      Collapse Overview
      Dr. C. Benjamin Ma is the chief of the UCSF Sports Medicine and Shoulder Service. His special interests include sports medicine, arthroscopic shoulder surgery to repair rotator cuff tears and ligament instability, shoulder replacement, knee ligament reconstruction, meniscus and cartilage injury, and elbow arthroscopy. He has received many clinical and research awards which include the UCSF Exceptional Physician Award, Henry Kaiser Award for Excellent in Teaching and UCSF Excellent in Teaching Award.
      In addition to his clinical specialties, Dr. Ma is involved in research on cartilage imaging and dynamic magnetic resonance imaging (MRI) scans of ACL injured knees. He has also extensive publications on the improvement of outcomes following rotator cuff surgeries and replacements. His research has received the prestigious Charles Neer Award from American Shoulder and Elbow Society, Excellence in Patellofemoral Research from the International Society for Arthroscopy, Knee Surgery and Orthopaedic Sports Medicine and New Investigator Research Award from the Orthopaedic Research Society.
      Dr. Ma completed his undergraduate education in bioelectrical engineering at Brown University and went on to earn his medical degree from Johns Hopkins University. He completed his residency in orthopedic surgery at the University of Pittsburgh, where he also completed a one-year musculoskeletal research fellowship. Following his residency, Ma completed a second fellowship in shoulder and knee surgery and sports medicine at the Hospital for Special Surgery in New York
