Knee degrees of freedom

Hi
I want to ask how much degrees of freedom the knee has.Some knee osteoarthritis patients may have more than one degree of freedom during walking.Can the knee joint open more degrees of freedom in the Anybody? And the correct inverse dynamics analysis can be performed.Thank you in advance.

Best wishes

Hi, zzs

The normal human knee joint has 6 DOFs.
The AnyBody Modeling System assumes the Knee joint as a hinge joint which only has one DOF (Flexion and Extension) by default.

You can open more DOFs using FDK methods. https://anyscript.org/tutorials/ForceDependentKinematics/index.html
