Abstract A follow-up study of 15 (15-17) years of 320 consecutive Zweymuller total hip arthroplasties is presented. Age at surgery was 67 (29-99) years. A total of 164 (51.3%) patients had died. Clinical and radiological examinations were available for 97 (30.3%), phone interviews and radiological examinations for 4 (1.3%) hips, and phone follow-ups for 49 (15.3%). There were 6 (1.9%) patients who were lost to follow-up. The Harris Hip Score results in a median value of 88. According to the Kaplan-Meier method, a survival rate of the cup/inlay of 98% (95% confidence interval, 95%-99%) after 17 years was achieved. For the stem/head, the survival rate was 98% (95% confidence interval, 94%-99%). In 95.2% of patients, no operative revision was required. The rate of aseptic loosening was 2% for the acetabular and 1% for the femoral component.
