Abstract: We followed 100 consecutive primary total hip replacements with a proximal hydroxyapatite coating for 10 years. No patient was lost to follow-up. 29 patients (32 hips) died before the 10-year follow-up was done; none of their hips had been revised. Thigh pain on activity occurred in 3 hips. We found no radiographic signs of loosening of the femoral components. In course of time the location of dense bone around the femoral stem, which would suggest implant/bone stress transfer, moved distally in 51 of 67 stems after 10 years. No linear or distal osteolysis occurred around the stem. Revision of 1 stem was performed because of thigh pain, but it was found fixed to bone proximally, while 3 cups were revised because of acetabular osteolysis. The 10-year survival of the stem and cup, using revision or pending revision as endpoint, was 100% (95% CI: 99-100) and 97% (95% CI: 94-99), respectively.
