1. ) An implant comprising:
- an articular end having an upper surface, a side surface, and a lower surface;
the upper surface and lower surface each intersect the side surface, the upper surface has a first surface curvature, a central surface curvature, and a second surface curvature; and
an oval-shaped stem, which extends from the lower surface in a direction away from the upper surface of the articular end.

Abstract
Implant devices, and method of using the same, are provided. The implant devices have an articular end and a stem, the stem having an oval-shaped cross-section. The articular end has an upper surface, a side surface, and a lower surface. The upper surface and lower surface each intersect the side surface. The upper surface has a first surface curvature, a central surface curvature, and a second surface curvature. The stem extends from the lower surface in a direction away from the upper surface of the articular end.

18. ) A method of repairing articular cartilage comprising:
-
locating articular cartilage having a lesion; utilizing an implant having dimensions compatible with the lesion, wherein the implant comprises; an articular end having an upper surface, a side surface, and a lower surface; the upper surface and lower surface each intersect the side surface, the upper surface has a first surface curvature, a central surface curvature, and a second surface curvature; and an oval-shaped stem, which extends from the lower surface in a direction away from the upper surface of the articular end; forming a cavity in the articular cartilage, subchondral bone, and cancellous bone; and engaging the implant with the cavity so that the lower and side surfaces of the articular end abuts against the subchondral and cancellous bone and the stem abuts against the cancellous bone. - View Dependent Claims (19, 20)
