    Abstract: A knee replacement system, and a method for supplying and implanting a knee replacement system, for enabling natural knee movement in a leg in a patient, including: a medial femoral component having a medial femoral articulating surface with a sagittal plane profile including four medial femoral arcuate portions scaled by a first femoral scaling factor; a lateral femoral component having a lateral femoral articulating surface with a sagittal plane profile including four lateral femoral arcuate portions scaled by a second femoral scaling factor; a medial tibial component having a medial tibial articulating surface that articulates with the medial femoral articulating surface and includes a first raised medial edge that increases in width in an anterior direction; and a lateral tibial component having a lateral tibial articulating surface that articulates with the lateral femoral articulating surface and includes a second raised medial edge that increases in width in the anterior direction.

    Abstract: A femoral hip prosthesis is provided with porous bony ingrowth material on each of the anterior and posterior sides. The bone ingrowth materials on each side flare or expand outwardly in the proximal direction with respect to the sides of the prosthesis, to provide a wedge shaped configuration of at least 1 millimeter increase in thickness at the upper proximal end of the porous materials from the point where the expansion begins. By impacting the prosthesis in the surgically prepared opening in the femoral canal a wedge tight fitting is achieved to assure initial stabilization of the prosthesis for a sufficiently long period of time, e.g. about six weeks or more, until bony ingrowth into the porous materials has occurred to provide long term stabilization. The distal end of the stem of the prosthesis is chamfered anteriorly and posteriorly so that the prosthesis can be used for either the right leg femur or left leg femur without impinging on the anterior bow.
