Ken Urish, MD, PhD, is a knee and hip replacement orthopedic surgeon. He completed his fellowship at the Massachusetts General Hospital and was an instructor with the Harvard Medical School. His practice focuses on primary and revision hip and knee arthroplasty (joint replacement). He is an innovator with extensive experience in robotic surgery, minimally invasive techniques, and addressing issues with failed or painful hip and knee replacements. He is Director of the Arthritis and Arthroplasty Design Group, a laboratory funded by the NIH to improve arthroplasty outcomes. He obtained his PhD in Bioengineering and was a visiting scientist with the Carnegie Mellon Robotics Institute.



Using traditional surgical methods, cutting blocks or guides are placed on the thigh bone (femur) and shin bone (tibia) to help direct a surgical saw in removing the diseased bone and cartilage. This method has been considered technically challenging, as accurately placing these blocks can be difficult. In recent years, advanced surgical techniques using robotic assistance have been developed to provide a higher level of accuracy and precision.

The NAVIO system is an advancement in the way our 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.
