An implantable knee prosthesis includes a body having a substantially elliptical
shape in plan and a pair of opposed faces. A peripheral edge of variable thickness
extends between the faces and includes a first side, a second side opposite the
first side, a first end and a second end opposite the first end. The thickness
of the peripheral edge at the first side is greater than the thickness of the peripheral
edge at the second side, the first end and the second end.
