[A mathematical model of determining the knee joint injury].
A mathematical model of determining the injury of human knee joint was established by using structural dynamics method. The results showvered the corresponding shearing displacement and bending angle of the knee joint on the occasion of ligament avulsion, and the shearing force and bending moment which caused tibial condylar fractures under purest shearing and bending condition. The calculated results consisted with the experimental results greatly, suggesting that using mathematical method to determine the injury is feasible and this kind of method can do good to lots of subjects, such as pedestrian protection, athletic medicine and rehabilitation engineering.
