Elderly knee cartilage wear refers to the meniscus wear of the knee joint of the elderly, and the treatment modes include general treatment, medication and surgery. 1. General treatment: minimize squatting and activities such as walking up and down stairs and hiking to reduce meniscus wear. If you are heavy, you can reduce your weight appropriately. 2. Drug treatment: local injection of sodium vitrate into the knee joint can be used to lubricate the knee joint, and drugs that nourish the cartilage, such as glucosamine sulfate capsules, can be used. 3. Surgery: If conservative treatment has no effect, meniscus wear and tear is serious, knee pain seriously affects daily life, or even paralysis, surgery can be considered. If knee pain occurs in old age, if the pain persists without relief, it is recommended to consult a doctor in time and follow the doctor’s instructions.
