Figure 1

Estrogen deficiency leads to LFJ subchondral bone collapse. (A) Representative 3-dimensional and 2-dimensional micro-CT images of the LFJ subchondral bone in different groups. Abundant subchondral bone cavities (green and blue arrows) are shown in OVX and OVX+ vehicle (Veh)-treated groups. (B) Superior bone volume/tissue volume (BV/TV) of LFJ subchondral bone. (C) Inferior BV/TV of LFJ subchondral bone. (D) LFJ subchondral bone cavity numbers in different groups. (E) LFJ subchondral bone maximum diameters in different groups. Key: *P < 0.05, **P < 0.01, ***P < 0.001, (N.S.) not significant.
