We previously reported the 9-year follow-up results of 121 cementless total hip arthroplasties (THAs) from 1990 to 1994 in 93 patients with developmental dysplasia of the hip (DDH). The present study reports the updated long-term results after a mean follow-up of 23 years. Fifty-seven patients (72 hips) were alive and available for follow-up. Since our previous report, nine THAs had been revised. The cumulative implant survivorship of any component was 87% (95% CI, 78-92%). The cumulative probability of not having aseptic cup loosening was 87% (95% CI, 77-93%) and there was no revision surgery for aseptic stem loosening. In three hips (5%), an exchange of the ball and liner due to polyethylene wear was performed after a mean of 12 years. This study demonstrates that cementless THA for DDH with restoration of the hip joint center provides excellent long-term durability.
我们之前报告了1990年至1994年间93例发育性髋关节发育不良（DDH）患者接受的121例非骨水泥型全髋关节置换术（THA）的9年随访结果。本研究报告了平均随访23年后的最新长期结果。57例患者（72髋）存活且可供随访。自我们之前的报告以来，有9例THA进行了翻修。任何组件的累积植入物存活率为87%（95%CI，78-92%）。无无菌性髋臼松动的累积概率为87%（95%CI，77-93%），且没有因无菌性股骨柄松动而进行的翻修手术。在3髋（5%）中，平均12年后因聚乙烯磨损进行了球头和衬垫的更换。本研究表明，非骨水泥型THA用于DDH并恢复髋关节中心可提供出色的长期耐用性。
