An anatomically based mathematical model of the passive constraints, including both surface contacts and ligaments and based on screw theory, is presented as a method of assessing the instantaneous total freedom of the knee. Screw theory address the full three-dimensional kinematics and allows consideration of motions that release or violate constraints. Models for the ligamentous and articular surface constraints are proposed and procedures for formulating and solving model equations are presented.<>
