The traditional approach of restoring a neutral mechanical axis to the lower extremity during total knee arthroplasty (TKA) and unicompartmental knee arthroplasty (UKA) has long been favored due its consistency and reproducibility. The kinematic alignment approach, which accounts for the patient's natural knee alignment and is commonly a few degrees varus to the mechanical axis, has gained popularity in recent years as a technique which reestablishes a more anatomic alignment. Linked Anatomic Kinematic Arthroplasty (LAKA), an extension of the kinematic approach that employs computer-assisted surgical (CAS) navigation, can improve the accuracy and precision of kinematic measurements in unicompartmental knee arthroplasties. This article will describe the LAKA technique in UKA and review early clinical outcomes associated with this technique.
在全膝关节置换术（TKA）和单髁膝关节置换术（UKA）中，通过恢复下肢中立机械轴的传统方法长期以来因其一致性和可重复性而受到青睐。运动学对线方法考虑了患者自然的膝关节对线情况，通常相对于机械轴有几度内翻，近年来作为一种能重建更解剖学对线的技术而受到欢迎。联合解剖运动学置换术（LAKA）是运动学方法的延伸，采用计算机辅助手术（CAS）导航，可提高单髁膝关节置换术中运动学测量的准确性和精确性。本文将描述UKA中的LAKA技术，并回顾与该技术相关的早期临床结果。
