1. A hinged orthopaedic knee prosthesis system, comprising:
a femoral component configured to be attached to a distal end of a patient's femur;
a tibial tray configured to be attached to a proximal end of a patient's tibia, the tibial tray including a curved outer wall;
a tibial insert configured to be positioned between the femoral component and the tibial tray, the tibial insert including a platform, an elongated stem that extends inferiorly from a distal surface of the platform, and a posterior component removably coupled to a posterior side of the platform, wherein the posterior component includes an inferiorly-extending tab that is configured to engage the curved outer wall of the tibial tray to limit rotation of the tibial insert relative to the tibial tray about a first axis extending in an inferior-superior direction,
wherein the femoral component is coupled to the tibial insert and configured to rotate, relative to the tibial insert and over a range of motion, about a second axis substantially orthogonal to the first axis.
