Arthroscopic Capsular Plication and Labral Seal Restoration in Borderline Hip Dysplasia: 2-Year Clinical Outcomes in 55 Cases.
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.
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
