Sports medicine is often associated with soft tissue injuries,with tendon and ligament injuries being the most common sports injuries accounting for 30％-40％of all injuries.Mesenchymal stem cell exosomes have the ability to escape phagocytosis and realize long-term circulation,and can also be used as drug carriers of biological materials.The use of exosomes derived from mesenchymal stem cells for cell-free treatment of soft tissue injury is the current research direction in sports medicine.In this paper,the origin of exosomes in soft tissue regeneration is summarized,with emphasis on the biological mechanism of exosomes in soft tissue injury and the progress of diagnosis and treatment related to biomaterial.
