In Vivo Study of Ligament-Bone Healing after Anterior Cruciate Ligament Reconstruction Using Autologous Tendons with Mesenchymal Stem Cells Affinity Peptide Conjugated Electrospun Nanofibrous Scaffold
Histological assessment of ligament-bone insertion at 1 and 3 months after reconstruction surgery. H-E staining indicated connective tissues growing in ligament-bone insertion of control group, PLLA reconstruction group, and BIO reconstruction group at 1 month ((a)–(c)) and 3 months ((d)–(f)). Magnification: 200x. T: tendon; B: bone; FS: fibrous synovium; FC: fibrocartilage; S: Sharpey’s fiber; UFC: uncalcified fibrocartilage; CFC: calcified fibrocartilage; TM: tide line mark.
