Three-dimensional (3D) micro-computed tomography (micro-CT) images of the subchondral bone in the ovariectomized/destabilization of the medial meniscus (OVX/DMM) rat group with and without estrogen (E2) and <t>raloxifene</t> (RAL) treatment and the control group. ( A ) Severe bone erosion, cyst formation, and bone sclerosis are shown in the OVX/DMM group. ( B ) Near-normal subchondral bone in the OVX/DMM+E2 group. ( C ) The subchondral bone shows osteoporosis and the bone structure is destroyed in the OVX/DMM+RAL group. ( D–F ) The degree of osteoporosis in the subchondral bone was increased.

Figure Lengend Snippet: Three-dimensional (3D) micro-computed tomography (micro-CT) images of the subchondral bone in the ovariectomized/destabilization of the medial meniscus (OVX/DMM) rat group with and without estrogen (E2) and raloxifene (RAL) treatment and the control group. ( A ) Severe bone erosion, cyst formation, and bone sclerosis are shown in the OVX/DMM group. ( B ) Near-normal subchondral bone in the OVX/DMM+E2 group. ( C ) The subchondral bone shows osteoporosis and the bone structure is destroyed in the OVX/DMM+RAL group. ( D–F ) The degree of osteoporosis in the subchondral bone was increased.

Article Snippet: Two months after the models were successfully established, rats were injected with estrogen (0.1mg/kg/day) (Sigma-Aldrich, St. Louis MO, USA) or raloxifene (3mg/kg/day) (MedChem Express, Monmouth Junction, NJ, USA) for one month.

Techniques: Micro-CT, Control

The bone mineral density (BMD) of the subchondral bone at 0, 2, and 4 weeks after surgery. Compared with the control group, the ovariectomized/destabilization of the medial meniscus (OVX/DMM) rat group, the OVX/DMM+estrogen (E2) group, and the raloxifene (RAL) treated group all show a loss of bone mass. Maintenance of bone mass showed no significant difference between the OA group and the OVX/DMM+RAL group, but the OVX/DMM+E2 group show significant improvement in bone mass (* P<0.05, ** P<0.01).
