From 1979 to 1984, 126 consecutive Total Condylar (Howmedica, Rutherford, NJ) knee arthroplasties were performed at a hospital in Taiwan, of which 64 knees were available for evaluation. The patients' average weight was 58 kg. The average Hospital for Special Surgery knee score at the latest follow-up was 86 points. Using revision for mechanical failure as an end point, the 20-year overall survival was 91.9%. The survival for the all-polyethylene tibial component was 96.4% and for the metal-backed tibial component was 88.4%. The difference was statistically significant (P < .001). We recommend the use of the more cost-effective and durable all-polyethylene tibial component for a primary cemented total knee arthroplasty, particularly in Asians with a relatively low weight and who are relatively inactive, especially in elderly people.
1979年至1984年期间，台湾一家医院连续进行了126例全髁型（Howmedica公司，新泽西州卢瑟福）膝关节置换术，其中64例膝关节可供评估。患者平均体重为58千克。在最近一次随访时，特殊外科医院膝关节评分的平均值为86分。以因机械故障进行翻修作为终点，20年的总体生存率为91.9%。全聚乙烯胫骨组件的生存率为96.4%，金属背衬胫骨组件的生存率为88.4%。差异具有统计学意义（P < 0.001）。我们建议，对于初次骨水泥型全膝关节置换术，尤其是体重相对较轻且活动较少的亚洲人，特别是老年人，应使用成本效益更高且更耐用的全聚乙烯胫骨组件。
