Hideyuki Koga, MD, PhD (Orthopaedic Surgery and Sports Medicine)

Department of Joint Surgery and Sports medicine, Tokyo Medical and Dental University, Tokyo, Japan

Dr. Koga graduated from Tokyo Medical and Dental University (TMDU) in 1999, and joined Department of Orthopaedic Surgery, Tokyo Medical and Dental University. After clinical fellowship, he also entered graduate school and have defended PhD at TMDU in 2008 with the main topics regarding cartilage regeneration using mesenchymal stem cells. Then he went to Oslo Sports Trauma Research Center, Norway from 2008 until 2010. His research topic was regarding knee anterior cruciate ligament (ACL) injury prevention, and clarified detailed ACL injury mechanisms first in the world using a sophisticated 3D video analysis called model-based image-matching technique. He is still working on ACL injury prevention, especially focusing on ski injury as a member of medical committee, International Ski Federation, and recently also as a member of scientific committee, IOC World Conference Prevention of Injury and Illness in Sport.

Since 2010 after back to Japan, Dr. Koga has been doing many double-bundle ACL reconstructions, reconstructions of multiligament knee injuries, as well as meniscus surgeries at TMDU. He has done and is doing some clinical and biomechanical researches regarding knee ligament and meniscus surgeries, especially focusing on double-bundle ACL reconstruction. His another hot topic now is meniscus preservation. The meniscus plays important roles in protecting the articular cartilage through absorbing joint loading. Extrusion of the meniscus suggests failure of load absorbing function, and is correlated with progression of OA. However, there had been no effective surgical procedures for meniscus extrusion. He has developed a new surgical procedure called arthroscopic centralization to reduce/prevent meniscus extrusion. Currently He is applying this technique to OA knees to reconstruct knee function, hopefully to prevent progression of OA and consequently to reduce the number of patients with severe OA who require knee arthroplasty. Until now he has published more than 120 papers, has given lectures or had presentations at many international congresses.

Dr. Koga became the Director of the Department of Joint Surgery and Sports Medicine, TMDU in 2017. He honorably obtained the traveling fellowship between JOSKAS (Japanese Orthopaedic Society of Knee, Arthroscopy, and Sports Medicine) and SIGASCOT (Società Italiana del Ginocchio Artroscopia Sport Cartilagine Tecnologie Ortopediche) in 2016. He also serves on the editorial board of Journal of Orthopaedic Science and Asia-Pacific Journal of Sports Medicine, Arthroscopy, Rehabilitation and Technology.
