Paragraph Number

183

Advantageously, the knee prosthesis system 3000 can remediate an undesirable or unacceptable tibiofemoral rotation within the medial tibial compartment during flexion of the knee joint. Specifically, the tibial articulation surface 2412 facilitates tibiofemoral rotation within the medial tibial compartment 2413 during flexion of a first knee joint where the condition is a valgus knee joint. In the illustrated embodiment, the surgeon may choose, either pre-operatively and/or intraoperatively, to use tibial insert 2910b with the tibial baseplate component 2840 and the femoral component 2801 for a right knee. The tibial insert 2910b is positioned between the tibial baseplate component 2840 and the femoral component 2801 when deployed, see arrow 3012. The tibial insert 2910b may be used instead of the tibial insert 2910a because the right knee presents a valgus condition.
