Optimal control of cutting feed rate in the robotic milling for total knee arthroplasty

For the total knee arthroplasty, we developed the robotic system, such as the cutting feed rate is controlled depending on the hardness of the bone tissue predicted on the basis of the medical image. Since the cutting force is reduced by this system, the displacement of the bone is minimized during the bone cutting process. Therefore it makes a possibility to fix the target bone using “safer” and less-invasive fixation technique.
