Simulating Instrumented Knee Implant Forces With a Simplified Computational Model Available to Purchase

A simplified computational model is presented with which axial knee implant forces can be estimated. The dataset provided in the IV Grand Challenge to Predict in-vivo Knee Loads [1] is used to assemble a musculoskeletal model, and perform an inverse dynamics analysis. The joint and muscle dynamics recorded during the inverse analysis is then used as target values during a forward dynamics analysis to compute the axial tibiofemoral load.
