Bone Mineral Density (mean ± SD) in Contralateral, Saline, HA and Hybrid groups. a subchondral bone plate BMD (Pt.BMD); b trabecular bone BMD (Tb.BMD), c subchondral bone plate TMD (Pt.TMD); d trabecular bone TMD (Tb.TMD). #, * and ∆ indicate statistical significance under pairwise Mann-Whitney-Wilcoxon Rank test (α = 0.05) compared to Contralateral-group, Saline-group and HA-group, respectively, performed after significant Kruskall-Wallis ANOVA test (α = 0.05)
