1. A method of replacing a distal femur, comprising:
removing a first femoral prosthesis previously implanted on the distal femur;
forming a bone void at an end of the distal femur;
inserting a void filling prosthesis into the bone void such that a body of the void filling prosthesis is positioned within the bone void and legs of the void filling prosthesis extending from the body are positioned entirely within the bone void, the body including an opening that extends through a sidewall of the body along an entire length of the body; and
implanting an intramedullary stem of a second femoral prosthesis through the opening that extends through the body and onto the distal femur after inserting the void filling prosthesis into the bone void.
