Systems for total knee arthroplasties ("TKA") are described herein. Anatomical structures may be registered in position, sensed, and tracked in three dimensions according to the system of the invention, allowing surgeons to perform surgeries more effectively. The systems comprise an imager for providing images of portions of the knee joint, a position sensor, a computer to store images of knee joint portions, and receive position information, a TKA surgical instrument attachable to bone in the knee joint, and a monitor to display positioning information. |
