1. An implantable orthopaedic device, comprising:
a component made from a polymeric material, wherein the polymeric material has a crystallinity gradient formed therein and
the crystallinity gradient is positioned such that the crystallinity of the polymeric material increases moving in a direction
away from an exterior surface of the polymeric material toward an interior of the polymeric material.
