Abstract: A joint prosthesis may include a tibial tray, a tibial base, a tibial articular member, and a femoral articular member. A coupler may engage the tray, and optionally the base, with an interference fit. An interference fit may be engaged using a mating surface with a constant non-tapering cross-sectional geometry.

Abstract: A air root pruning container for plants includes a side wall made of a plurality of segments extending in layers above a base wall with each segment having a larger radius as measured from a central axis than the subjacent segment and with the segments being separated from adjacent segments to provide air root pruning openings between the segments; each segment includes outwardly curved wall portions so that the interior wall surfaces will guide root development to an opening.

Abstract: The certification display has a multilayer matting board including similarly sized first and second matting layers. The first matting layer is connected in coextensive overlaying relation to a front surface of the second matting layer. The multilayer matting board provides a predetermined location for the placement of a certification document or diploma and recertification labels. A certificate aperture for viewing a certificate, diploma or other certification documents extends through the matting board. The certificate aperture has a sufficient depth to act as a spacer between a front cover and the face of the certificate or diploma. A certificate, diploma, or other documentation is mounted on a back surface of the second matting layer in registry with the certificate aperture. A plurality of label wells extends through the first layer of the matting board. A recertification label is placed within the label wells, typically adhered to the bottom of the label well.
