Benjamin Ma, MD, a highly regarded orthopedic surgeon and advanced imaging researcher, has been appointed as chair of the UCSF Department of Orthopaedic Surgery. Ma will assume his new role on January 1, 2024.
Ma specializes in diagnosing and caring for patients with sports medicine injuries, including arthroscopic shoulder surgeries to repair rotator cuff tears and ligament instability, shoulder replacements, knee ligament reconstruction, and procedures to address meniscus and other cartilage injuries. His research focuses on improving the outcomes following soft tissue musculoskeletal injuries.
In 2018, Ma assumed the position of vice chair of adult clinical operations at the UCSF Department of Orthopaedic Surgery. In 2020, Ma was appointed as the surgical director at the UCSF Mount Zion campus. From 2007 through 2019, he served as the chief of the division of Sports Medicine and Shoulder Surgery at UCSF, growing the faculty fourfold and earning recognition in clinical practice, locally and internationally. Ma has been a professor in the department of Orthopaedic Surgery since 2003.
Ma is involved in research on cartilage imaging and dynamic MRI scans of knees with injuries to the anterior cruciate ligament (ACL). His work has focused on early detection of cartilage injuries following ACL reconstruction surgery and improving ACL reconstruction outcomes. He is one of the founding members of the Multicenter Orthopaedic Outcome Network (MOON) shoulder group. He has published extensively on the improvement of outcomes following rotator cuff surgeries and replacements.
I have no doubt that Dr. Ma's history of exceptional clinical care and research, devotion to mentoring and supporting future leaders in musculoskeletal care, and commitment to diversity and equity in the field, position him well to lead the UCSF Department of Orthopaedic Surgery as they work to pioneer musculoskeletal discovery and innovative care to transform lives."
