110 Müller total hip replacements (THR) were performed in 90 patients between July, 1974 and April, 1980. Twenty-one patients with 26 arthroplasties had been revised for various reasons. Seventeen patients had died and 20 patients were lost to follow-up.
The remaining 32 patients with 38 arthroplasties were reviewed minimum of ten-years post-operatively. The average JOA score was 66 points (range, 51 to 94).
Follow-up radiographs showed a 57.9 per cent incidence of loosening of the acetabular component and a 15.8 per cent incidence of the femoral component according to Nagaya's x-ray assessment.
