Tibial prosthetic component for a partial or unicondylar meniscal bearing knee replacement,method of selecting such a tibial prosthetic component

摘要

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 3 mm. The invention also concerns a tibial prosthetic component having a keel of depth less than 9 mm. 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.
