Abstract

This invention relates to shanks for knee joint endoprostheses which, on implantation, are inserted in a space prepared in the spongiose and marrow of the receiving bone. The invention consists in matching the external contour of the shank for at least a part of its length to the cross-section of the medullar cavity in a normal human bone receiving the shank.
