A joint replacement assembly including a male component seating within a female component and a pattern of microgrooves defined in an articulating surface associated with at least one of the components. A volume of a lubricant is maintained in an evenly distributed fashion across the articulating surface in order to provide at least one of reduced friction, increased wear life, and elimination of squeaking or acoustical emissions. The microgrooves can exhibit any of a plurality of intersecting and enclosed profiles, a plurality of overlapping and undulating patterns, an intersecting grid pattern, and a plurality of isolated profiles. Other shapes include a concave depression cross sectional profile, each of which can further exhibit a central upward projection associated with the concave depression. |
