What causes knee pain?

Under normal circumstances, knee pain may be caused by growing pains, joint strain, ligament injury, synovitis, or rheumatoid arthritis. Treatment methods such as general management and medication can be used under the guidance of a doctor. Specific analyses are as follows:

1. Growing Pains

Commonly seen in children, growing pains occur when rapid bone growth is not synchronized with the surrounding muscles, ligaments, and other soft tissues, leading to traction-induced pain and subsequent knee pain. In daily life, intense physical activity should be moderately reduced.

2. Joint Strain

Prolonged weight-bearing or improper use of joints may lead to excessive wear and tear of the muscles, ligaments, cartilage, and other tissues around the knee joint, causing pain. Symptoms may be relieved by alternating cold and heat compresses.

3. Ligament Injury

Exercise, trauma, and other factors can cause ligament injuries. Such injuries affect the ligaments of the knee joint, resulting in pain. Swelling and bruising around the joint may accompany the condition. Treatment may include medications such as loxoprofen sodium tablets, Duyiwei capsules, and Sanqi injury medicine tablets, taken as directed by a physician.

4. Synovitis

Synovitis is often caused by trauma, infection, or rheumatic diseases. It may lead to urate deposition within the knee joint, irritating the synovial membrane and causing the aforementioned symptoms. Systemic fever may also occur. Patients should take medications such as celecoxib capsules, synovitis granules, and etoricoxib tablets as prescribed by their doctor.

5. Rheumatoid Arthritis

Genetic factors, infections, and immune system disorders may all contribute to this condition. Rheumatoid arthritis can damage the articular cartilage of the knee, narrowing the joint space and causing knee pain. Symptoms such as joint swelling and stiffness may also be present. Medications such as tripterygium glycosides tablets, prednisone acetate tablets, and acetaminophen tablets should be used under medical supervision.

To maintain knee joint health, it is important to engage in moderate exercise, avoid prolonged weight-bearing activities and intense physical exertion, keep the joints warm, and prevent exposure to cold, thereby reducing stress on the knee joints.
