Thank you for coming into our site!

Our department has been established in 1974, therefore it has nearly 50-year history. Since May 2012, we have stated our new era with our leader, Professor and Chairman Masao Akagi, who is a world-famous knee surgeon for the “Akagi line” in Total Knee Arthroplasty. Our department consists of 5 clinical units for subspecialty, including “Joint surgery”, “Hand surgery”, “Trauma”, “Spine surgery”, and “Bone and soft-tissue tumor”. Professor Akagi, Professor Kakinoki, Associate Professor Ohtani, Associate Professor Miyamoto, and Lecturer for medicine Nishimura is working as a director of the unit, respectively.

Policy of our department includes the following three key words.

  1. Ambition
  2. Cooperation
  3. Equality

We call this idea “Spirits of ACE”.
Based on this policy for education, clinical practice and research, we are making our utmost effort every day to be orthopaedic surgeons with international activities and to become a world leading department.

Introduction of our treatment groups

Joint surgery

Unit of Joint surgery, Kindai University Hospital, is conducted by five faculty members: Masao Akagi, MD, PhD, Shinji Inoue, MD, Kohichi Nakagawa, MD, Ichiro Tsukamoto, MD, Kohtaro Yamagishi, MD. Clinical and research activities of this unit cover treatments for osteoarthritis/rheumatoid arthritis of the all major joints and sports medicine including arthroscopic knee and shoulder surgery.

This unit is very famous for total hip/knee arthroplasty and unicondylar knee arthroplasty and for high research activities on surgical techniques. A new topic of this unit is introduction of a smart surgical robot for knee replacement surgery to the University Hospital, which is the first in Japan (March, 2019). Name of the robot is “NAVIO” (Smith and Nephew) and the new era of knee joint replacement surgery in Japan is about to begin with this smart and multi-talent handheld-type robot from Kindai University Hospital, Osaka-Sayama.

Basic research interest is focused on relationship between osteoarthritis development and the lifestyle-related diseases (hypertension, atherosclerosis, hyperlipidemia, and so on). Now we are working on in-vivo study using Tsukuba hypertensive mouse (human renin and angiotensinogen transgenic mouse) to elucidate effects of local renin angiotensin system (RAS) activation on osteoarthritis development.

Hand Surgery

We are treating all diseases and traumatic injuries of the upper extremities including bone and ligament disorders, nerve palsy, vascular diseases, rheumatoid arthritis etc except shoulder joint diseases.

Therapeutic Features

  • Treatment of nonunions of the extremities (including scaphoid nonunions) using vascularizd bone graft. (Nonunions or tissue defects in the upper and lower extremity are repaired using microsurgical tissue transplantation technique.)
  • Treatment of brachial plexus injury (BPI) using free muscle transfer combined with neurotization. (We reconstruct the upper extremity function of patients with brachial plexus injury by transplantation of muscles harvested from the thigh.)
  • Treatment of Kienboeck’s disease using vascularizd bone graft
  • Arthroscopic assisted treatment of triangular fibrous cartilage complex (TFCC) injury
  • Treatment of peripheral nerve palsy using nerve and tendon transfer
  • Arthroscopic assisted carpal tunnel release (Carpal tunnel syndome (CTS) is treated using an arthroscopy with small skin incisions.)
  • Treatment of congenital hand anomaly
  • Treatment of hands with inflammatory disorders such as rheumatoid arthritis.

Spine Surgery

Spine division of Orthopaedic department from Kindai University Hospital provides appropriate treatment for patients who suffer a various types of spine problems due to spondylosis, disc herniation, OPLL, rheumatoid arthritis, spinal deformity, metastasis, tumor, infection, spinal stenosis, trauma, and osteoporosis at any spine regions.

Our therapeutic algorism includes conservative treatments (prescription of medication and injections) and surgery, and adequate choice should be done depending on the patient conditions.

We can provide technically demanding types of surgeries including spinal osteotomy, cervical kyphosis correction using pedicle screw, reconstruction surgery for spinal tumor, infectious spine, and osteoporotic vertebral fracture. Highly-complicated surgery will be carried out at hybrid operating room in which Artis Zeego has been launched, and we can provide safer and faster services.

Scientific activities such as presentation and paper publish from our spine team has been evaluated not only domestically but also worldwidely.

Musculoskeletal oncology

Bone and soft tissue tumor are rare and uncommon diseases in orthopaedic. We are musculoskeletal oncology specialists. Our team have approximately 150 surgical cases each year which include limb salvage surgery for malignant soft tissue and bone tumors and benign tumors. We also use aggressive adjuvant and neoadjuvant chemotherapies in adult patients. We aim to provide comprehensive medical care in collaboration with oncologists, radiotherapists and pathologists.

Subspecialty: Surgery of the bone and soft tissue tumor
Basic research for musculoskeletal Oncology


Center of Musculoskeletal trauma

This center was opened in April 2018. The medical staff of this center is consists of three orthopaedic surgeons specializing in traumatic injury. We respond to several musculoskeletal trauma including spinal injury, fracture ( closed and/or open), and soft tissue injury 24 hours a day, 365 days a year. Patients are transferred to the emergency room (ER) or critical care unit (CCU). As for severe limbs injury such as poly trauma, open injury, spinal injury and pelvic injury, we perform treatment in corporation with the medical staff of ER or CCU. As for falls and fractures in hospitalized patients, we perform treatment consistently from the onset. Surgical treatment undergoes anytime as soon as possible with orthopaedic surgeons specializing in spinal, hand and joint surgery.
