Caractérisation de la cinématique du genou : identifier les effets de différents paramètres sur la cinématique du genou en utilisant la modélisation

Abstract : Knee kinematic is complex. It depends of geometric parameters and mechanical parameters. Geometric parameters are mainly defined by bone geometry, articular surfaces and by several soft tissues insertions. Mechanical parameters are defined by soft tissues characteristics designed by laws which link distances between their insertions and generated forces. Muscles, tendons, and ligaments are characterized by linear stiffness and pre-load at one specific position of knee joint: full extension. This work analyzes with rigid-body simulation tool, the knee joint comportment. First part of this work describes model construction. Second part places model inside external loads and constrains. Third part shows model results and compares them to several bibliographies. Last and forth part tests several values of each mechanical parameter. This part evaluates influence of parameter to knee kinematic. Synthesis of results helps to show most influent parameters on internal/external rotation of tibia relative to femur and on femur anterior/posterior displacement during knee flexion movement.
