The method as set forth in claim 1 including: forming a recess in one of the femur or tibia with the cutting tool of the robotic system and without the use of physical resection guides such that the recess is peripherally surrounded by naturally occurring bone; andpositioning a first implant member in the recess. 12. The method as set forth in claim 1 wherein cutting away material from the femur includes cutting away material from only one of a medial and lateral condyle without cutting away material from the other of the medial and lateral condyles. 13. The method as set forth in claim 1 including making a minimally invasive incision to access the knee joint wherein the minimally invasive incision has a length that does not exceed thirteen centimeters. 14. 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. 15. The method as set forth in claim 1 including obtaining images of the knee joint and transmitting the images to a control unit. 16. The method as set forth in claim 15 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. 17. The method as set forth in claim 15 including displaying the transmitted images on a display for viewing during the surgery. 18. The method as set forth in claim 17 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. 19. 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. 20. The method as set forth in claim 19 including moving the tibia relative to the femur to display relative movement of the distal end portion of the femur and the proximal end portion of the tibia on the display after cutting away material from the femur and tibia. 21. The method as set forth in claim 1 including displaying a relationship between a first implant member and a second implant member on a display to evaluate the relationship between the first implant member and the second implant member. 22. The method as set forth in claim 1 including: affixing a first implant member to the femur;affixing a second implant member to the tibia; andmoving the tibia relative to the femur to display relative movement between the first implant member and the second implant member on a display after affixing the first implant member to the femur and affixing the second implant member to the tibia. 23.
