摘　　要：在全膝关节置换术(TKA)中,计算机辅助外科(CAS)导航旨在通过提高假体定位的精准性来提高下肢整体的对齐。目前主要有3种CAS导航系统:基于图像系统的大型控制台导航、无图像的大型控制台导航、以及最新开发的手持式导航系统。META分析显示,传统CAS导航技术对于控制TKA中的机械轴线对齐有重要作用。与传统技术相比,手持式CAS导航成本更低,且不会侵犯股骨/胫骨管及增加额外的操作区外的控制台,在未来有更加广阔的应用前景。同时有研究表明CAS导航提升机械对准对于TKA预后并无很明显的改善,这与传统观点并不符合,因此CAS技术对于关节置换的重要性还需进一步的研究佐证。The computer-assisted surgical (CAS) navigation in total knee arthroplasty (TKA) aims to improve the overall alignment of the lower limbs by increasing the accuracy of prosthesis positioning. Nowadays, there are 3 types of CAS navigation systems, namely large console navigation based on image systems, large console navigation without images, and the newly developed handheld navigation system. META analysis shows that traditional CAS navigation system plays an important role in controlling the mechanical axis alignment in TKA. Compared with traditional technologies, handheld CAS navigation has a broader application prospect in the future for it costs less, without invading the femur/tibia tube or adding extra consoles outside the operating area. However, some studies reveal that using CAS navigation to improve mechanical alignment does little to improve the prognosis of TKA, which is not consistent with the traditional view. Therefore, further research is needed to confirm the importance of CAS navigation system for joint replacement.
