Hip Arthroscopy (HA)
Periacetabular Osteootmy (PAO)
This approach addresses intraarticular pathology in the form of labral tears and cartilage that are often concomitant with DDH 3. Furthermore, capsular plication can be performed through HA to reduce instability of the joint.
The Bernese periacetabular osteotomy (PAO) remains the gold standard for treatment of symptomatic developmental dysplasia of the hip (DDH) in most patients with closed triradiate cartilage. First developed by Ganz in 1984, this technique utilizes 4 osteotomies to completely mobilize the acetabular fragment 1. Although a technically demanding procedure, it allows optimal correction in all planes and maintains integrity of the posterior column, enabling early weight bearing and mobilization.
