Summary of surface roughness values for FSC and articulated samples.

	Ra (nm)	SRz (μm)	Rsk (nm)	PV (μm)
FSC	0.477 +/−0.045	1.41 +/− 0.147	0.327 +/− 0.117	7.50 +/− 1.09
MoC	0.522 +/− 0.066	2.76 +/− 0.284^**	0.505 +/− 0.163	10.75 +/− 0.706
CoC	0.428 +/− 0.047	2.19 +/− 0.283	0.536 +/− 0.359	10.76 +/− 1.35

Ra: Arithmetical mean deviation roughness, SRz: Average radial peak-to-valley areal roughness, Rsk: areal skewness of the roughness (positive skew indicates a predominance of peaks), and PV: peak to valley difference. Data represents means +/− SEM for n=10–12 explants.
