Thirty one cases of rotational acetabular osteotomy (RAO) combined with femoral valgus osteotomy in our institute were retrospectively reviewed. The follow-up period was over 5 years. The original disease in all cases was osteoarthritis after hip dysplasia. Thirteen cases were pre/primary stage, 17 cases were advanced stage, and one end-stage.<BR>The radiological follow-up results showed that 20 osteoarthritic hips preserved their joint space, 10 had progress of osteoarthritic changes, but none had revision surgery including THA. Seven out of those ten cases progressed to end-stage and these cases were all bilateral cases. This study suggested the medialization of the femoral head is an essential part of this surgery and when this in done, the clinical results may be good. This surgery may expand the surgical indications for RAO in combination with femoral valgus osteotomy.
