Patent number: 8758444Abstract: 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: GrantFiled: August 23, 2012Date of Patent: June 24, 2014Assignee: Zimmer, Inc.Inventors: Mary S. S. Wentorf, Calie B. Grey, Shaun R. Cronin

Publication number: 20140025175Abstract: 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.Type: ApplicationFiled: September 24, 2013Publication date: January 23, 2014Applicant: Zimmer, Inc.Inventors: Mary S.S. Wentorf, Jeffrey E. Bischoff, Raymond C. Parisi, Katherine M. Rettig
