Edward M. Wojtys, M.D.

  • William S. Smith Collegiate Professor of Orthopaedic Surgery, Sports Medicine
Edward M. Wojtys, M.D., is the William S. Smith Collegiate Professor in the University of Michigan’s Department of Orthopaedic Surgery and chief of sports medicine at U-M’s MedSport Program. He is a former U-M football player who completed his medical training and orthopaedic residency at the University of Michigan and fellowship at Cincinnati Sports Medicine under the direction of Dr. Frank Noyes in Knee Surgery and Sports Medicine. He joined the U-M faculty in 1985; his clinical and research work focuses on the mechanisms of knee injuries and their treatment. He currently serves as co-chair of the NFL Orthopaedic Research Committee, and recently received the 2016 Kappa Delta Award from the American Academy of Orthopaedic Surgeons (AAOS) and Orthopaedic Research Society (ORS)—the highest research award given by these societies.  His research has been funded by the NIH, NFL, Coulter Foundation, and the Center for Organogenesis. Michigan Medicine is proud to recognize and support Dr. Wojtys’ many contributions to Orthopaedic Surgery and Sports Medicine.
