Abstract:
1. A method of preparing a femur and tibia in surgery on a knee joint using a navigation system and a robotic system including a cutting tool, said method comprising the steps of: arranging the navigation system to track movement of the femur and tibia during the surgery; cutting away material from the femur with the cutting tool of the robotic system and without the use of physical resection guides, wherein the navigation system cooperates with the robotic system to provide the robotic system with information as to a position of the femur and a position of the cutting tool relative to the femur to guide movement of the cutting tool; cutting away material from the tibia with the cutting tool of the robotic system and without the use of physical resection guides, wherein the navigation system cooperates with the robotic system to provide the robotic system with information as to a position of the tibia and a position of the cutting tool relative to the tibia to guide movement of the cutting tool; installing a femoral implant on the femur; and installing a tibial implant on the tibia, wherein the navigation system enables separate tracking of the femur and tibia so that the positions of the femur and tibia can be determined when the femur and tibia move during the surgery.
