Abstract:
1. A prosthetic system for performing the function of a knee joint, comprising: a tibial component having a tibial plateau and a tibial stem portion, the tibial plateau having a top side and a bottom side; a post having a proximal end and a distal end, the post adapted to project from the top side of the tibial plateau; a tibial insert having an aperture, the tibial insert adapted to be positioned on the top side of the tibial plateau with the tibial insert aperture adapted to receive the post; a femoral component having a base portion and a central housing having a femoral stem portion, the base portion having a pair of condyles and two posteriorly extending lobes; a mechanical linkage for connecting the tibial component and the femoral component, the mechanical linkage comprising: an axle adapted to connect to the lobes and extend between the lobes; and a link having an anterior end and a posterior end, the link adapted to be connected to the axle at the posterior link end and to receive the post at the anterior link end; wherein, when the mechanical linkage connects the tibial component and the femoral component, the mechanical linkage provides for movement of the link along a superior-inferior axis relative to the post, and the mechanical linkage constrains movement of the link relative to the tibial component in a superior direction along the inferior-superior axis.
