The method as set forth in claim 1 including: displacing a patella from a normal position to an offset position with an articulating surface of the patella facing the femur; andcutting an articulating surface of the femur while maintaining the patella in the offset position with the articulating surface of the patella facing the femur. 10. The method as set forth in claim 1 including obtaining images of the knee joint and transmitting the images to a control unit. 11. The method as set forth in claim 10 wherein obtaining the images of the knee joint includes generating images of the knee joint during movement of a lower portion of a leg relative to an upper portion of the leg. 12. The method as set forth in claim 1 including viewing a first image of a distal end portion of the femur on a display during the surgery and viewing a second image of a proximal end portion of the tibia on the display during the surgery. 13. The method as set forth in claim 12 wherein viewing the images includes viewing relative movement between the distal end portion of the femur and the proximal end portion of the tibia. 14. The method as set forth in claim 1 including moving the tibia relative to the femur to display relative movement between a distal end portion of the femur and a proximal end portion of the tibia on a display before cutting away material from the femur and tibia. 15. The method as set forth in claim 1 including moving the tibia relative to the femur to display relative movement of a distal end portion of the femur and a proximal end portion of the tibia on a display after cutting away material from the femur and tibia. 16. The method as set forth in claim 1 including viewing a relationship between the femoral implant and the tibial implant on a display to evaluate the relationship between the femoral implant and the tibial implant. 17. The method as set forth in claim 16 including moving the tibia relative to the femur to display relative movement between the femoral implant and the tibial implant on the display after installing the femoral implant on the femur and installing the tibial implant on the tibia. 18. The method as set forth in claim 1 wherein cutting away material from the femur and tibia includes cutting away material from the femur and tibia while preserving at least a portion of a ligament of the knee joint. 19. The method as set forth in claim 1 wherein arranging the navigation system to track movement of the femur and tibia during the surgery includes: attaching a first plurality of reflectors to the femur; andattaching a second plurality of reflectors to the tibia,wherein the navigation system is an optical navigation system. 20. The method as set forth in claim 1 including viewing desired femoral cuts to be made to a distal end portion of the femur in order to receive the femoral implant. 21. The method as set forth in claim 20 including monitoring removal of material from the femur with respect to the desired femoral cuts. 22. The method as set forth in claim 21 including selecting a different size of the femoral implant during the surgery, wherein the desired femoral cuts are adjusted based on the different size. 23. The method as set forth in claim 21 including detecting a discrepancy between the desired femoral cuts and actual cuts made to the femur with the cutting tool of the robotic system. 24.
