The purpose of the present study was to analyze the survival rate of implants and mode of failure after revision total knee arthroplasty (TKA) using one type of modular prosthesis by a single surgeon. From September 1990 to June 2009, 224 revision TKAs were performed in 194 patients. The 5-, 8-, and 10-year survival rates were 97.2%, 91.6%, and 86.1%, respectively. Re-revision TKAs were performed in 20 knees because of infection (seven knees), loosening (six knees), polyethylene wear (six knees), and periprosthetic fractures (one knee). The long-term survival rate of revision TKA was satisfactory, but careful attention is necessary to detect the late failure. The prevention of infection and the stable fixation of components are required at the time of revision TKA.
本研究旨在分析单名外科医生使用同种模块化假体进行翻修全膝关节置换术（TKA）后的植体存活率和失败模式。1990 年 9 月至 2009 年 6 月，194 名患者共进行了 224 例翻修 TKA。5 年、8 年和 10 年的存活率分别为 97.2%、91.6%和 86.1%。20 例膝关节因感染（7 例）、松动（6 例）、聚乙烯磨损（6 例）和假体周围骨折（1 例）而进行了再次翻修 TKA。翻修 TKA 的长期存活率令人满意，但需要仔细注意检测晚期失败。在进行翻修 TKA 时，需要预防感染和确保组件的稳定固定。
