Paragraph Number

126

The asymmetry of the insert 2410, and particularly the medial ramp 2419, may cause greater translation of the medial dwell point 2435 compared to the lateral dwell point 2436. The medial dwell point 2436 translation, alone or in conjunction with lateral dwell point 2435 translation, causes or allows tibiofemoral rotation similar to that of a natural knee. Tibiofemoral rotation in a natural knee is the outward rotation of the tibia and lower leg relative to the femur in flexion. In natural tibiofemoral rotation, the toes point outward in flexion compared to extension. The degree of medial dwell point 2435 translation may correspond to rotation of the tibial baseplate component 2440 and insert 2410 relative to the femoral component 2401.
