Abstract:
1. A system for performing surgery on a femur and tibia of a knee joint, said system comprising: a robotic subsystem including a base, a support having an upper end portion rotatable relative to said base, a main arm pivotally attached to said upper end portion of said support and having an outer end portion, a secondary arm pivotally mounted to said outer end portion of said main arm and defining a longitudinal axis, a mounting section rotatable about said longitudinal axis and including a mount rotatable about a mounting axis, motors and controls supported by said base, and a cutting tool mounted to said mounting section; a navigation subsystem in communication with said robotic subsystem, said navigation subsystem including a plurality of locating devices; a control unit in communication with said robotic subsystem; and a display in communication with said control unit; wherein said navigation subsystem is configured to provide said robotic subsystem, during the surgery, with information relating to positions of the femur and tibia thereby enabling separate tracking of the femur and tibia when the femur and tibia move during the surgery and said navigation subsystem is configured to cooperate with said robotic subsystem to determine a position of said cutting tool relative to the femur and tibia to guide movement of said cutting tool relative to the femur and tibia to cut away material from the femur and tibia, wherein said control unit is configured to receive information relating to the position of said cutting tool relative to the femur and tibia such that movement of said cutting tool relative to the femur during the surgery is viewable on said display and movement of said cutting tool relative to the tibia during the surgery is viewable on said display.
