A prosthetic knee system includes a tibial tray, a non-rotating tibial
insert, and a rotating tibial insert. The non-rotating tibial insert and
the rotating tibial insert are selectively couplable to the tibial tray
such that a fixed or a mobile orthopaedic prosthesis may be configured.
In some embodiments, the tibial tray may be a fixed or mobile tibial
tray. Additionally, in some embodiments, the prosthetic knee system may
include a femoral component.
