The pathogenic factors are complicated. More studies agree with the viewpoint of sports traumatology, and think that patients have a history of knee joint hyperactivity and semi-squat torsion injury, as well as abnormal patella position, such as oblique position and high patella. Women love to wear high-heeled shoes. Wearing them for a long time will cause abnormal pressure on knee cartilage, leading to ischemic changes, abnormal cartilage metabolism, cartilage softening, erosion, peeling and other degeneration. Another study shows that the number of female patients increases sharply after entering the age of 40, which may be related to the decrease of estrogen level in the body. Traditional Chinese medicine believes that this disease is patellar strain, which belongs to "arthralgia syndrome" and is related to qi stagnation and blood stasis and meridian obstruction.

Daily concern

1, move joints before exercise. Fully moving the joint before exercise can stimulate all parts of the articular surface of the patella, and the nutrients of synovial fluid can penetrate into the cartilage tissue evenly, thus enhancing the lubrication of the joint.

2. Avoid strenuous exercise and avoid continuous squatting and 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.
