In daily life, many patients prefer brisk walking and jogging, both of which can cause damage to the knee. Because both brisk walking and jogging are done with weight on the patient, they can put pressure on the knee joint, and prolonged exercise can cause damage to the meniscus, synovium, or muscles and muscle groups of the knee joint, resulting in pain. Especially if the patient is suffering from osteoarthritis, after brisk walking or jogging, it will aggravate the degree of osteoarthritis. Therefore, patients with knee pain should try to avoid brisk walking and jogging exercises and can do swimming exercises. Swimming is a better way to exercise because it is weightless and does not stimulate pressure on the joints. In addition, patients who have symptoms of knee discomfort should seek medical attention in a timely manner, and after examination by a doctor, the cause of the disease should be clarified and treatment should be taken.
