Abstract
A knee prosthesis in which articular surface areas of the engaged femoral and tibial components of the prosthesis include surface profile contours lying in a common arcuate profile defined by a medial-lateral radius having an origin lying on the mechanical axis passing through the femoral head of the corresponding hip joint such that limited misalignment of the femoral and tibial components by virtue of angular deviation from the mechanical axis resulting from relative displacement in a medial-lateral direction is tolerated to accommodate the misalignment while maintaining area engagement between the engaged surfaces.
