Book excerpt: The objective of this study was to develop a dynamic three-dimensional subject-specific computational knee model and to validate the model using experimental data from a dynamic knee simulator. Experimental testing was performed on the specimen knee in the Kansas Knee Simulator (KKS) under various loading profiles and the kinematics of the knee were recorded. A model of the knee in the KKS was created using specimen bone geometrics and techniques were developed to accurately model soft tissue contacts, ligament behavior, and basic ligament and tendon bone wrapping. The experimental and model simulation kinematics from a ten second squat cycle, five second walk cycle, six second laxity cycle, and a ten second walk cycle with a transected anterior cruciate ligament (ACL) were compared for validation. Reasonable correlation between experimental data and that obtained from the model simulations validated modeling techniques developed.
