Abstract

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 coupleable 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.
