膝关节表面置换术中运动力学对线的应用与发展

Application and development of kinematical alighment during total knee arthroplasty

全膝关节置换术中运动力学对线是一种新兴的截骨对线方式,正被越来越多的学者关注。通过运动力学对线,TKA术后膝关节更接近正常膝关节,从而具有较好的临床效果和功能评分,不会增加假体早期失败的概率。但可能会增加髌骨-股骨关节应力,导致髌骨轨迹不良,增加磨损。本文总结了全膝关节表面置换术中运动力学对线定义、基本原理、适应证及禁忌证、手术方法、临床效果及不足,指导TKA术中截骨对线方案的选择。

Kinematical alignment during total knee arthroplasty is an emerging process,and draws more and more attentions from scholars. Knee joint is close to nornal joint after TKA through kinematical alighment,which has good clinical results and functional scores,and not increase failure probility. Thus,it may increase joint stress of patella femur joint,lead to patellar maltracking and increase abrasion. The paper summarized defination and basical principle,operative method,clinical outcomes and deficiency of kinematical alignment during total knee arthroplasty,in order to choose a better way for kinematical alignment during total knee arthroplasty.
