1. A system for performing surgery on a femur and tibia of a knee joint, said system comprising:
- a robotic subsystem including a cutting tool;
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;
a display in communication with said control unit; and
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.

Abstract
A system for performing surgery on a joint. The system includes a robotic subsystem and a navigation subsystem. The navigation subsystem provides the robotic subsystem, during the surgery, with information relating to positions of the bones associated with the joint thereby enabling separate tracking of the bones when the bones move during the surgery. The robotic subsystem includes a base, a plurality of arms, and a cutting tool. The navigation subsystem may include a plurality of locating devices.

29. A system for performing surgery on a femur and tibia of a knee joint, said system comprising:
-
a robotic subsystem including a cutting tool and controls to move the cutting tool; a navigation subsystem in communication with said robotic subsystem, said navigation subsystem including a plurality of locating devices; a display; and a control unit in communication with said display and said robotic subsystem to display a position of said cutting tool relative to the femur or tibia on said display during cutting of the femur or tibia, wherein said navigation subsystem is configured to provide said robotic subsystem 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 the position of said cutting tool relative to the femur and tibia so that said controls of said robotic subsystem are capable of guiding movement of said cutting tool relative to the femur and tibia to cut away material from the femur and tibia without the use of physical resection guides.

30. A system for performing surgery on a femur and tibia of a knee joint, said system comprising:
-
a robotic subsystem including a cutting tool and controls to move the cutting tool; a navigation subsystem in communication with said robotic subsystem and including a first plurality of reflective locating devices for attaching to the femur and a second plurality of reflective locating devices for attaching to the tibia, wherein said navigation subsystem is configured to provide said robotic subsystem 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 the 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 using non-physical cutting guides; a display; a control unit in communication with said display and said robotic subsystem to display a position of said cutting tool relative to the femur or tibia on said display during cutting of the femur or tibia; and a user interface to input data corresponding to desired sizes of implants for the femur and tibia so that predetermined non-physical cutting guides associated with the desired sizes of implants are used to guide movement of said cutting tool relative to the femur and tibia.
