F.I.R.S.T Prosthesis design
F.I.R.S.T Evolution


At the beginning of 2000, Professor Pierre-François Leyvraz, Department Head at the main Orthopaedic Hospital serving French-speaking Switzerland (Hôpital Orthopédique de la Suisse Romande) and Vincent Leclercq, a graduate engineer of the Federal Polytechnic School of Lausanne (EPFL), conducted an in-depth study, both theoretical and clinical, on total knee prostheses currently available on the market.

On the basis of the work undertaken over 15 years at the EPFL, the study led them to develop a new prosthesis with an improved articular design, which makes it possible to reduce the wear of the polyethylene, increase the stability of the implants and increase the amplitude of articular flexion.

A group of European surgeons has also contributed to the development of an optimal operative technique.
