We have investigated the results of primary total hip arthroplasty (THA) performed in patients with developmental dysplasia of the hip (DDH). Through the New Zealand Joint Registry, we identified all patients with DDH undergoing primary THA (n = 1205) and all patients with primary osteoarthritis (OA) undergoing primary THA (n = 40 589) between January 1, 1999, and December 31, 2008. Postoperative outcomes, baseline information, and operative characteristics were analyzed and compared between the DDH and the OA groups. There was no significant difference in Oxford Hip Score or revision rate between the 2 groups. Our results support THA as a successful surgical option in the management of degenerative arthritis in DDH, with comparable functional outcomes and revision rates to THA performed for primary OA.
