Abstract
Degenerative osteoarthritis is recognized as the consequences of
mechanical injuries. The abnormal impact force applied to articular
cartilage would result in bone fracture or surface fissuring, and would
cause the osteoarthritis [1,2]. The relation among the injury and impact
energy was well studied. However, how the external energy
attenuated to the internal joint is not carefully studied yet. The porcine
knee joint was used as a biomechanical model for the simulation of
human knee joint during impact loading. The objective of current
study was to find the variation of kinetic characteristics between
human and porcine knee joint during axial impact loading. Eight
fresh-frozen knee joints from 10 month-old swine and seven cadaver
human knee joints were used in the experiment. The mechanical
responses such as forces and bending moment of knee joint, and the
accelerations of femur was quantitatively analyzed. The results
showed that the axial force response between human and porcine
joints was similar, however, the anteroposterior shear, flexion bening
moment and accelerations of these two joints were different.
