abstract = { objective:Three  dimensional  digital  modeling  of  human  knee  joint  is  carried  out,  and  the 
mechanical behavior of knee joint in landing impact motion is analyzed by finite element method, which 
provides  a  reasonable  basis  for  prevention  of  knee  joint  sports  injury.Methods:  three  dimensional 
geometric model of knee joint was reconstructed by software Mimics;Transforming 3D geometric model 
into  3D  finite  element  model  by  3-matic  software;The  finite  element  software  ANSYS  was  used  to 
analyze the stress and strain of the cruciate ligament, tibial cartilage and meniscus in different impact 
motions.Results  and  conclusion:1.  jumping  and  landing  impact  moment,  knee  cartilage,  ligament, 
meniscus stress increases with the increase of the height of jumping, the tibia, the average distribution of 
the lateral platform landing impact load, the stress is greater than the anterior cruciate ligament posterior 
cruciate ligament, jumping height is 66cm, should be the force of posterior cruciate ligament in very close 
to the maximum, suggesting jumping height greater than 66cm in normal life or race training is easy to 
damage the posterior cruciate ligament.2, the posterior cruciate ligament with limited internal rotation of 
the femur in knee function, under the situation that internal rotation of the femur or tibia external rotation 
may damage the posterior cruciate ligament.
