Proper exercise can be beneficial for patients with knee pain. Exercise helps relieve joint pain and stiffness, strengthens the muscles around the joints, and helps maintain joint flexibility and mobility. However, it is important for patients with knee pain to choose the appropriate type and intensity of exercise, such as biking, walking and swimming are suitable exercises, while hiking and running are not. Life is about exercise, and it is not correct to simply stay away from any exercise, especially for middle-aged and elderly people who are aging and often have a combination of systemic diseases such as hypertension and diabetes. Of course, for patients with knee pain, it is important to seek early medical attention to identify the cause of the pain and make the appropriate diagnosis and treatment. Long-term chronic pain not only leads to aggravation of local conditions, but also to depression, which affects mental health and quality of life.
