摘要： A tibial component of a prosthetic knee implant has a tibial tray, a post extending axially downwardly from a generally laterally central location beneath the tibial tray, and a keel including flanges extending laterally outwardly from the post and making an angle with one another so as to be directed toward relatively denser portions of the bone of the proximal tibia, and a plurality of ribs extending axially along each flange and spaced laterally from one another along the flange for enhancing the affixation and stability of the tibial component when implanted in the proximal tibia. Apparatus for preparing the proximal tibia for the reception of the tibial component includes a tibial punch and a tower selectively located at the proximal tibia, the tower having an axially extending guide bushing for placement above the proximal tibia and a channel extending laterally into the guide bushing for enabling the tibial punch to be inserted laterally into the guide bushing and then moved axially downwardly into the proximal tibia, while guided by the guide bushing, to establish a cavity in the proximal tibia for reception of the tibial component.

摘要： An intramedullary alignment rod for properly orienting and supporting a cutting guide or tool has a complex geometry which includes at least two differently sized sections, the smaller of which is at the proximal end of the rod. The complex geometry of the rod maximizes the rigidity of the rod while avoiding the trauma of an interference fit, and facilitates stabilization of the intramedullary rod in the medullary canal.

摘要： A modular component for a prosthetic implant includes a first member, in the form of a tibial tray member, and a second member, in the form of a stem member, joined together by the insertion of a tapered post on the stem member into a tapered receptacle in the tibial tray member, the relative tapers and relative dimensions of the post and the receptacle being such that the inner surface of the receptacle is seated against the outer surface of the post at least adjacent one end of the receptacle and the corresponding end of the post, and a stabilizing mechanism urges annular segments of the post, adjacent the other end of the post, toward engagement with the inner surface of the receptacle adjacent the corresponding other end of the receptacle to stabilize the connection between the tibial tray member and the stem member.
