Detailed Description

Even though the PAO is applied worldwide and is the preferred joint preserving treatment some issues remains unclear and controversial. One is the exact indication for surgery and risk factors for early failure of the procedure. The is a retrospective cohort study assessing pre- and postoperative radiographic indices of hip dysplasia in order to identify factors predicting failure following PAO. The minimum duration of follow-up is 2 years. Failure following PAO is defined by a WOMAC pain score > 10 or the insertion of a total hip arthroplasty.
