The Clayton total hip arthroplasty. A ten-year follow-up study.

Early success has been reported using a long-stem cemented femoral component in total hip arthroplasty (THA). The same patient group reported by the authors' institution at five years were reviewed again at ten years postarthroplasty. Certain trends can now be defined, including gradual deterioration in the Harris hip score, tendency toward failure of acetabular fixation (8.4% loosening rate requiring revision), and increased calcar resorption. Overall, the cemented femoral component has performed admirably, with a 97% success rate at ten-years' post-THA (3.1% revision rate). In this study, success was defined as arthroplasties that did not require revision. Ninety percent of observed patients were rated as good or excellent using the Harris hip score. The Clayton femoral component provides excellent durability by virtue of design.
