Benjamin C. Ma, MD

Dr. Benjamin Ma is a renowned academic surgeon, educator, and clinical researcher specializing in rotator cuff repair, biologic augmentation, shoulder instability, and soft tissue healing. As Chair of Orthopaedic Surgery at UCSF, he brings extensive expertise in integrating translational research with evidence-based surgical decision-making.

His work focuses on improving healing rates after arthroscopic rotator cuff repair (ARCR), understanding tendon biology, evaluating the role of biologic agents in tissue regeneration, and refining reconstructive techniques for massive, irreparable tears. Dr. Ma has also contributed substantially to the study of postoperative outcomes, tendon healing predictors, and graft-augmented procedures, influencing global surgical practice.
