  • Patent number: 9216201
    Abstract: The present invention provides a composition for regenerating cartilage or treating a cartilage disease containing a monovalent metal salt of alginic acid for which the endotoxin level thereof has been lowered to an extent that does not substantially induce inflammation or fever. As a result, it is possible to provide a composition for regenerating cartilage that improves cartilage regenerative action and ease of application to a cartilage injury lesion, and a composition for treating a cartilage disease, which has the effects of protecting cartilage from mechanical irritation, inhibiting degenerative changes in cartilage caused by wear and inflammation, repairing a cartilage injury lesion, and inhibiting inflammation and pain of joint tissue.
