An orthopaedic prosthetic assembly includes a femoral component configured to be attached to a distal end of a patient's femur. A tibial tray is configured to be attached to a proximal end of a patient's tibia. A tibial insert is provided that includes a spine extending proximally from a body, and a pin hole extending through the spine. A bushing is sized and shaped to be positioned in the pin hole of the spine. A hinge pin is sized and shaped to be positioned in the bushing to couple the tibial insert to the femoral component. The bushing includes a retaining tab configured to engage an inner wall of the pin hole to secure the bushing to the spine.
