Damage to the hyaline cartilage of the articular surface is often irreversible, and it is generally recommended to take glucosamine sulfate and chondroitin sulfate when cartilage is damaged. Because they are components of the extracellular matrix of cartilage, they can improve the metabolism of articular cartilage cells, i.e., promote the anabolic metabolism of cartilage cells and inhibit the catabolism of cartilage cells, increase the components of the articular cartilage matrix, and in some respects, increase the content of proteoglycans in cartilage and increase the thickness of the cartilage layer. In addition to nourishing joint cartilage, glucosamine sulfate and chondroitin sulfate have the effect of inhibiting inflammation and relieving pain. In addition, intra-articular injections of sodium vitrate can be given to reduce cartilage wear and ease the process of cartilage degeneration.
