Finite Element Analysis of the Porous Coating in Hip-Joint Prosthesis
The finite element model of the cementless femoral stem was used to calculate the main stresses of the bone-implant interface. Assuming the rigid contact between porous coating and bone tissue, three different implant designs were analyzed: smooth shape implant, implant with two porous inserts and w...

Summary: | The finite element model of the cementless femoral stem was used to calculate the main stresses of the bone-implant interface. Assuming the rigid contact between porous coating and bone tissue, three different implant designs were analyzed: smooth shape implant, implant with two porous inserts and when 2/3 of the implant was coated by the porous titanium. Results showed that enlargement of the porous coating increases the stresses within proximal femur and reduces the stresses in diaphysis. |
