What causes pain below the right knee?

Pain below the right knee is generally associated with factors such as trauma, gout, osteoarthritis, chondromalacia patellae, and rheumatoid arthritis. Patients are advised to follow medical guidance for symptomatic treatment. Specific analyses are as follows:

1. Trauma

If the area below the right knee suffers external impact, causing sprain or contusion of muscles and soft tissues on the lower right side of the knee, pain may occur. Patients should reduce knee joint activity and ensure adequate rest. In cases of significant pain, medications such as ibuprofen sustained-release capsules or Huoxue Zhitong capsules may be taken orally according to medical advice.

2. Gout

Abnormal purine metabolism in the body leads to elevated uric acid levels. When uric acid exceeds its saturation concentration, uric acid crystals can form and deposit beneath the knee joint, triggering gout. These crystals release inflammatory factors that irritate surrounding muscles and nerves, resulting in pain below the right knee. Under medical guidance, patients may take medications such as febuxostat tablets or allopurinol tablets for treatment.

3. Osteoarthritis

When knee osteoarthritis flares up, inflammatory factors can cause local tissue congestion, edema, and exudation, leading to pain below the right knee. Patients may take celecoxib capsules or diclofenac sodium sustained-release tablets under medical supervision.

4. Chondromalacia Patellae

In patients with chondromalacia patellae, cartilage beneath the kneecap becomes worn, which may lead to the aforementioned symptoms. Treatment may include taking aspirin tablets or loxoprofen sodium tablets as directed by a physician.

5. Rheumatoid Arthritis

Rheumatoid arthritis is a common rheumatic disease. During flare-ups, it may affect joints throughout the body and is often accompanied by increased uric acid deposition. It can invade joints and also affect surrounding soft tissues. Under medical guidance, patients may take prednisone acetate tablets or cyclosporine soft capsules for treatment.

If patients experience discomfort symptoms, they are advised to seek timely medical evaluation at a hospital to avoid delays in diagnosis and treatment.
