摘要:
Arthroplasty components include an articular surface and a bone-facing surface. In some examples, the bone-facing surface bears at least one anchoring element adapted for an oblique implantation trajectory. The anchoring element includes a reinforcement plate, a dowel, and surface features. Each surface feature resists forces acting along a different direction. In other examples, the bone-facing surface bears anchoring elements that deform along the primary or longest axis of the anchoring element during insertion. In yet other examples, the bone-facing surface is enlarged relative to the articular surface so that at least a portion of the perimeter of the articular surface is circumscribed by the perimeter of the bone-facing surface.
