Brian Feeley, MD

Orthopedic surgeon

Dr. Brian Feeley is an orthopedic surgeon who specializes in athletic injuries of the shoulder and knee and in treating them with arthroscopic procedures, which are minimally invasive. In the shoulder, he treats rotator cuff tears or impingement, labral tears and other causes of instability, clavicle fractures and shoulder arthritis and performs shoulder replacement. In the knee, he treats anterior cruciate ligament (ACL) and other ligament injuries, meniscus tears, cartilage injuries and early arthritis.

Feeley's research focuses on common knee and shoulder problems, including causes of muscle atrophy after rotator cuff tears. He also investigates how stem cells within muscle change the muscle tissue and how to stimulate these cells to improve function. In the knee, he researches how to use low-cost motion analysis to decrease injury or re-injury after initial damage and surgical procedures.

After earning his medical degree at Stanford University School of Medicine, Feeley completed a residency in orthopedic surgery at UCLA Medical Center. He then completed a fellowship in sports medicine and shoulder surgery at the Hospital for Special Surgery, where he served as an assistant team physician to the New York Giants football team.

Feeley has published more than 120 peer-reviewed articles, review studies and book chapters, as well as a book on rotator cuff injuries. He has received Young Investigator awards from the American Orthopaedic Society for Sports Medicine, Orthopaedic Research and Education Foundation and Western Orthopaedic Association. He is an associate professor in residence at UCSF.

Feeley serves as physician for St. Ignatius College Preparatory's athletic teams. He is the sports medicine fellowship director and associate program director for orthopedic surgery residency at UCSF. In his spare time, he likes to surf in Northern California and coaches his two daughters' softball teams in San Francisco Little League.
