TABLE 2.

Changes in reaction force [%] at the bone/ground interface for P500, P1000 and full density CoCrMo and Ti alloys scaffolds under compression, with respect to that in the full bone (no scaffold). The changes were estimated via FEA (first two columns) and using the analytical spring-based model (last column).

	Δ reaction force FE-based model		Δ reaction force Spring-based model
	Ti6Al4V	CoCrMo	CoCrMo
Full density scaffold	−41.2%	−44.1%	−88.9%
P500 scaffold	−34.4%	−39.6%	−72.7%
P1000 scaffold	−18.2%	−27.7%	−34.6%
