Between January 1988 and December 2006, a total of 3014 primary total knee arthroplasties (TKAs) in 2042 patients were performed, and survivorship analysis was performed. Survivorship analysis showed a 10-year survival of 93.8% and a 20-year survival of 70.9%. There was no significant difference in the survival rate according to sex and diagnosis (P = .142 and .443, respectively). The survival rate was higher in the patients older than 60 years (P < .001). The survival rate of Total Condylar IV (TC-IV) was higher than that of Ortholoc (Dow Corning Wright Medical, Arlington, Tenn) (P < .001). Total knee arthroplasty results in satisfactory long-term survival rates. However, the survival rate decreases over time. The risk of requiring revision TKA was related to age and type of implants. Careful consideration is necessary to decide the time for TKA and select type of implants.
1988 年 1 月至 2006 年 12 月，共对 2042 例患者的 3014 例原发性全膝关节置换术（TKA）进行了随访分析。生存分析显示，10 年生存率为 93.8%，20 年生存率为 70.9%。性别和诊断对生存率无显著影响（P=0.142 和 0.443）。60 岁以上患者的生存率较高（P<0.001）。TC-IV 型的生存率高于 Ortholoc（陶氏化学公司，美国田纳西州阿灵顿）（P<0.001）。全膝关节置换术可获得满意的长期生存率。然而，随着时间的推移，生存率会下降。需要翻修 TKA 的风险与年龄和植入物类型有关。需要仔细考虑 TKA 的时间和植入物类型的选择。
