Open Periacetabular Osteotomy

What is a Periacetabular Osteotomy?

Periacetabular Osteotomy (PAO) is a surgical procedure which involves reorienting the acetabulum, or
socket portion, of the hip joint within the pelvis. The goal is to improve the structural properties of the
hip joint by increasing the surface area of cartilage in the weight bearing portion of the hip.
