摘要
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.
