GAIT CYCLE 3-D CAD MODEL LOAD ANALYSIS OF HUMAN KNEE JOINT FEMUR

biomedical engineering

Knee joint is a very complex structure in the body which is an indispensable part during variety of locomotion’s carried out in a lifetime of a human being .It can take place from standing, walking and running to doing variety of mechanical work. However, gait cycle analysis primarily focuses on studying the motion of leg through cyclic divisions or stride and step of two multi-segmented body limbs and total body mass. Major part in knee joint is femur, tibia, patella and meniscus. It has two articulation or we may say rotating portion between femur and patella. Knee joint is a flexible joint which permits rotation in variety of ways and direction. In the distal end of femur there is a possibility of a horse- shoe shaped bend in front end of the femur. The two ends of the femur extend backward and forward and are called medial and lateral condyles . Knee joint is blended and flexed to compensate for incongruence of bone in motion. In this experiment we have primarily focused on stress, strain, displacement and load calculation mainly for, femur at pressure angle in x, y and z direction of the plane.
