Comparison of the maximum tensile strengths. The adhesion of bone cement to a stainless steel surface was verified by determining the tensile strength of metal–bone cement interfaces. The maximum tensile strengths were measured for three different roughness: mechanically polished (R a = 0.42 ± 0.12 µm), glass blasted (R a = 0.78 ± 0.10 µm) or corundum blasted (R a = 1.2 ± 0.2 µm) stainless steel surfaces. Mean values ± standard deviation of the measured values are presented (N = 5) (Kruskal–Wallis, *p < 0.05).
