- 論文の詳細を見る
The mechanical movement of the knee joint is analysed by the tibio-femoral, tibio-menisco-femoral and patello-femoral contact using the silicon rubber embossment.The movement of the knee joint consists of three major phases from the functional point of view.(1) Hinge Phase The range of motion over 60 degree of flexion where the the femoral condyle slips on the tibial table.(2) Rolling Phase The range of motion from 15 to 60 degree of flexion where the femoral condyle rolls over the tibial table with some different slipping factor in both condyles.(3) Screw Home Phase The range of motion from full extension to 15 degree of flexion where the lateral condyle glides on the tibial table which is a pivotal turn while the medial condyle rolls over the tibial table.
