Abstract:

A tibial prosthesis comprises a medial base portion configured to engage a medial surface of a tibia and a lateral base portion configured to engage a lateral surface of the tibia. At least a portion of the medial and lateral base portions are separated by a passage interposed therebetween. The tibial prosthesis also comprises a bridge coupling the medial base portion and the lateral base portion, wherein at least a portion of the bridge is elevated above a portion of the passage between the medial base portion and the lateral base portion. The bridge may define an underlying area that receives at least a portion of a tibial eminence when the tibial prosthesis is engaged with the tibia, wherein the height of the bridge varies in a superior direction across the passage.
