Orthopaedic surgery is the science that deals with diseases of the locomotor system and aims to elucidate the pathology of the locomotor system and develop new treatment methods. Locomotory organs refer to the spine, spinal cord, and all organs involved in the form and movement of individuals in the trunk and extremities, and is characterized by a wide variety of pathologies and a large number of diseases. Our Department has a long history, established in 1924, and recently welcomed Professor Ken Okazaki in April 2017 after Professor Tatsuo Ito from 1991 and Professor Yoshiharu Kato from 2007. We are dedicated to a wide range of orthopaedic surgery, including knee, spinal cord, hip, shoulder, hand and elbow, oncology, and foot surgery, as well as to research and education. Furthermore, in May 2019, we merged with the Department of Orthopaedic Surgery of our Collagen Disease and Rheumatology Gout Center and has become involved in many surgical cases of rheumatic diseases.
Our staff of each specialty group provide lectures. Students are assigned to each group for practical training on the hospital wards, where they attend morning conferences conducted every day, observe surgeries, make rounds of the wards, and write reports and presentations on the patients they are in charge.
As one of the elective courses, the residents work together with each group staff, including late residents, in medical practice activities. Clinical education is provided through orthopaedic care.
Under the training program of the Japanese Orthopaedic Association, the primary goal is to obtain a specialist in orthopaedic surgery, and advanced and sufficient training will be provided at the university hospital and affiliated facilities. For details, please refer to our Department's website.

We are conducting clinical research on a wide variety of spine cases, including dialysis spine cases, which is one of the largest numbers of cases in Japan; clinical research including patient-oriented outcomes for knee joint diseases using not only artificial joints but also osteotomies such as Around Knee Osteotomy (AKO), which has become a hot topic in recent years; and image analysis and biomechanical research using 3D software. We are also conducting research on image analysis and biomechanics using 3D software. In addition, we conduct clinical research using the IORRA cohort, which has one of the highest numbers of rheumatology cases in the country.
In addition, we are conducting research on new materials for anterior cruciate ligament reconstruction using large animals at the Tokyo Women's Medical University-Waseda University Joint Institution for Advanced Biomedical Sciences (TWIns).
We also encourage students to study abroad, both in Japan and overseas, and one young student is currently engaged in research on cartilage regeneration at Harvard University in Boston.
