An image-free surgical navigation system for Total Knee Arthroplasty

摘要

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.
