Patients with osteoarthritis should reduce joint load and excessive movements, and obese patients should pay attention to weight loss to avoid aggravating cartilage damage. When symptoms are severe, a cane can be used to alleviate the burden on the joints. In terms of diet, one can eat more foods rich in vitamins, mainly various vegetables and fruits, and also consume foods high in calcium appropriately. Patients with arthritis should also pay attention to protecting the joint areas, and guard against cold and dampness to avoid exacerbating symptoms. When symptoms are severe, medication can also be used for treatment, such as anti-inflammatory analgesics and drugs that nourish cartilage, which can play a role in improving symptoms and delaying the progression of the disease. When mobility is impaired, surgical treatment might be necessary.
