About Dr. Bargar

Dr. William Bargar is a hybrid.He has two degrees in engineering as well as his MD. These have been very helpful to him both in his research and his practice of Orthopaedic Surgery. He joined the faculty of UC Davis in 1981 after completing his residency at Case-Western and a fellowship at UCLA in Joint Replacement and Bioengineering. In 1986 Dr. Bargar began private practice in Sacramento at Sutter General Hospital, but he has continued his active research at the U.C. Davis Research Labs as well as the Sutter Institute for Medical Research. He is considered a leader and early developer of Computer-Aided Surgery (CAS) and is a frequent speaker at national and international meetings on the subject.

In the early 1980’s Dr. Bargar developed a new approach to cementless total hip replacement using custom-made prostheses with CT generated CAD/CAM techniques. This has brought him many patients with anatomic variations for which standard implants are not appropriate. He is also the co-developer of “ROBODOC”, a surgical robotic device for improving accuracy and precision in orthopaedic surgery that is used around the world. He is the recipient of the Engelberger Award for “Contributing to the Advancement of the Science of Robotics in the Service of Mankind” as well as the Smithsonian Award for the “Use of Computers in Medicine”. He has written numerous scientific articles and book chapters on total hip and knee surgery. Dr. Bargar has performed over 7,000 hip and knee replacements including many revision surgeries for failed hip and knee replacements.

Dr. Bargar retired from surgical practice at the end of 2014 and closed his private office, but he continues to see follow-up and new patient consultations in the offices of Orthopaedic Specialists of Sacramento.
