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.
1983年1月至1984年7月期间，一名外科医生使用Mittelmeier无骨水泥陶瓷假体，为骨关节炎或骨坏死患者连续实施了112例初次全髋关节置换术。其中93例髋关节接受了前瞻性随访，最短随访时间为60个月，中位随访时间为108个月。有5例（5.4%）髋关节因松动而进行了翻修。在其余髋关节中，77例（87.5%）临床评定结果令人满意。以翻修为终点的累积生存概率估计在5年时为92.7%，在10年时为87.9%。然而，髋臼杯的总体机械故障率为21.5%，股骨柄为22.6%。未观察到股骨或髋臼骨溶解病例。
