The system also registers the three dimensional position and orientation of the patient's tibia and/or femur during the course of the knee replacement operation. The system is capable of applying tension to the ligaments of the patient's knee in flexion or in extension after resection of the patient's tibia. Moreover the computer is programmed to display images of the bones on the computer's screen at different stages of the operation and with potential planes of cut. | |
