Robotic Surgery- The NAVIO Surgical System

The NAVIO system is an advancement in the way orthopedic surgeons perform partial knee replacement. The system works in conjunction with our surgeon’s skilled hands to achieve the precise positioning of the knee implant based on each patient’s unique anatomy. This added level of accuracy can help improve the function, feel and potential longevity of the partial knee implant. Through an advanced computer program, the NAVIO system provides robotic assistance that relays precise information about your knee to a robotics-assisted handpiece used by our surgeons during the procedure. By collecting patient-specific data, boundaries are established for the handpiece so we can remove the damaged surfaces of your knee, balance your joint, and position the implant with greater precision.
