Abstract
One hundred twelve consecutive primary total hip replacements were performed for osteoarthritis or osteonecrosis by a single surgeon using the Mittelmeier ceramic prosthesis without cement between January 1983 and July 1984. Ninety-three of these hips were followed prospectively to a minimum of 60 months and a median of 108 months. Five (5.4%) hips have been revised for loosening. Of the remaining hips, 77 (87.5%) were rated clinically satisfactory. Cumulative survival probability using revision as endpoint was estimated to be 92.7% at 5 years and 87.9% at 10 years. However, overall mechanical failure rates were 21.5% for the cup and 22.6% for the stem. There was no case of either femoral or acetabular osteolysis observed.
