Abstract：
The biomechanical analysis of human femur was carried out, and the compressive properties of porous alumina ceramic scaffolds were analyzed by finite element method. The results show that the static stress of femur is 7.2 MPa when the body weight is 65 kg. Taking 7.2 MPa as the external load of femur implantation, finite element analysis is carried out.The A33 model with 69.7% porosity and 620 microns diameter is obtained through the comparison and analysis of the compression performance with the single-hole configuration model with different pore diameters and porosity.
