The purpose of this study was to investigate the use for screws and cement, and primary and revision specific prosthesis for revision TKA. Between July 1989 and February 2010, 839 consecutive revision TKAs were performed, with 609 knees meeting inclusion criteria. At 17 years followup, Kaplan-Meier survivorship was 0.9859 for revision specific prosthesis with screws and cement, 0.9848 for revision prosthesis with no screws, 0.9118 for primary prosthesis with screws, and 0.9424 for primary prosthesis with no screws. Revision TKAs using screws had greater defects (P<.0001). Use of revision prosthesis along with screws and cement to correct largely defective revision TKAs is highly recommended.
本研究的目的是调查用于翻修全膝关节置换术（TKA）的螺钉和骨水泥的使用情况，以及初次和翻修专用假体。在1989年7月至2010年2月期间，连续进行了839例翻修TKA，其中609例膝关节符合纳入标准。在17年的随访中，使用螺钉和骨水泥的翻修专用假体的Kaplan-Meier生存率为0.9859，不使用螺钉的翻修假体为0.9848，使用螺钉的初次假体为0.9118，不使用螺钉的初次假体为0.9424。使用螺钉的翻修TKA有更大的缺损（P<0.0001）。强烈建议使用翻修假体并结合螺钉和骨水泥来矫正严重缺损的翻修TKA。
