ASYMMETRIC TIBIAL COMPONENTS FOR A KNEE PROSTHESIS

An orthopaedic tibial prosthesis includes a tibial baseplate with an asymmetric periphery (200) 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 asy...

Beschreibung
Zusammenfassung:	An orthopaedic tibial prosthesis includes a tibial baseplate with an asymmetric periphery (200) 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.
