Methods of using implant devices are provided herein. The implant devices of the methods herein 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.
