General view (A) and cross-sectional view (B) of the femoral condyles of rabbit osteochondral defect model in CTL, SF, Cu@SF, TA@SF and CuTA@SF at 12 weeks after surgery. The residue hydrogels were marked by an asterisk. (C) Three-dimensional reconstruction images of three planes (coronal, axial, sagittal) using the micro-CT data of CTL, SF, Cu@SF, TA@SF and CuTA@SF. The green color stands for newly formed subchondral bone. Bone mass analysis of the obtained samples with quantitative micro-CT for (D) bone mineral density (BMD), (E) bone volume/total volume (BV/TV), (F) trabecular numbers (Tb. N) and (G) trabecular thickness (Tb. Th). Results were shown as mean ± SD, *p < 0.05, **p < 0.01, ***p < 0.001.
