A prosthesis (10) for replacing the proximal end of a tibia, installable without bone cement which includes a tibial plateau portion adapted to receive an articulation insert. Integral with the underside of the plateau (14) is an intermedullary fixation stem (16) to which is attached a medial-lateral fin (17). Attached to each end of the fin is a transverse fin (18, 20) which provides a dual "T" configuration, which provides superior anchoring of the prosthesis.
