Abstract:
Virtual knee models have been created over the years to study artificial
knee components in a simulated anatomic environment similar to
physical knee simulators. The kinematics of a fixed bearing PFC
Sigma® cruciate-retaining total knee (DePuy, Warsaw, IN) was
examined in a virtual knee simulator throughout one cycle of deep knee
bending. Rollback of the femur relative to the tibia and internal rotation
of the tibia relative to the femur were compared as a function of knee
flexion angle for different values of the patellar tendon coronal-plane
angle.
