This review comprehensively summarizes the current status and cutting-edge techniques of tendon allograft processing.The core of tendon allograft processing procedures is outlined,systematically summarizing the research status and advanced technologies in this field.Tendon allografting has become one of the main methods for tendon injury reconstruction.Initially,the application background and de-velopmental trends of tendons allograft are introduced,followed by an in-depth discussion on physical cryopreservation and chemical meth-ods related to immunogenicity and rejection reactions,as well as processing techniques such as defatting and decellularization.Emphasis is placed on the importance of optimizing tendon allograft processing techniques to enhance clinical surgical outcomes,providing scientific evi-dence and technological support for its clinical application.
