HE staining smear results of the femoral head in each group at different time points, group A had the largest number of fat cells and the thinnest, bone trabeculae under the femoral head. Bone trabeculae in group B and group C gradually thickened. Group D is the thickest. At 8 weeks, the bone trabeculae in group A were the thinnest and the fat cells were the most filled. The trabeculae in group D were the thickest. At 12 weeks, group A had necrosis of articular surface, sparse subchondral bone, and many empty bone lacunae. Group B and C were relatively improved, but the articular surface of group C was thinner and broken than that of group D. The articular cartilage surface of group D was normal and thick, and the empty bone lacunae were the least.(: Bone trabeculae; ༚The articular cartilage).
