This project aims to reconstruct the passive flexion motion of the knee based on anatomical data alone, which includes bony anatomy, cartilage geometry and ligament insertion sites geometry. Current knowledge of ligament behavior and articular contact mechanics has been mainly based on anatomical and mechanical data from cadaveric studies along with computational models of the knee joint. In current knee modeling techniques, mechanical properties of soft tissues, are either adopted from literature or estimated through the involved inverse modeling approach that relies on experimental measurements of the joint kinematics. Thus, modeling results are tied to the quality of the collected data, which is always susceptible to errors. The ability to predict joint kinematics without the need to collect kinematics-kinetics data is a groundbreaking mean which can be easily translated into a clinical setting or other applications.
