A Surgery Planning System by Visualizing 3D Profile of the Knee during Motion for Anterior Cruciate Ligament Reconstruction

摘要

Anterior cruciate ligament (ACL) reconstruction is one of the surgeries to recover the knee function. The ACL reconstruction attach the grafts which is harvested from other parts to the femur and tibia. The grafts connects the femur and tibia by passing through the bone tunnels. One of the techniques makes the bone tunnel of the femur and tibia in one line at a proper knee flexion angle. If the angle is improper, the bone tunnel is made at high risk of infection. So, it is important to visualize the virtual bone tunnels at various knee angle as a planning system. This paper proposes a new method to visualize 3D profile of the knee and the virtual bone tunnels during motion with 3D scanner and 3D electromagnetic sensors.
