A total ankle replacement prosthesis may comprise a tibial implant, a talar implant, and an intermediate implant. The intermediate implant may fixedly attach to the tibial implant and may articulate with respect to the talar implant. The intermediate implant may have unequal front and back angular extent, so as to discourage a particular direction of subluxation, and a kit may be provided containing various such intermediate implants. Various features may be provided in regard to dovetails, fins, recesses, the placement of fins and pegs, and the shape of the perimeter of the tibial implant. Recesses may allow a surgical blade to slice a latch off of an already-installed intermediate implant, in order to allow its removal from the tibial implant.
