for foreign patients and doctors
We are welcome overseas patients who want to undergo knee reconstructive surgery (total and uni compartmental knee arthroplasty) and regeneration therapy using fat-tissue stem cells.
We also provide fellowship program for overseas doctors regarding knee surgery (arthroplasty and arthroscopy) and regenerative therapy. After the fellowship, the doctor can get certificates from the government
Ministry of Health, Labor and Welfare) and from our institution. Our program can help you to improve your knowledge, skill and carrier.
