Abstract
Systems and methods for providing deeper knee flexion capabilities, more physiologic load bearing and improved patellar tracking for knee prosthesis patients. Such systems and methods include a tibial component for replacing at least part of a proximal portion of a tibia. In some cases, the tibial component includes an articulation feature that forms a projection that projects from a posterior portion of at least one of a medial articulation surface and a lateral articulation surface of the tibial component. In some cases, the articulation feature is contained within an area of the tibial component that is selected from a lateral portion which is lateral to a medial-most portion of an intercondylar surface, and a medial portion, which is medial to a lateral-most portion of the intercondylar surface, and wherein the intercondylar surface is disposed on an object selected from the tibial component and the proximal portion of the tibia. While the tibial component can replace both the medial and lateral articulation surfaces, in some cases, the tibial component is a unicompartmental component. Other implementations are also described.
