Computer Assisted Total knee Replacement helps replacing knee joint with aid of a computer guided system. Many studies have shown that well aligned and balanced knee replacements are likely to last longer and feel better. While experienced surgeons get near-accurate alignment most of the times, but Computer Assisted surgery enhances surgical outcome by helping surgeon align the patient’s bones and implants with a degree of accuracy not possible with the naked eye.

Just like navigation system in new age cars provide driving directions using satellite navigation system with precision, speed and accuracy not attainable with a map and compass, computer assisted joint replacement offers visual mapping of patient’s anatomy or bone structure that helps the operating surgeon make crucial decisions before and throughout the procedure. It combines the precision and accuracy of computer technology with the surgeon’s skill to give best possible outcomes.


An anchoring pin is mounted into the bone. A navigation tracker is then mounted to the anchoring pin. This tracker continuously interacts with the Navigation system. Using imagery from the infrared cameras, the computer creates a highly detailed 3D model of the knee. After studying the model, plan for repairing the joint is created. The computer helps determine the precise angle of cuts that need to be made, the size and shape of the implants needed, and the proper alignment of the implants. The system also gives the surgeon real time feedback during the surgery and reduces chances of error by alerting the surgeon to potential pitfalls before they are performed.

Benefits of Computer Assisted Knee Replacement

Besides allowing maximum possible accuracy, Computer Assisted Knee Replacement enables surgery through a smaller incision. It also reduces few but significant surgical steps causing reduced trauma to the patient. Eventually blood loss the minimized and recovery is faster.

The system enables surgeon to view multiple views of the diseased knee simultaneously and take most accurate decision which is not possible otherwise.

There is reduced risk of X-Ray exposure to patient as well as OT staff.
