W. Dilworth Cannon, M.D.

Orthopedic surgeon

A nationally renowned sports medicine expert, Dr. W. Dilworth Cannon is part of the UCSF Sports Medicine Center. He has been involved in numerous committees of the American Academy of Orthopedic Surgeons and has been past president of the Arthroscopy Association of North America. Currently, he is chair of a committee to design an arthroscopic virtual reality knee simulator that should result in more efficient training of doctors and reduce surgical errors. Cannon also is interested in the treatment of articular cartilage injury and disease, and has a special interest in anterior cruciate ligament (ACL) revision surgery.

Cannon received his undergraduate degree from Yale University and his medical training from Columbia College of Physicians and Surgeons in New York. He completed an internship and surgical residency at St. Vincent's Hospital in New York before serving as a research associate at the National Institutes of Health (NIH). He then completed his orthopedic residency at New York Orthopedic Hospital before joining UCSF in 1972. Cannon is an active member of many organizations, and is co-editor of the journal Sports Medicine and Arthroscopy Review.
