Synopsis
The overall goal of this case study is to provide the utility of Open Knee(s) specimen-specific data - for evaluating mechanical function of the cruciate complex (anterior and posterior cruciate ligaments).
Use Case
The case is aimed at building a compartmental model of the cruciate complex using comprehensive specimen-specific data for one of the Open Knee(s) specimens. The goal is to develop kinematically driven model of the cruciate complex to evaluate the crutiate response under various loading conditions. This will also be helpful in developing a pipeline for model development using the geometric, joint and tissue mechanical information for a given knee joint. Effects of tissue geometry, insertion sites of the ligaments, material properties etc can then be evaluated on the cruciate complex mechanics (simulating effect of reconstruction surgeries).
Simulation Aims
- To build a finite element model of the cruciate complex supported by specimen-specific joint geometry, joint mechanical data and tissue properties.
- Develop list of specifications to build specimen-specific finite element model of a joint.
- Evaluate cruciate response under various geometric and mechanical conditions.
