Although many biomechanical studies have been addressed the shock absorption function of menisci on a knee joint, few reports concerning the behavior of menisci under the impact loading condition are presented. In this study, the impact compression test using the normal porcine knee joint was performed in order to observe the visco-elastic behavior of the meniscus by the high-speed video camera. As a result, the normal meniscus showed the typical visco-elastic property under the high strain rate of meniscus for the dynamic stress. This fact indicated the meniscus could not possess excellent shock-absorbing against the high impact energy to knee joint.
