Abstract:  
ABSTRACT A work hardened articulating surface for anatomical prosthetics. Articulating surfaces of prosthetics are work hardened to decrease the wear and increase the longevity of the prosthetic after implanation. The aritculating surface can be hardened in any number of ways, for example the articulating surface can be formed from stock material that has been work hardened throughout or the articulating surface can be work hardened prior to final finishing of the prosthetic component. Regardless, the hardened articulating surface reduces wear after implantation while eliminating the need for a separate bearing component.
