Abstract
A method for robotic surgery on a joint using a robotic system and a navigation system. The robotic system includes a base, a plurality of arms, and a cutting tool. The navigation system tracks movement of bones associated with the joint during the surgery. Information related to tracked positions of the bones is communicated from the navigation system to the robotic system. The navigation system may include a plurality of locating devices.

A method for robotic knee surgery on a femur and tibia of a knee joint, said method comprising the steps of:
- providing a robotic system including a cutting tool;
- providing a navigation system;
- tracking positions of the femur and tibia during the surgery with the navigation system as the femur and tibia move during the surgery;
- communicating information related to the tracked positions of the femur and tibia from the navigation system to the robotic system;
- guiding movement of the cutting tool of the robotic system relative to the femur and tibia so that material from the femur and tibia can be removed by the cutting tool without the use of physical resection guides;
- and
- removing material from the femur and tibia with the cutting tool and without the use of physical resection guides.
A method for robotic knee surgery on a femur and tibia of a knee joint, said method comprising the steps of:
- providing a robotic system including a cutting tool;
- providing a navigation system comprising a plurality of locating devices;
- tracking a position of the cutting tool during the surgery as the cutting tool moves relative to the femur and tibia during the surgery;
- tracking positions of the femur and tibia during the surgery as the femur and tibia move during the surgery;
- communicating information related to the tracked positions of the femur and tibia from the navigation system to the robotic system;
- controlling movement of the cutting tool of the robotic system relative to the femur and tibia based on the information related to the tracked positions of the femur and tibia being communicated to the robotic system from the navigation system so that material from the femur and tibia can be removed without the use of physical resection guides;
- and
- removing material from the femur and tibia with the cutting tool and without the use of physical resection guides.
A method for robotic knee surgery on a femur and tibia of a knee joint, said method comprising the steps of:
- providing a robotic system including a cutting tool and controls to move the cutting tool;
- providing a navigation system comprising a first plurality of locating devices for attaching to the femur and a second plurality of locating devices for attaching to the tibia;
- tracking positions of the femur and tibia during the surgery with the navigation system as the femur and tibia move during the surgery;
- communicating information related to the tracked positions of the femur and tibia from the navigation system to the robotic system;
- controlling movement of the cutting tool of the robotic system with the controls based on the information related to the tracked positions of the femur and tibia being communicated to the robotic system from the navigation system so that material from the femur and tibia can be removed without the use of physical resection guides;
- removing material from the femur and tibia with the cutting tool and without the use of physical resection guides;
- and
- providing non-physical cutting guides defining target shapes for the femur and tibia corresponding to desired femoral and tibial components to guide the removal of material from the femur and tibia.
