| Abstract: | By means of X-ray Photo measurement and STK video analyzing system the biomechanics characteristics of the knee joint motion were studied quantitatively.The maximum range of motions of the knee joints in dynamic and static states as well as the changes of the length and the arm of force of the muscles participating in knee joint motions were measured.It was considered that there were no sex differences in mechanic structures of the knee joints.The extent of the muscular participation and the sequence to reach the maximum arm of force were pointed out. |

| Keywords: | knee joint maximum range of motion absolute lenght change relative length change maxi-mum arm of force |
