Clinical Specialty
Shoulder and Elbow Surgery

Clinical Interests
Dr. Yamaguchi's practice is limited to the treatment of shoulder and elbow disorders in adults. Particular interests include the minimally invasive treatment of rotator cuff disorders and shoulder instability with arthroscopic surgery. Additionally, he has one of the largest shoulder and elbow arthritis practices in the country, doing a significant amount of total shoulder and total elbow replacements.

Research Interests
His research program is focused on the natural history of rotator cuff disorders, clinical outcome of rotator cuff treatment, and the development of arthroscopic procedures.  He is the recipient, as PI, of an OREF CDA and NIH R01 x3 grant funding in this area.

Dr. Yamaguchi completed his residency training at George Washington University. He then completed fellowship training in shoulder surgery at the internationally recognized Shoulder Service at Columbian Presbyterian Medical Center in New York. This was followed by supplemental training in elbow surgery at the Mayo Clinic. In 1995, Dr. Yamaguchi founded the Shoulder and Elbow Service at Washington University, which has since become nationally and internationally recognized for innovations in shoulder and elbow surgery, as well as research on shoulder and elbow disorders. In 2006, the Service opened the Washington University Shoulder and Elbow Center, the first of its kind dedicated to the treatment of shoulder and elbow disorders. In December 2012, Dr. Yamaguchi received his MBA from the Olin Business School at Washington University in St. Louis.
