An advantage is that the doctor has greater "vision" when it counts - during surgery. The computer system captures the patient’s unique anatomy and translates it to a computer screen, providing an unobstructed view of the patient's knee joint. This supports decision making and enhances the surgeon's flexibility

The cameras take data via infrared signals from reflectors placed on the patient's body and on specially designed surgical instruments. The computer uses the data to track the exact position of the patient and the instruments on a monitor. The combination of computer visualization and special surgical instruments allows doctors to align the implant with greater precision than when doing the procedure with the naked eye.
