1. Proper joint movement and total joint movement can stimulate all parts of the articular surface of the patella, and the nutrients in synovial fluid can penetrate into the cartilage tissue evenly, thus enhancing the lubrication of the joint.

2. Don't do strenuous exercise, such as climbing mountains and stairs. Avoid sudden changes in exercise intensity, and the activities to enhance strength and endurance should be gradual and gradually increased.

3. Keeping a proper weight can reduce the gravity acting on the knee joint. Obesity will increase the risk of degenerative diseases of the knee joint and form a vicious circle. The greater the weight, the heavier the pain; Conversely, the lighter the weight, the lighter the pain.

4. It is best not to wear high heels. When walking or running, wear shoes that help keep balance. If you have the habit of running, you'd better wear shock-absorbing shoes when running, and you should also pay attention to changing shoes regularly.

5, to prevent the patella articular surface from being continuously compressed, and the patella in the knee flexion position is subjected to a large force, which is easy to damage the articular surface. It is necessary to avoid the pressure of continuous squatting on the articular surface of the patella, such as duck step, and keep the knee joint moving in a painless range.
