The sample model is a simplified representation of femur-anterior cruciate ligament-tibia based on Open Knee(s) - Generation 1 (version g1-s1-v1.1.0.391).

Synopsis

This simulation and related scripts are utilized for the demonstration of cloud computing with Open Knee(s) and derivative models. The sample model is a simplified representation of femur-anterior cruciate ligament-tibia based on Open Knee(s) - Generation 1 (version g1-s1-v1.1.0.391). The model includes femur and tibia as rigid bodies and anterior cruciate ligament as a deformable body with same constitutive properties as described for Open Knee(s) - Generation 1 model. Tibia is fixed, femur motion is prescribed using a clinically based joint coordinate system. Finite element analysis, using FEBio version 2.5.0, predicts resultant tibiofemoral joint forces, from which the anterior cruciate force is calculated. Femur kinematics at the final and intermediate steps of simulation are processed to report the resultant tibiofemoral joint kinematics in a clinically relevant manner. Raw simulation results, including anterior cruciate ligament stresses and strains, can be accessed through the FEBio output file (.xplt) using PostView (distributed at http://febio.org/). Simulations should complete within a few minutes assuming target movement pattern is physiological.
