Anterior cruciate ligament (ACL) injuries have been increasing throughout the years and close to one billion dollars are spent annually on such injuries. Women are 4 to 6 times more susceptible to ACL injuries than men. Researchers have proposed risk factors that are related to the higher incident rates. However, there currently isnÂ’t enough research to verify these risk factors. It is important to find prevention methods to reduce the instances of ACL injuries. The goal of this project is to examine how two risk factors (ligament size and quadriceps angle) affect the ACL during sidestep cutting. A 3D finite element model of the ACL was developed in ANSYS and combinations of loads are applied. The stresses on the modeled ACL was then examined and evaluated.
