Figure 10. μ-CT evaluation of the subchondral bone at the tibial plateau in the OA model rats. (A) Representative images show the 3D μ-CT coronal views of the right knee and axial view of ROI from blank control, OA and experimental group rats. (B) Histogram plots show the analysis of trabecular structure analysis, including bone volume/tissue volume (BV/TV), trabecular number (Tb. N) and trabecular separation (Tb. Sp)in the blank control, OA and experimental group rats. *p < 0.05 compared with the control group; ns: not significant compared with the OA group.
