title: Primary total hip arthroplasty with an uncemented femoral component five- to nine-year results.
abstract: This study reports the outcome of total hip arthroplasty with use of an uncemented, tapered stem with a 5- to 9-year follow-up. The first 200 consecutive patients (214 hips) undergoing total hip arthroplasty with the Accolade TMZF stem (Stryker Orthopaedics, Mahwah, NJ) were enrolled prospectively. Follow-up for these patients averaged 7.6 years and encompassed review of clinical records as well as review of serial anteroposterior and lateral radiographs. There were 5 revision surgeries for aseptic loosening, 2 cases of infection, instability, and polyethylene wear. Our failure rate, defined as hips needing revision, was 2.6%, and the failure rate due to aseptic loosening of the femoral component was 0.6%. These results demonstrate the high success rate of this implant providing support for its continued use.
