We proposed a statics-based model to predict knee adduction/abduction moment, which is a major mechanism of anterior cruciate ligament (ACL) injury. Our model neglects the dynamic terms of equation of motion because, at the time of ACL injury, the moment of ground reaction force (GRF) is much more dominant than the moment caused by shank's inertia and gyroscopic torque. As a result of experiment, the statics model well agreed with the Newton-Euler method, indicating that the knee adduction/abduction moment is mainly determined by the moment of GRF. For the kinematics-based moment prediction, the accuracy of the estimated GRF, which was calculated from the acceleration of body center of mass, was also assessed. A possible application of this study may be the risk determination of ACL injury by analyzing the real injury videos.
