Microarchitectural parameters (mean ± SD) in Contralateral, Saline, HA and Hybrid groups. a subchondral bone plate thickness (Pt.Th); b trabecular thickness (Tb.Th); c trabecular separation (Tb.Sp); d trabecular bone volume fraction (Tb.BV/TV). #, * 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)
