Implant
First Claim
1. An implant for placing on a plateau or resection surface of a joint bone, comprising:
- at least one skidshaped cup having a joint seating surface, a ventral and a dorsal end, the joint seating surface extending in a longitudinal direction and having first and second curvature radii, the first curvature radius being transverse to the longitudinal direction and, at least in a coronal area, being larger than the second curvature radius transverse to the longitudinal direction and in an area, which is loaded when the joint is fully bent, wherein the first curvature radius continuously merges into the second curvature radius within a transitional area which extends over an angular range between about 30° and
about 70°

Abstract
An implant for placing on a plateau or resection surface of a joint bone includes at least one skidshaped cup having a joint seating surface, a ventral and a dorsal end. The joint seating surface extends in a longitudinal direction and has first and second curvature radii. The first curvature radius is transverse to the longitudinal direction and, at least in a coronal area, larger than the second curvature radius transverse to the longitudinal direction and in an area, which is loaded when the joint is fully bent. The first curvature radius continuously merges into the second curvature radius within a transitional area which extends over an angular range between about 30° and about 70°.
