Patrick E. Greis, MD

Dr. Patrick Greis, Board Certified Professor of Orthopaedic Surgery, joined the Department of Orthopaedics in March of 1997 and specializes in sports medicine, knee and shoulder surgery. His interests include all aspects of knee and shoulder surgery, including arthroscopic surgery, ACL reconstruction, shoulder instability, rotator cuff issues, arthritis of the sholder, and the treatment of sports-related injuries.

Dr. Greis’ research interests include evaluation of rotator cuff function, rotator cuff reconstruction, and the evaluation of clinical results of ACL reconstruction. Trained at the University of Michigan in Ann Arbor, Dr. Greis completed a residency at the University of Pittsburgh, and a sports medicine fellowship at the Steadman-Hawkins Clinic in Vail, Colorado. Dr. Greis practices at the University of Utah Orthopaedic Center and is availible in clinic on Tuesday and Friday.
