Endoscopic Shelf Acetabuloplasty Combined With Labral Repair, Cam Osteochondroplasty, and Capsular Plication for Treating Developmental Hip Dysplasia

Abstract

In addition to the underlying shallow acetabular deformity, a patient with hip dysplasia has a greater risk of development of a labral tear, a cam lesion, and capsular laxity. This combination of abnormalities exacerbates joint instability, ultimately leading to osteoarthritis. Unsurprisingly, only repairing the acetabular labrum remains controversial, and the outcome is unpredictable. In this technical note, with video, we demonstrate an entirely endoscopic approach for simultaneously repairing the most common mechanical abnormalities found in moderate hip dysplasia: labral repair, cam osteochondroplasty, capsular plication, and shelf acetabuloplasty using an autologous iliac bone graft.
