主权项

1. A low friction resurfacing implant system comprising:
a first implant component comprising a first bearing surface and a first engagement surface located opposite the first bearing surface, wherein the first implant component has a leading edge and a trailing edge, wherein the first implant component comprises teeth that extend from the first engagement surface, wherein the teeth are arranged in a plurality of rows, wherein teeth in adjacent rows are offset from each other, wherein the first implant component further comprises a first opposing side and a second opposing side, wherein the first opposing side and the second opposing side each extend between the leading edge and the trailing edge and wherein the teeth comprise:
a first set of teeth proximate the first opposing side, wherein the first set of teeth each have an exterior face that faces the first opposing side and an interior face that faces the second opposing side;a second set of teeth proximate the second opposing side, wherein the second set of teeth is oriented differently than the first set of teeth and wherein the second set of teeth each have an exterior face that faces the second opposing side and an interior face that faces the first opposing side; anda third set of teeth between the first set of teeth and the second set of teeth, wherein the third set of teeth is oriented differently than the first set of teeth and the second set of teeth, wherein:
the first set of teeth comprises at least two rows of teeth, wherein the teeth in adjacent rows are offset from each other; andthe second set of teeth comprises at least two rows of teeth, wherein the teeth in adjacent rows are offset from each other.
