Bone Mesenchymal Stem Cells Contribute to Ligament Regeneration and Graft–Bone Healing after Anterior Cruciate Ligament Reconstruction with Silk–Collagen Scaffold

Figure 8

Russell–Movat staining of the graft–bone interface. At 4 weeks after the reconstruction surgery, no obvious bone integration was noticed in the two groups (a, b). At week 16, the mature trabecular bone could be noticed at the graft–bone interface in the S group (c), whereas in the S/C group, osteointegration with the trabecular bone into the graft was observed (d). g: graft; b: bone; if: interface.
