Computational biodynamics of human knee joint in gait: From muscle forces to cartilage stresses

A multi-scale finite element model for investigation of chondrocyte mechanics in normal and medial meniscectomy human knee joint during walking

“…Based on our preliminary simulations, the internal-external moment presented in Kutzner et al (2010) was reduced by 90% to match experimentally observed ranges of internal-external rotation ( $ 101) (Benoit et al, 2006;Kadaba et al, 1990;Kozanek et al, 2009;Reinschmidt et al, 1997). This was also supported by another study suggesting that passive internal-external moment of the knee is about 10-20% from the measured knee moments (Adouni et al, 2012).…”

A multi-scale elasto-plastic model of articular cartilage

“…The plug of articular cartilage was represented by cylindrical model that included the depth-dependent changes in fibril orientation. The cartilage sample morphology followed the three-layered structure with depth-dependent fibril orientation and collagen fibril volume fraction proposed by previous studies(Adouni et al, 2012; Shirazi and Shirazi-Adl, 2008;Wilson et al, 2004) (Fig.1). To reflect the incompressibility of the articular cartilage during the transient (short-term)…”

Role of Ligaments in the Knee Joint Kinematic Behavior: Development and Validation of a Finite Element Model

“…Several finite element (FE) knee models have also been developed in an effort to comprehensively investigate various aspects of knee mechanics including contact pressure under various loads [12][13][14][15][16][17][18], ligament stress [19][20][21], or the dynamic behavior [14,22,23]. A few of them studied knee kinematics [12,14,24,25].…”

“…A few of them studied knee kinematics [12,14,24,25]. The high numerical costs associated with the computation of the biomechanical response of the knee joint and the full validation of these models against tibio-femoral and tibio-patellar kinematic data, however, are still a main issue [14], particularly for patellofemoral motion because of uncertainty in patellar tracking.…”
