What is the utility of hip arthroscopy in patients with joint laxity? A contemporary systematic review of patient-reported and surgical outcomes.

Introduction: The purpose of this study was to systematically review the literature to understand the contemporary outcomes for patients with joint laxity managed with hip arthroscopy.

Materials And Methods: A search was performed utilizing the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Statement guidelines. All literature related to joint laxity in hip arthroscopy patients was identified. Inclusion criteria consisted of patient-reported outcomes and Beighton and Horan Joint Mobility Index scoring. Study quality was assessed using the Methodological Index of Non-Randomized Studies criteria.

Results: Seven articles were identified, including 412 patients (416 hips). Patients were predominantly female (range 83-100%). Mean patient age ranged from 13-69 years. Five studies consisting of 370 hips reported a range of 75 to 100% undergoing labral repair, 0 to 13% labral debridement, 0 to 7% labral reconstruction, 43 to 100% capsular closure, 94 to 99% femoroplasty, 3 to 80% rim resection, and 9 to 50% subspine decompression for surgical management. Post-operative follow-up range was 6-99 months. The mean range of improvement in Hip Outcomes Score Activities of Daily Living, Hip Outcomes Score-Sports Subscale, modified Harris Hip Score, Visual Analog Scale, and 12 item Short Form Health Survey were 17.6-31.3, 31.3-35.1, 22.5-53.8, - 2.79-8, and 12.4-16.9 respectively.

Conclusion: Generalized ligamentous laxity patients managed with hip arthroscopy were predominantly young women. At short-term follow-up, mean patient-reported outcomes were positive, with improvement postoperatively in activities of daily living, sports, and quality of life.
