Abstract :
Surgical navigation system has been widely used by surgeons to improve alignment accuracy during Total Knee Arthroplasty (TKA). In this article, we present an image-free surgical navigation system for TKA with a more interactive and robust in-house developed Graphical User Interface (GUI). The navigation system has a more intuitive view and can trace surgical steps easily by saving surgery information data. System steps, feature of the interactive GUI, coordinate definition and osteotomy value/angle calculation method have been introduced. The stability and accuracy test are performed.
