The purpose of this project is to provide an open source, discrete element knee model.

License: Knee Model Version 1

This project implements a discrete element knee model in OpenSim. Specifically, the model is a six degree-of-freedom tibiofemoral and one degree-of-freedom patellofemoral joint. It includes eighteen ligament bundles and tibiofemoral contact and was validated against cadaveric data.
