Lateral view radiographs of ten autopsy knees were used to determine the orientation of the patellar ligament, patella and quadriceps tendon relative to tibia and femur at different flexion-extension angles (0-120 degrees) of the knee. The results show a linear relationship between the angle of flexion and the movement of the patellar ligament relative to the tibia and of the movement of the patella relative to tibia and femur. There is a non-linear relationship between angle of flexion and the movement of the quadriceps tendon relative to the patellar ligament, patella and femur. The angular changes between patella and patellar ligament are negligible. The complicated movements of the distal part of the quadriceps femoris muscle may significantly influence biomechanical parameters such as the forces acting at the patella and tibial tuberosity.
使用十个经尸检的膝关节的侧位X线片来确定在膝关节不同屈伸角度（0-120度）下髌韧带、髌骨和股四头肌肌腱相对于胫骨和股骨的方向。结果显示，屈曲角度与髌韧带相对于胫骨的移动以及髌骨相对于胫骨和股骨的移动之间存在线性关系。屈曲角度与股四头肌肌腱相对于髌韧带、髌骨和股骨的移动之间存在非线性关系。髌骨与髌韧带之间的角度变化可忽略不计。股四头肌远端的复杂运动可能会显著影响生物力学参数，如作用于髌骨和胫骨结节的力。
