Anterior cruciate ligament (ACL) disruption is a common injury that is detrimental to an athlete’s quality of life. Determining the mechanisms that cause ACL injury is important in order to develop proper interventions. This study was conducted to provide insight into the specific knee orientations associated with ACL injuries. A failure locus for the ACL was developed by simulating multiple loading scenarios using a 3-D finite element analysis (FEA) model of the knee. The results indicated varus and valgus were more dominant to the ACL injury compared to femoral rotation. The order of MCL failure, ACL failure, and maximum meniscus stress was also determined with respect to time during loading. The results of this study could be used to develop training programs focused on the avoidance of the described combination of movements, which may lead to ACL injury.

This paper will take five male patients who performed a double-bundle anterior cruciate ligament (ACL) reconstruction to do finite element analysis and compare the stress distributions with each other. In order to lead this paper to reality, a model of the original bone tunnel according to CT is created and transformed into a finite-element model based on the reverse engineering method. The double-bundle ACL graft in the bone tunnel simulates the interference screw which screwed the ACL under the limit of friction and fix of contact. The dynamic analysis is performed with the femur flexion-extension axis which is under the limit of a fixed rotation angle (100°) and two degrees of freedom of motion in flexion. In the postprocess, the ACL graft is divided into several parts to get the stress distribution which will be easily to discuss the results. The result shows that max stress can be found on the top of the ACL or at the start point of the ACL because of the fixed position of the interference screw. The stress in PL bundle is greater than the stress in AM bundle. The angle of flexion will affect the stress and the stress might be higher at a specific angle.
