The MIFAS by Grecmip brings together surgeons from all backgrounds and a passion for foot & ankle surgery and its percutaneous or arthroscopic improvement. We are an international group with various origins - hospitals, universities or private centres - who wants to promote this minimally invasive surgery. Therefore we organize courses and congresses. For a technique to be recognized, it must be understood that it is effective but also reproducible. The MIFAS by Grecmip part is thus to assess and promote.
