TABLE 1.

The first two columns report the FE-based estimation of stiffness for the P1000, P500 and full density metal scaffolds in Ti and CoCrMo alloys. The third column shows the stiffness of the CoCrMo scaffolds estimated via Equation 1 (full density scaffolds and bone) and Equation 2 (porous scaffolds).

	FE-based stiffness [kN/mm]		Analytical stiffness [kN/mm]
	Ti6Al4V	CoCrMo	CoCrMo
P1000 scaffold	68.5	119.9	82.7
P500 scaffold	190.4	333.5	288.0
Full density scaffold	427.9	800.3	799.8
Cortical bovine bone	32.0		32.0
