Navigation System Provides Better Functional Outcomes of Total Knee Arthroplasty

Computer assisted navigation systems are currently being widely used in orthopedic surgery, and especially for total knee arthroplasty (TKA). Using a navigation system in knee surgery provided useful intraoperative information about the anatomical placement that’s done intraoperatively in real time. It helps perform accurate surgery, it improves the radiologically assessed implantation and it allows precise correction of a mechanical axis, and so we can expect improved clinical results. In this article, we review the navigation system, surgical method, advantages, disadvantages and presents a balanced view of navigationassisted TKA and discusses controversies about navigation systems regarding coronal alignment, axial alignment, and clinical outcomes.
