Abstract: A knee prosthesis (e.g., a tibial implant or component) is disclosed. In one embodiment, the tibial implant includes a load bearing component (e.g., a tibial tray) and a support member arranged and configured to be at least partially positioned within an intramedullary canal of a patient's bone. In some embodiments, the tibial implant may also include one or more pegs positioned anteriorly on a bottom surface of the tray and one or more bridges for coupling the pegs to the support member so that loads received by the pegs are transferred to the support member via the bridge. In addition, and/or alternatively, the tibial implant may include one or more chamfers or loading zones for elongating the transition area between the support member and the bottom surface of the tibial tray to extend the area over which the load is transferred.

Abstract: A proximal femur replacement implant assembly (500, 1000) arranged and configured to replace a head portion of a patient's proximal femur is disclosed. In some examples, the proximal femur replacement implant assembly includes a proximal femur replacement implant (505, 1005) arranged and configured to be coupled to, or inserted into an intramedullary canal of, a remaining portion of a patient's femur. The proximal femur replacement implant being arranged and configured to engage a bone plate (510, 1010, 1050) to, for example, minimize micromotion of the patient's greater trochanter to promote porous in-growth and to constrain movement of the greater trochanter.

Abstract: There are provided herein methods and products resulting therefrom. The methods include attaching a pre-fabricated porous ingrowth structure to a substrate by applying heat, or creating and bonding an in-situ-formed porous ingrowth structure from beads on a substrate by applying heat. In some embodiments, an oxidized metal surface of the substrate is diffusion hardened during the heating process. In some embodiments, a vacuum is applied during the heating process. In some embodiments, pressure is applied during the heating process. Also provided herein are assemblies for compressing the pre-fabricated porous ingrowth structure or the beads onto the substrate during the heating process.
