Artificial tibial component for partial or unicondylar bearing knee replacement, method for selecting such artificial tibial component, method for implanting such artificial tibial component, and kit for surgeon
The invention concerns a tibial prosthetic component comprising a plate (100) for forming a tibial plateau of a tibia (16), wherein a peripheral region of the plate (100) has a thickness of less than 3mm. The invention also concerns a tibial prosthetic component having a keel of depth less than 9mm. The invention also concerns a method of selecting a tibial prosthetic component comprising receiving measurements of at least one physical attribute of an individual into whom the tibial prosthetic component is to be implanted, selecting a thickness of a plate (100) and depth of keel of the tibial prosthetic component based on the measurements and providing a tibial prosthetic component comprising a plate (100) having the selected thickness and a keel having the selected depth. The invention may also comprise implanting a tibial prosthetic component selected in accordance with this method into an individual and a kit comprising a plurality of prosthetic components comprising plates having different thicknesses with keels of different depths.
