ABSTRACT:
A knee replacement system includes a femoral component including a lateral condylar articulating portion and a medial condylar articulating portion, a tibial tray including an upper articulating surface, and a tibial insert including (i) a first articulating portion for articulating with the lateral condylar articulating portion with a first condylar dwell point, (ii) a second articulating portion for articulating with the medial condylar articulating portion with a second condylar dwell point, (iii) a lower articulating surface for articulating with the upper articulating surface, and (iv) a coupling member for coupling with the tibial tray and defining an axis of rotation about which the tibial insert rotates with respect to the tibial tray, the axis of rotation intersecting the upper articulating surface at a location posterior to a dwell axis including the condylar dwell points when the dwell axis is projected onto the upper articulating surface.
