Femur bone shape in OpenSim (just like other bones) is too coarse and doesn't match a patient-specific CT-based bone model, in detail even when it is scaled.
Muscle Force Direction plugin gives you muscle attachment points and lines of action for scaled osim model while neither bone geometry nor muscle attachment points may necessarily be the same among osim model and CT-based FE model,
so how would you recruit this plugin to get accurate results?
Regards.

bones in OpenSim are just for visualization purpose.
You need a data set to scale it to your patient.
data sets built on cadaver dissections and imaging.
there are several ways to scale a data set to your patients.
linear scaling using MOCAP data.
non-linear scaling.
morphing techniques.
