| Abstract |
To reveal the characteristics of knee movement
and tibio‐femoral joint contact force, a novel single
degree of freedom spatial mechanism is built to
simulate the joint kinematics based on a three
dimensional model of the human knee. The length
changes of the three ligaments can be obtained by
establishing and solving the kinematics spiral function.
Based on this mechanism, a static model is built where
linear springs are used to model the ligaments and
whose stiffness coefficients are obtained by the finite
element method. The main strength of the proposed
model is that it associates the knee’s flexion motion with
internal/external rotation of the tibia based on the
isometricity of the anterior cruciate ligament. This offers
an efficient method to model and analyse the changes of
ligament lengths and static kinematics after ligament
reconstruction, which is crucial in designing knee
recovery and rehabilitation equipment. |
