A tibial prosthesis comprising:
- a tibial tray having a medial-lateral center and an inferior surface matable with a resected proximal tibia;
- and
- a modular keel comprising a tray mating portion and a keel portion, the keel portion having a plurality of wing elements suitable for anchoring the keel within the proximal tibia, the tray mating portion being fixable to the inferior surface and adjustable in a medial-lateral direction with respect to the medial-lateral center of the tibial tray to allow medial-lateral adjustment of the keel portion with respect to the tray.
A tibial prosthesis comprising:
- a tibial tray having a medial-lateral center, an inferior surface matable with a resected proximal tibia, two or more slots extending in a medial-lateral direction, and two or more mating elements extending through the two or more slots;
- a modular keel fixable to the inferior surface and adjustable in a medial-lateral direction with respect to the medial-lateral center of the tibial tray;
- wherein the two or more mating elements extend through the two or more slots to secure the modular keel to the tibial tray and fix the medial-lateral position of the keel with respect to the tibial tray.
