Objective:
To study the biomechanical response and the role of articular surface on the femur-tibia model under impact loading of the body weight.
Methods:
A three-dimensional finite element (FE) model of the femur-tibia composite was reconstructed using the image data of the knee joint of Virtual Chinese Human No.1 Male, and FE calculation was performed to simulate the impact of the body weight on the knee joint while walking.
Results:
The femur-tibia composite was compressed during the impact with obvious protrusive movement. Diffusion and attenuation of the stress occurred during its conduction to the articular surface.
Conclusion:
The femur-tibia composite is unstable under the vertical impact loading of the body weight, with obvious protraction movement, and the articular surface may serve as the buffer of the impact.
