Claim Text:
1. An ankle prosthesis comprising: a talar implant; a tibial implant; an intermediate implant designed to be interposed between the tibial implant and the talar implant, the intermediate implant being designed to be mounted to move relative to the talar implant in order to impart mobility to an ankle; and embedded adjustment means for modifying an assembly configuration of the intermediate implant relative to the tibial implant, the adjustment means alternatable between a releasing state, in which they allow the intermediate implant to move relative to the tibial implant with at least first and second degrees of freedom that are distinct from each other, and a locking state, in which they inhibit the first and second degrees of freedom so as to hold the prosthesis in the chosen assembly configuration; wherein the adjustment means are placed under control of control means that are accessibly disposed along an anteroposterior axis and are operable while the prosthesis is in the assembled state in vivo, so as to cause the adjustment means to alternate between their releasing state and their locking state.
