A prosthesis for the knee articulation is provided which has a femoral implant having two condyles which are of convex shape, each having a variable radius, and a tibial implant having two cavities, each of which interacts with a respective one of the condyles. In its posterior region, the internal condyle has a spherical prominence which projects from the contact plane of the internal condyle and is intended to interact with a spherical cap hollowed into the posterior region of the internal cavity of the tibial implant.
