(A) A preoperative radiograph shows the hips of a 29-year-old woman with activity-related right hip pain. She was diagnosed with Legg-Calvé-Perthes disease at the age of 14 years. She was treated with surgical dislocation and osteochondroplasty. After this portion of the procedure, the hip was examined and was thought to be unstable. A PAO was performed during the same surgical setting. (B) Two years after surgery, the patient has excellent results and no restriction of activity.
