| Outline of Final Research Achievements |
The purpose of this study was to evaluate stress distribution within the anterior cruciate ligament (ACL) and impingement against the femoral intercondylar notch, using finite element analysis. Three-dimensional knee models were simulated rotation of the tibia, valgus, and anterior tibial translation. High stress distribution and impingement of the ACL on the femoral intercondylar notch were found the knee joint position under inner rotation of the tibia, valgus, and anterior tibial translation. An anterior - superior force induces the tibial translation. Quadriceps contraction during jump landing and the resulting anterior tibial shear force were simulated with few parameters. This finite element analysis showed that strong stress occurred at ACL when the knee under internal rotation, valgus, and anterior tibial translation.
