Naoya Hirosawa, MD, PhD

Dr. Naoya Hirosawa is an established Japanese shoulder surgeon and researcher who has contributed extensively to tendon biology, fatty degeneration pathways, and biologic augmentation strategies in rotator cuff repair. His work also includes superior capsule biomechanics and surgical reconstruction techniques for massive cuff tears.

Clinically, he focuses on arthroscopic cuff repair, complex instability, and biologic graft reinforcement. His translational research bridges microarchitectural tendon science with real-world surgical application.
