Abstract

The invention concerns a tibiotalar ankle replacement prosthesis (10) which includes a first metal plate (12) that can be fixed to the tibia, a second metal plate (14) that can be fixed to the talus and an intermediate element (16) of moulded plastics which can be located between the metal plates. The second metal plate has a superior surface (34) which curves convexly and relatively sharply in a sagittal plane and concavely and relatively gently in a frontal plane. The intermediate element has corresponding curvatures on its inferior surface to enable the element to slide congruently, in mutually orthogonal directions, over the second metal plate.
