Development and validation of a human knee joint finite element model for tissue stress and strain predictions during exercise

Abstract

ABSTRACT

The effects of knee joint kinematics on anterior cruciate ligament injury and articular cartilage damage

“…This is beneficial as modeling the subject specific muscular forces is complex and inaccurate. Material properties for the various tissues included in our model were taken from several recent publications which have been used and validated in several simulation based studies (Blankevoort et al 1991;Puso et al 1998;Haut Donohue 2002;Fung and Zhang 2003;Haut Donahue et al 2003;Peña et al 2006;Yang et al 2010a;Wangerin 2013;Kiapour et al 2014). It is known that ACL injury and cartilage damage will change the material properties of these soft tissues.…”

“…Previous studies have used 3D FE knee joint models to investigate the stress and strain fields in knee joint tissues under various loading conditions (Gardiner and Weiss 2003;Limbert 2004;Mesfar and Shirazi-Adl 2006;Peña et al 2006;Papaioannou et al 2008Papaioannou et al , 2010Boyd et al 2012;Wangerin 2013;Kiapour et al 2014;Wang et al 2014). Soft tissue injury was not investigated in any of these studies.…”

Development of a Human Tibiofemoral Joint Finite Element Model to Investigate the Effects of Obesity and Knee Malalignment on Joint Contact Pressure

“…The articular cartilage meshes were then analyzed consecutively in the tibiofemoral FE model. Finite element simulations for mesh convergence were accomplished by prescribing the knee flexion angle to 10.5 and applying the forces and moments listed in Table 7, which are physiologically consistent for a normal weight individual at this particular phase of gait [51]. Boundary conditions and loads were applied as described in the previous sections.…”

Development and Validation of a Tibiofemoral Joint Finite Element Model and Subsequent Gait Analysis of Intact ACL and ACL Deficient Individuals

“…The loading and BCs used were typical knee forces, moments and flexion angles seen during gait [89] applied to the KJC. For the articular cartilage, the nodes in the node set tracked contact pressure as the mesh density increased, while the nodes in the node set for the ACL bundles and BPTB graft tracked the maximum principal stress.…”
