Akihiko Hasegawa, MD, PhD

Dr. Akihiko Hasegawa is a respected orthopedic shoulder surgeon known for his contributions to biomechanical research, tendon healing science, and arthroscopic shoulder surgery. He has collaborated with leading Japanese research centers investigating the mechanics of the rotator cuff, superior capsule function, and graft-based reconstruction techniques.

His work supports the international progression of shoulder biomechanics, particularly in understanding how graft tension, capsule integrity, and deltoid function influence postoperative outcomes. Clinically, Dr. Hasegawa specializes in arthroscopic rotator cuff repair, instability surgery, tendon transfers, and biologic augmentation for complex shoulder conditions.
