Arthroscopic Capsular Plication and Labral Seal Restoration in Borderline Hip Dysplasia: 2-Year Clinical Outcomes in 55 Cases.
Abstract: To report clinical outcomes in patients with borderline dysplasia undergoing an arthroscopic technique of labral seal restoration with minimal acetabular rim resection and capsular plication.
Methods: Patients younger than 40 years with a lateral center-edge angle of 18° greater and 25° or less and 2-year follow-up after undergoing an arthroscopic technique of labral seal restoration with minimal rim resection (≤2 mm) and capsular plication (3-5 sutures placed in an oblique orientation to create an imbrication and inferior shift) were included. Patients underwent arthroscopy for symptoms that had marginal improvement with a minimum 6-week structured physical therapy program. Patients with a Tönnis grade of 1 or greater, a center-edge angle of 17° or less, and Legg-Calvé-Perthes disease were excluded. The following patient-reported outcomes (PROs) were recorded prospectively but retrospectively reviewed: modified Harris Hip Score, Non-Arthritic Hip Score, Hip Outcome Score-Sports-Specific Subscale, and Hip Outcome Score-Activities of Daily Living. The visual analog scale score, patient satisfaction score, complications, and revision procedures were also recorded
