BACKGROUND: Characteristically, @entity2530 affects younger @entity1 who typically refer to the orthopedic surgeon for the first time in the third to fifth decades of life, in the late stages of the disease. Femoral metal-on-metal hip resurfacing is as an alternative to conventional total hip arthroplasty in treating @entity570 . Since there are already many reports regarding the successful outcome of resurfacing in advanced @entity571 , the purpose of this study was to analyze the clinical outcomes of this procedure in @entity1 with @entity2530 of the femoral head and to compare them with a matched group of @entity1 with @entity571 . MATERIAL/METHODS: This retrospective cohort study evaluated a consecutive series of 52 @entity1 with end-stage @entity2530 (28 @entity1 ) and @entity571 (24 @entity1 ) of the femoral head, managed by metal-on-metal hip resurfacing in a referral orthopedic center from Feb 2002 to May 2007. @entity158 , function and deformity were evaluated with the use of the Harris hip score after the operation. @entity1 were clinically followed for a mean of 41 months. RESULTS: The @entity1 in the @entity571 group had a significantly higher mean age than those in the @entity2530 group (47.88    12.6 vs 30.86    7.5, p=0.003). The clinical outcomes were similar for both groups. There was no significant difference in mean Harris hip score (p=0.347) and @entity572 (p=0.346) between @entity2530 and @entity571 groups after surgery. CONCLUSIONS: On the basis of these initial findings, we recommend MOM resurfacing as a viable treatment option for @entity1 with advanced stages of @entity2530 .
