Abstract

In this study the geometric and material properties of joint surfaces, bones, ligaments of the tibio-femoral joint is represented and passive knee flexion is simulated. The purpose of the study is to observe the effect of 11° tibial slope to the tibio-femoral movement. The contact forces between tibia and femur are defined as frictionless mathematical model. Tibial plateaus and condyles of femur are represented as ellipsoids as described in literature. Anterior, posterior cruciate ligaments, medial, lateral collateral ligaments are represented as non linear elastic springs. Knee flexion with and without internal-external torque are simulated, and the results are compared with the literature for slopped and flattened medial tibial plateau models. As a result, normal internal rotation of tibia and adduction ranges are achieved for unloaded condition in flattened model, but the knee flexion with forced internal/external rotation are out of normal range for both models.
