Abstract:
1. A family of tibial prostheses sized for attachment to a proximal tibia, the family comprising: a plurality of tibial prostheses defining a plurality of prosthesis peripheries, each said prosthesis periphery defining: a posterior-lateral distance extending from said centroid to a posterior-lateral corner of said prosthesis periphery; said plurality of prosthesis peripheries including: said second posterior-medial growth larger than said first posterior-medial growth, and said second posterior-lateral growth larger than said first posterior-lateral growth, whereby said plurality of tibial prostheses exhibit non-linear, asymmetric growth in medial and lateral posterior corners of said prosthesis peripheries as sizes of said tibial prostheses consecutively increase, wherein said plurality of tibial prostheses comprises a plurality of tibial baseplates, in combination with a plurality of tibial bearing components, each of said plurality of tibial bearing components comprising: a lateral portion which substantially corresponds to said prosthesis periphery for said lateral compartment of one of said plurality of tibial prostheses, and a medial portion which is at least partially incongruent with said prosthesis periphery for said medial compartment of one of said plurality of tibial prostheses.
