Constitutive
''in situ'' strain
Description
The zero force reference lengths (or "slack length") of the ligamentous knee structures have been shown to be important contributors to overall joint mechanics. As they are difficult to measure, ligament slack lengths are a commonly targeted parameter during optimization of specimen-specific joint level kinetic-kinematic response. Regardless of the level of refinement in the modeling approach, whether continuum or spring based, a parameter based representation facilitates these iterative studies.
