Claim 14:
15. An orthopaedic knee prosthesis comprising:
a femoral component having a lateral condyle and a medial condyle, wherein the medial condyle includes a femoral articular surface defined by a plurality of curved femoral surface sections that includes a first curved femoral surface section defined by a continually decreasing radius of curvature; and
a tibial insert having a lateral articular surface configured to articulate with the lateral condyle of the femoral component and a medial articular surface configured to articulate with the medial condyle of the femoral component,
wherein the lateral articular surface includes an arcuate articular path extending in an anterior-posterior direction, wherein the arcuate articular path when viewed in a cross-section plane has a curvature that includes a planar section and wherein the planar section defines a distal-most area of the lateral articular surface, and
wherein the medial articular surface is asymmetrically shaped relative to the lateral articular surface and includes a medial dwell point that defines a distal-most point of the medial condyle surface, and wherein the medial dwell point is located on the medial condyle surface (i) between a first imaginary medial-lateral bisecting line of the tibial insert that includes an anterior-most end of the planar section of the sagittal curvature of the lateral articular surface and a second imaginary medial-lateral bisecting line of the tibial insert that includes a posterior-most end of the planar section of the sagittal curvature of the lateral articular surface and (ii) posterior to an anterior-posterior midpoint of the planar section of the sagittal curvature of the lateral articular surface.
