Extensive Capsule-Labrum Adhesion: A Potential Risk Factor for Continuous Symptom and Worse Patient-Reported Outcomes in Patients With Femoroacetabular Impingement Syndrome With Labrum Tear After Arthroscopy.

Background: Capsule-labrum adhesions are a common complication of hip arthroscopy surgery. However, their effects on patient outcomes are poorly understood. Purpose: To examine the effect of capsular adhesions on outcomes in patients undergoing hip arthroscopy for treatment of femoroacetabular impingement with labrum tear. Study Design: Cross-sectional study; Level of evidence, 3. Methods: We retrospectively examined 65 adult patients (67 hips) with a diagnosis of femoroacetabular impingement syndrome (FAIS) with labral tear (LT) who underwent hip arthroscopy. All were followed for at least 2 years. Patients were divided into symptomatic and asymptomatic groups. All patients underwent physical examination and magnetic resonance imaging of the hip at the last follow-up. Patients were also divided into 3 groups based on capsule-labrum adhesion length to further explore the association between adhesions and patient-reported outcomes (PROs). Results: A total of 65 patients (67 hips) were analyzed, with 29 hips allocated to the symptomatic group and 38 to the asymptomatic group. The mean age was 44.39 years, and the mean follow-up time was 56 months. Patient characteristics were mostly similar between the 2 groups ( Conclusion: Postoperative capsule-labrum adhesions were highly prevalent among patients treated with hip arthroscopy under interportal capsulotomy without capsular repair for FAIS with LT. In this cohort, more extensive capsule-labrum adhesions were associated with persistent symptoms and worse PROs.
