Operating Mode and Surgical Procedure

For measuring the anatomical starting situation a transmitter is attached to the femur and a further one is attached to the tibia.

Further transmitters are attached to the instruments. This transmitters enable the recording of the instruments in respect to the patient anatomy during the surgery. This is important to get exact OR results. The camera is thereby tracking the position of the transmitter fixed to the bone.

By palpating the center of the artificial joint with an instrument the surgeon records knee joint, hip joint and ankle joint, which are needed for further navigation steps.

After a skin incision the musculature and the patella is pushed to the side and the knee joint is uncovered.

The used joint surfaces of femur and tibia are removed and the new surfaces for recording the new prosthesis are prepared to fit accurately. OrthoPilot® shows the exact position of the sawing gauge on the screen.

After executing the cuts the examination of the cutting result follows. The tension of the soft tissue, as well as the joint capsule and the ligaments can be take into consideration, through the information on the OrthoPilot® screen.

If it has come to a shortening of the ligaments, this can be determined and corrected with the help of the OrthoPilot® navigation system, in order to achieve a high stability of the knee joint.

As soon as an ideal implant bed has been created, the knee prostheses can be implanted. Thereby the OrthoPilot® is showing the adjustment and position of the implant components. 

In the final step the implant position is again checked with the OrthoPilot® and the data is stored.
