  • Patent number: 8758444
    Abstract: An orthopaedic knee prosthesis is provided including a tibial baseplate component having a distal, bone-contacting surface with one or more fixation structures extending distally therefrom, in which the fixation structures are asymmetrically arranged within the baseplate periphery.
    Type: Grant
    Filed: August 23, 2012
    Date of Patent: June 24, 2014
    Assignee: Zimmer, Inc.
    Inventors: Mary S. S. Wentorf, Calie B. Grey, Shaun R. Cronin
  • Publication number: 20140025175
    Abstract: An orthopaedic tibial prosthesis includes a tibial baseplate with an asymmetric periphery which promotes proper positioning and orientation on a resected tibia, while also facilitating enhanced kinematics, soft-tissue interaction, and long-term fixation of the complete knee prosthesis. The asymmetric baseplate periphery is sized and shaped to substantially match portions of the periphery of a typical resected proximal tibial surface, such that proper location and orientation is evident by resting the baseplate on the tibia. The baseplate periphery provides strategically positioned relief and/or clearance between the baseplate periphery and bone periphery, such as in the posterior-medial portion to prevent deep-flexion component impingement, and in the anterior-lateral portion to avoid undue interaction between the anatomic iliotibial band and prosthesis components.

  • Publication number: 20130204383
    Abstract: A family of tibial baseplates can comprise a plurality of tibial baseplates. Each of the plurality of tibial baseplates can define a common nominal baseplate size and a unique, non-congruent tibial baseplate periphery as compared to the other tibial baseplates of the family of tibial baseplates.

  • Publication number: 20130024001
    Abstract: An orthopaedic tibial prosthesis includes a tibial baseplate with features designed for use with small-stature knee-replacement patients. The tibial prosthesis may include a shortened tibial keel, tibial keel fins which define a large angle with respect to a longitudinal axis of the keel, and/or tibial keel fins which extend along less than the entire longitudinal extent of the keel.
