Outline of Final Research Achievements

We need to clarify the function of normal knee ligaments under the loading condition in order to develop an artificial knee joint. The purpose of study is to measure the distance between femoral and tibial footprint of the ACL and PCL during Squat motion in normal knees under normal loading condition using the biometric image matching technique and to investigate the length pattern of these distances. Additionally, we investigated length pattern changes as a result of differences in the femoral footprint. Our results showed that the difference of femoral footprint leads to different tension. Moreover, Small bundles is functioning in a complementary manner.
