运动力学对线在初次全膝关节置换术中的应用研究进展

Development of kinematical alignment in primary total knee arthroplasty

全膝关节置换术(total knee arthroplasty,TKA)的临床效果很大程度上与术后下肢力线的优良率有关。目前,临床上有多种TKA术中下肢对线的方法,其中经典的机械力学对线(mechanical alignment,MA)仍然是目前全世界范围内TKA下肢对线的主要方式。然而越来越多的研究开始关注MA并非能完全恢复正常人下肢的对线。运动力学对线(kinematical alignment,KA)是近年来新提出的一种TKA对线技术,已有相关文献报道其不同于MA的术后下肢力学表现。本文就KA的相关研究,做一研究进展综述。

The clinical effect of total knee arthroplasty（TKA） is largely related to postoperative lower limb alignment. At present, there are many methods for correcting lower limb alignment during TKA, among which the mechanical alignment（MA） is still the most popular way worldwide. However, more and more studies have focused on the fact that MA does not completely restore the normal lower limb alignment. Kinematical alignment（KA） is a newly developed TKA alignment technique in recent years, and different results were reported in several studies. In this paper, the related researches of KA are reviewed.
