In patients with wear and tear of the articular surface, the edema and roughness of the articular cartilage surface is caused by excessive stress on the articular surface. In this case, first of all, avoid excessive weight-bearing, flexion and extension activities in the joint area, so as not to cause repeated compression and friction on the cartilage surface, resulting in increased wear. After wear and tear, you can apply hot compresses to the joint or apply blood-stasis-boosting drugs to promote blood circulation in the joint, thus promoting the recovery of the worn joint. If necessary, cartilage nutrient drugs such as sulfuric acid or glucosamine hydrochloride can be added orally to promote the repair of the cartilage surface of the worn joint. If necessary, joint cavity puncture and injection of sodium vitrate, a nutritional lubricant, can also be used to restore the worn joint surface.
