Total hip arthroplasty after failed intertrochanteric valgus osteotomy foradvanced osteoarthrosis

Thirty hips that had undergone conversion total hip arthroplasty because of failed intertrochanteric valgus osteotomy for advanced osteoarthrosis were analyzed clinically and radiographically for more than 2 years, The averag e followup after total hip arthroplasty was 7 years (range, 2-18 years). Th e average age of the patients at the time of valgus osteotomy was 42 years (range, 30-63 years), The average age of the patients at the time of conver sion total hip arthroplasty was 57 years (range, 43-76 years), and the aver age period between valgus osteotomy and conversion was 14 years (range, 3-2 4 years). Perioperative complications in conversion total hip arthroplastie s were minimal, and intramedullary reaming was performed easily. Of the 30 conversion total hip arthroplasties, 12 cemented and 18 cementless componen ts were used, respectively. Kaplan-Meier's survival analysis indicated that survivorship of cemented stems was significantly higher than that of conve ntional cementless stems. Cemented stems are preferable for conversion tota l hip arthroplasty after failed femoral valgus osteotomy.
