The method as set forth in claim 5 wherein indicating the volumes of material to be removed from the femur and tibia includes indicating desired femoral cuts relative to a distal end portion of the femur based on a size of a femoral component of a knee implant and indicating desired tibial cuts relative to a proximal end portion of the tibia based on a size of a tibial component of the knee implant. 7. The method as set forth in claim 6 including adjusting the size of one of the femoral or tibial components during the surgery and adjusting the volume of material to be removed from one of the femur or tibia based on the adjusted size. 8. The method as set forth in claim 6 including detecting a discrepancy between the desired femoral or tibial cuts and actual cuts made with the cutting tool of the robotic system and activating one of an audible alert or a visual alert in response to detecting the discrepancy. 9. The method as set forth in claim 8 wherein activating one of the audible alert or visual alert includes activating the visual alert by changing displayed colors viewable by a user from green to red. 10. The method as set forth in claim 8 including interrupting operation of the robotic system upon detecting the discrepancy. 11. The method as set forth in claim 1 including displaying desired cuts to be made to the femur or tibia wherein the desired cuts correspond to a desired size of one of a femoral or tibial component of a knee implant. 12. The method as set forth in claim 11 including displaying the desired cuts with respect to a distal end portion of the femur or a proximal end portion of the tibia. 13. The method as set forth in claim 11 including generating an image of the desired cuts to be made to the femur or tibia. 14. The method as set forth in claim 13 wherein generating the image of desired cuts to be made to the femur or tibia includes generating a three-dimensional optical image. 15. The method as set forth in claim 1 including: transmitting images of the knee joint to a control unit; anddisplaying the transmitted images on a display for viewing during the surgery. 16. The method as set forth in claim 15 wherein displaying the transmitted images includes displaying relative movement between a distal end portion of the femur and a proximal end portion of the tibia. 17. The method as set forth in claim 1 including displaying relative movement of a distal end portion of the femur and a proximal end portion of the tibia on a display. 18. The method as set forth in claim 1 including: tracking movement of the femur with a first plurality of locating devices attached to the femur; andtracking movement of the tibia with a second plurality of the locating devices attached to the tibia. 19. The method as set forth in claim 1 including: tracking movement of the femur with a first plurality of emitters attached to the femur; andtracking movement of the tibia with a second plurality of emitters attached to the tibia. 20.
