Abstract:: Abstract: 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.
