Abstract: BACKGROUND: Irregular structures on the nanometer scale mimic the structure of natural extracellular matrix molecules, and can be used as a carrier for cell adhesion or proliferation to promote tissue regeneration at the site of implantation. 
OBJECTIVE: To review the research progress of nanomaterial artificial ligament applied in ligament reconstruction.
METHODS: Computer was used to search CNKI, PubMed, Web of Science, Embase, Cqvip and Wanfang databases. The search terms were “tissue engineering, nanomaterials, artificial ligaments, nanometre, nanoscale, artificial ligament”. According to the standard, the research progress of nanomaterial artificial ligament was included in the literature. 
RESULTS AND CONCLUSION: Nanomaterials have good biological compatibility. Artificial ligaments modified by nanomaterials can provide good adhesion environment for cells and promote cell proliferation. Bone marrow mesenchymal stem cells can proliferate and differentiate on the surface of artificial ligaments modified by nanomaterials and promote the extension of bone into ligaments. This effect enhances the strength of ligaments and promotes tendon and bone healing to a certain extent. Nanomaterial scaffold is a promising solution for the treatment of ligament injuries. The current nanofiber preparation technology has laid the foundation for the implementation of this solution. Currently, the prepared nanofibers can provide ideal mechanical strength, and some nanomaterials are degradable. After implantation, they can promote the proliferation of fibroblasts and gradually replace the nanofibers until ligament regeneration is achieved. The research of nanomaterial scaffold has also made some progress in bone connection and anti-adhesion.
