  • Tibial bearing component for a knee prosthesis with improved articular characteristics
    Patent number: 9072607
    Abstract: An orthopaedic knee prosthesis includes a tibial bearing component with articular features which operate to protect adjacent soft tissues of the natural knee, promote and/or accommodate desired articulation with an abutting femoral component, and facilitate expedient and effective implantation by a surgeon.
    Type: Grant
    Filed: April 27, 2012
    Date of Patent: July 7, 2015
    Assignee: Zimmer, Inc.
    Inventors: Raymond C. Parisi, Abraham P. Habegger, Jeff C. Blaylock, Dwight T. Todd
  • Tibial bearing component for a knee prosthesis with improved articular characteristics
    Patent number: 8858643
    Abstract: An orthopaedic knee prosthesis includes a tibial bearing component with surface features which operate to protect adjacent soft tissues of the natural knee throughout a wide range of flexion. More particularly, the tibial bearing component provides an anterior relief space disposed between the dished lateral and medial articular compartments, in which the relief space is convex as viewed from a sagittal perspective across the medial/lateral extent of the relief space.
    Type: Grant
    Filed: April 27, 2012
    Date of Patent: October 14, 2014
    Assignee: Zimmer, Inc.

  • Motion facilitating tibial components for a knee prosthesis
    Patent number: 8591594
    Abstract: An orthopaedic tibial prosthesis includes a tibial baseplate sized and shaped to cover substantially all of a resected proximal tibial surface, and a tibial bearing component sized to leave a posteromedial portion of the tibial baseplate exposed when the tibial bearing component is mounted to the baseplate. The exposed posteromedial portion of the tibial baseplate includes a chamfered profile which cooperates with a correspondingly chamfered profile at a posteromedial edge of the tibial bearing component to create a substantially continuous chamfer extending from the resected tibial surface to the medial articular surface of the tibial bearing component. Advantageously, this chamfer leaves an absence of material (i.e., a relief or void) at the posteromedial edge of the tibial prosthesis, thereby enabling deep flexion of the prosthesis without impingement between the tibial prosthesis and adjacent anatomic tissues or prosthetic structures.
