System of inserts for the tibial component of a knee prosthesis

摘要

A plurality of various shaped wedges, each wedge having an upper and lower face, each face including a plurality of spaced aligned protrusions adapted to engage a plurality of channels formed in the under surface of the tibial base, the protrusions registering with the channels to allow positioning of the wedge relative to the shape of the tibial component in various positions along the edge of the component, so that the plurality of wedges may be positioned to align themselves with the edge of the tibial component, and therefore in addition to providing a spacer between the bone and the undersurface of the component, to be secured within the same confined area as the component.
