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

Figure 9

Representative micro-CT images. Few mineralized tissues were detected at the graft–bone interface at 4 weeks postoperatively (a, S group; b, S/C group). At 16 weeks postoperatively, distinct signals appeared indicating new mineralized tissue regeneration at the graft–bone interface of each group (c, S group; d, S/C group). The mineralized tissue signal and average bone tunnel area may indicate bone integration at the graft–bone interface.
