Osteoarthritis is a chronic degenerative joint disease that is generally associated with age, joint strain, obesity, joint trauma, and certain medications, and occurs in the knee, hip, and spine joints. Osteoarthritis is mainly characterized by slow progression of joint pain and stiffness, with most patients experiencing significant pain or increased pain in the morning or during prolonged immobility, with slight relief after a little activity. In some cases, the diseased joints suddenly appear to be “locked” after sitting for a long time and cannot be moved. In advanced stages of the disease, as the cartilage in the joint degenerates and peels off, the bone under the cartilage is exposed, and when moving, the bones at both ends rub against each other, resulting in a clicking sound or a sense of friction. In conclusion, patients with osteoarthritis should avoid strain, reduce excessive joint activity, reduce weight bearing on the joints, and if they are overweight, it is recommended that they first reduce their weight in order to help slow down the progression of the disease and receive systematic treatment in hospital if necessary.
