Chorionodular synovitis of the knee

Chorionodular synovitis of the knee is a chronic inflammatory disease of the synovium, which is mainly manifested by swelling, pain and limited movement of the knee joint. Its cause may be related to genetics, environmental factors, physiological factors, trauma and pathological changes. Treatment methods include drug therapy, surgical treatment and rehabilitation exercises.

1. Genetic factors

Some patients may have genetic susceptibility, and those with a family history of similar diseases have a higher risk of developing the disease. Genetic factors may increase the sensitivity of synovial tissue to inflammatory responses, thereby inducing the disease.

2. Environmental factors

Long-term exposure to damp or cold environments or overuse of the knee joint may induce synovitis. For example, people who engage in heavy physical labor or excessive exercise put greater pressure on the knee joint, which can easily lead to synovial injury and inflammation.

3. Physiological factors

Ageing, obesity or degenerative knee disease may increase the risk of disease. With age, the repair ability of the synovial membrane in the joint decreases, and obesity will increase the burden on the knee joint and accelerate synovial damage.

4. Trauma

Knee joint trauma, such as sprain, impact or surgical trauma, may directly damage the synovial tissue and trigger an inflammatory response. Failure to promptly treat or improper rehabilitation after trauma may also lead to chronic synovitis.

5. Pathological changes

Synovitis may be caused by other diseases, such as rheumatoid arthritis, gout, or infectious diseases. These diseases can cause pathological changes in the synovial tissue and form chorionodular lesions.

Treatment

1. Drug treatment

Nonsteroidal anti-inflammatory drugs such as ibuprofen and diclofenac can relieve pain and inflammation.

Corticosteroids such as prednisone can be used to control acute inflammation.

Immunosuppressants such as methotrexate are used for patients with more severe disease or recurrent attacks.

2. Surgical treatment

Arthroscopic synovectomy: minimally invasive surgery to remove diseased synovial tissue.

Open synovectomy: suitable for patients with larger lesions.

Arthroplasty: Consider when synovitis causes severe joint destruction.

3. Rehabilitation exercises

Low-intensity aerobic exercises such as swimming and cycling can strengthen the muscles around the knee joint and reduce the burden on the joints.

Knee flexion and extension exercises: Perform flexion and extension exercises for 10-15 minutes every day to help restore joint mobility.

Physical therapy: such as hot compress and ultrasonic therapy, can promote local blood circulation and relieve symptoms.

The treatment of chorionodular synovitis of the knee requires a personalized plan based on the cause and severity of the disease. Early diagnosis and intervention are key. Patients should avoid overuse of the knee joint, keep warm, control their weight, and undergo standardized treatment and rehabilitation exercises under the guidance of a doctor. Regular review and adjustment of treatment plans can help improve prognosis and quality of life.
