The purposes of this study were to investigate the relationship between the relative tibiofemoral movement estimated with the point cluster technique and kinetics of the knee joint during normal walking, and to investigate relationships between the walking speed and the relative tibiofemoral movement or kinetics of the knee joint during prescript walking. Three cadences were made synchronous with three rhythms (Slow, Medium, and Fast) of the metronome during prescript walking. There were correspondences between three directions (Flexion-Extension, External-Internal, and Anterior-Posterior) of the tibiofemoral movement and directions of respective intersegmental forces and moments during stance phase. But there was not necessarily the correspondence through all of stance phase. Stable mechanism of the knee joint, so-called "screw home movement", was identified during three timings of the normal walking cycle. It was found that peak values of tibiofemoral movement and knee joint kinetics were increasing with increasing walking speed. These results suggested that changing the walking speed would influence tibiofemoral movement and kinetics of the knee joint.
