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.
