运动学对线应用于全膝关节置换术的研究进展

全膝关节置换术是目前治疗终末期膝关节骨性关节炎最有效的方法之一，全膝关节置换术后膝关节功能、术后膝关节疼痛与术后下肢力线有着密切的关系。目前膝关节置换术下肢对线方式主要采用机械力学对线方法，该方法可以改善膝关节功能，但是有部分患者也会产生术后膝关节的疼痛、活动受限等并发症，导致术后患者满意度较差。近些年越来越多的研究开始关注运动力学对线技术并应用于临床。运动学对线技术旨在重建患者的解剖结构，将膝关节假体运动轴与膝关节生理性运动轴保持一致，减少膝关节周围软组织和韧带的松解，实现膝关节生理性运动。该文就运动力学对线方法在全膝关节置换术中的应用进展作一综述。

Progress in the application of kinematic alignment in total knee arthroplasty

Total knee replacement is one of the most effective methods for the treatment of end-stage knee osteoarthritis. At present, the method of mechanical alignment is mainly used in the lower limb alignment of the knee replacement, which can improve the function of the knee joint, but some patients can also produce the postoperative knee joint pain, limited activity and other complications, resulting in poor satisfaction after operation. In recent years, more and more studies have begun to focus on moving mechanics alignment techniques and applied it to clinical practice. The kinematic alignment technique is aimed at the reconstruction of the anatomical structure of patients, keeping the motion axis of the knee joint prosthesis in line with the physiological motion axis of the knee joint, reducing the release of soft tissues and ligaments around the knee joint, and realizing the physiological kinematics of the knee joint. In this paper, the study of the method of dynamic mechanical alignment in total knee arthroplasty is reviewed.
