The rising number of total knee arthroplasty (TKA) replacements and their uncertain functional results according to the revision etiology and the prosthesis model implanted are a challenge for orthopedic surgeons and patients. A better knowledge of these results is mandatory to make the best decision. We present our clinical outcomes with a 5-year follow-up.
We retrospectively reviewed 104 patients, 108 knees (77 aseptic and 31 septic), who underwent TKA revision surgery from 2007 to 2017 with three different models of prosthesis. KSS score, range of motion (ROM), pain, and independence for walking were recorded at 5 years according to our own database and the clinical interview and compared to the different models of prosthesis and the etiology of the revision.
The results showed 81.5 % of good or excellent functional outcomes in our patients with a mean KSS score of 76,7 ± 14,3, a mean ROM of 1.68 ± 0.30 radians, and 77 % of them are independent for walking without any aids. The results do not show any difference between the groups comparing the model of prosthesis and the etiology of the revision surgery.
At 5 years, TKA revision surgery offers good clinical and functional outcomes, independence for walking, good range of motion, and low residual pain regardless of the cause of the revision or the model of prosthesis.
全膝关节置换术（TKA）置换数量不断增加，且根据翻修病因和植入的假体型号，其功能结果存在不确定性，这对骨科医生和患者来说都是一项挑战。更好地了解这些结果对于做出最佳决策至关重要。我们展示了我们5年随访的临床结果。
我们回顾性分析了2007年至2017年期间接受TKA翻修手术的104例患者、108个膝关节（77例无菌性和31例感染性），这些患者使用了三种不同型号的假体。根据我们自己的数据库和临床访谈，在5年时记录膝关节协会（KSS）评分、活动范围（ROM）、疼痛程度和行走独立性，并与不同型号的假体以及翻修病因进行比较。
结果显示，我们的患者中有81.5%的功能结果为良好或优秀，平均KSS评分为76.7±14.3，平均ROM为1.68±0.30弧度，其中77%的患者无需任何辅助即可独立行走。在比较假体型号和翻修手术病因的组间，结果未显示出任何差异。
5年时，TKA翻修手术无论翻修原因或假体型号如何，都能提供良好的临床和功能结果、行走独立性、良好的活动范围以及较低的残余疼痛。
