Periacetabular Osteotomy (PAO)

Periacetabular osteotomy is a surgery used to correct hip dysplasia or acetabular dysplasia. The acetabulum (hip socket) is repositioned to cover more of the femoral head to improve stability of the hip joint. The surgery involves cutting the pelvis around the entire acetabulum, which is then repositioned so it better covers the femoral head.


Physical therapy will begin the day after surgery and starts with range-of-motion exercises. Most patients also use crutches for the first two months after surgery.
