represent an interesting subset due to the extreme range of motion requirements of their sport. The objective of this review was to provide a summary of the outcomes of hip arthroscopy for FAIS in patients who participate in flexibility sports. Three online databases (Medline, Embase, and PubMed) were searched from database inception (1946, 1974, and 1966, respectively) to January 10, 2023. Studies were screened for literature addressing surgical outcomes for flexibility athletes undergoing hip arthroscopy for FAIS. Systematic review. Level 4. Various patient-reported outcomes that evaluated the efficacy of hip arthroscopy in this patient population were abstracted and presented in descriptive and analytical format. Abstraction was performed by 2 reviewers. Overall, a total of 8 Level 3 or 4 studies and 295 patients (312 hips) were included in this review. The pooled standardized mean differences for the Visual Analog Scale for pain score, Modified Harris Hip Score, Hip Outcome Score - Activity of Daily Living scale, and Hip Outcome Score - Sport-Specific Subscale all demonstrated significant improvement after undergoing arthroscopy for FAIS between 12 and 116 months (N = 175, -1.97, 95% CI -2.5 to -1.4, P < 0.01, I2 = 76%; N = 211, 1.82, 95% CI 1.49 to 2.16, P < 0.01, I2 = 52%; N = 164, 1.75, 95% CI 1.42 to 2.05, P < 0.01, I2 = 28%; N = 211, 1.71, 95% CI 1.38 to 2.04, P < 0.01, I2 = 52%, respectively). Across 289 patients, 75.6% to 98% returned to sport at a similar or higher level than presurgery. This review demonstrates a trend of improvement in patient-reported pain, function, quality of life, and return to sport at a minimum of 12 months among flexibility athletes after hip arthroscopy to treat FAIS.
