A ten-year follow-up study of 170 Charnley total hip arthroplasties.

Between 1971 and 1974, 352 low-friction hip arthroplasties were performed on 296 patients using the precise Charnley technique. One hundred seventy hips in 145 patients were followed either for ten years or to the point at which revision of the total hip arthroplasty was made necessary by infection, aseptic loosening, chronic dislocation, or similar complications. The results of this evaluation revealed an overall revision rate to the ten-year level of 8.8% in 171 hips and an infection rate of 1.4% for all 352 cases. Both clinical and radiologic assessments encourage further use of this technique.
