摘要: The invention provides an ankle prosthesis for use in the field of orthopedic prostheses comprising a talus implant for implanting in or on the talus and a top element including a tibia implant for implanting in or on the base of the tibia. The top element and the talus implant being mounted to move relative to each other by friction on a contact interface so as to allow the ankle to move. The contact interface presents a friction surface that can be considered as being a fraction of a substantially frustoconical surface. When implanted, the substantially frustoconical surface is oriented so that its larger radius portion is directed substantially towards the outside of the ankle.
