Generic OpenSim models such as the Rajagopal model [1] have questionable biofidelity as they are comprised of a single degree of freedom (dof) knee joint while the remaining five degrees are prescribed based on in vitro cadaver work. To enhance the validity of these models, magnetic resonance imaging (MRI) can be incorporated to satisfy appropriate patient-specific bone geometry, muscle wrapping, and ligament lengths. The purpose of this study was to evaluate kinematics and ligament lengths when adapting the Rajagopal model to include an MRI-based knee contact model.

Abstract
Generic OpenSim models such as the Rajagopal model [1] have questionable biofidelity as they are comprised of a single degree of freedom (dof) knee joint while the remaining five degrees are prescribed based on in vitro cadaver work. To enhance the validity of these models, magnetic resonance imaging (MRI) can be incorporated to satisfy appropriate patient-specific bone geometry, muscle wrapping, and ligament lengths. The purpose of this study was to evaluate kinematics and ligament lengths when adapting the Rajagopal model to include an MRI-based knee contact model.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
