Artificial implants having reduced area to provide reduced wear are provided. The reduced area is particularly located at areas where greatest wear is exhibited. In a particular embodiment of a mobile bearing knee implant, the area is reduced on the mobile bearing insert underside, where it contacts a tibial component. The reduced area may be any shape of indentations, for example, grooves, dimples, straight patterns, curved patterns, crossing patterns, holes, channels or slots. The indentations may be various sizes, and have been found to be particularly effective if covering about 10% to about 20% of the insert at depths between about 1-2 mm.
