At UCSF, the National Stem Cell Foundation is partnering with the Orthopaedic Research and Education Foundation to support the work of Dr. Brian Feeley. Rotator cuff (RC) tears are the most common shoulder injury, affecting up to 50% of the population over 65. After injury and repair, changes in the muscle can influence clinical outcomes.
Dr. Feeley is working with a newly discovered muscle stem cell population to investigate new treatment options and improve clinical outcomes for these debilitating injuries.
Dr. Feeley joined the UCSF Department of Orthopaedic Surgery in 2008, and is currently an Associate Professor in Residence. He received his Bachelor of Science degree from Stanford University and his Medical Degree from Stanford University School of Medicine before serving his residency in the UCLA Department of Orthopaedic Surgery. He completed a sports medicine and shoulder fellowship at the Hospital for Special Surgery in New York City, where he also served as an assistant team physician to the New York Giants.
Dr. Feeley’s clinical focus is on athletic injuries of the shoulder and knee and the use of minimally invasive/arthroscopic procedures to treat these problems. In the shoulder, he treats rotator cuff tears/impingement, shoulder instability and labral tears, clavicle fractures, shoulder arthritis and shoulder replacement with reverse shoulder arthroplasty. In the knee, he treats ACL and other ligament injuries, meniscus tears, cartilage injuries, and early arthritis.
In the shoulder, he is researching the molecular mechanisms that are responsible for the development of muscle atrophy after rotator cuff tears. He is evaluating how stem cells residing within the muscle result in changes to the muscle tissue, and how to stimulate these cells to differentiate in ways to improve muscle function.
In the knee, he is evaluating techniques to use low cost motion analysis to improve lower extremity kinematics and decrease injury and re-injury risk after injuries and surgical procedures.
He has published over 120 peer reviewed articles, review studies, and book chapters, as well as a book on rotator cuff injuries. He has received the AOSSM and OREF Young Investigator Awards for his research, and in 2012 received the Western Orthopaedic Young Investigator Award.
He is currently funded by the NIH and OREF for his research, and was the 2014 Kappa Delta Young Investigator Award winner from the OREF and ORS. In 2017, he won teaching awards from the UCSF school of medicine and a research award from the AOSSM.
Dr. Feeley is currently the team physician for St. Ignatius College Prep High School. He also serves as the UCSF sports medicine fellowship director and associate program director for the UCSF Orthopedic Surgery residency.
