Résumé :	Total knee arthroplasty (TKA) is a medical procedure that aims to restore the functions of the knee by replacing it by an artificial joint. The main challenge for a successful TKA is to provide stability and restore the range of motion of the native knee. To achieve this, different approaches are commonly used by surgeons. The central matter of debate is the alignment, which is related to the tibial cut before inserting the tibial component of the prosthesis. Indeed, some surgeons cut the tibia perpendicular to the tibial plateau, which is called mechanical alignment, while others prefer to cut it with a 3° angle to rebuild the natural joint angle between the tibial plateau and the femoral condyles. This second approach is referred as kinematic alignment. The purpose of this study is to investigate how the alignment and the configuration affect the stress distribution and kinematics at two regions of interest: the tibiofemoral prosthesis interface and the prosthesis-bone interface. A finite element analysis was performed on four previously validated models under daily activities: walking and squat. The results expected should show which alignment and configuration are the best options in terms of stability and motion restitution.
