How can synovitis be diagnosed?

Synovitis can be diagnosed through clinical symptoms and imaging tests such as X-rays, magnetic resonance imaging (MRI), and laboratory tests such as blood tests. If symptoms such as joint swelling and pain occur, you should see a doctor immediately, who will provide a comprehensive examination to confirm the diagnosis and develop a treatment plan.

1) Clinical symptom assessment

Typical symptoms of synovitis include joint swelling, soreness, and limited mobility. In severe cases, effusion or joint deformity may occur. Doctors usually make a preliminary diagnosis by palpation and observing the patient's limited mobility. If obvious abnormalities are found, such as local redness, swelling, heat, and pain in the joint, synovitis may be present.

2) Imaging examination

Imaging examination is an important means to diagnose synovitis.

-X-rays: can be used to exclude structural joint lesions such as osteoarthritis, but have limited visualization of synovial soft tissue.

-Ultrasound examination: It can visually observe the thickening and effusion of the synovium and is a simple tool for diagnosing synovitis.

-Magnetic resonance imaging (MRI): MRI has a high resolution and can clearly show synovial thickening, inflammatory changes and involvement of surrounding soft tissues. It is the "gold standard" for diagnosing synovitis.

3) Laboratory tests

Synovitis may be caused by immune or infectious factors. Blood tests can help determine the cause and degree of inflammation.

- Blood test: to assess the number of white blood cells and detect infection.

-C-reactive protein (CRP) and rheumatoid factor: Helps determine if there is an autoimmune disease such as rheumatoid arthritis.

-Synovial effusion test: The effusion in the joint cavity is extracted for analysis to determine whether it is infectious synovitis and the type of pathogen.

After a clear diagnosis, treatment can be divided into drug therapy, physical therapy and surgical treatment. In the early stage of synovitis, nonsteroidal anti-inflammatory drugs (such as ibuprofen) and glucocorticoids (such as methylprednisolone) are usually selected to reduce inflammation. If the effusion is severe, joint puncture and fluid extraction may be required to relieve pressure. Patients with chronic or severe synovitis may require arthroscopic surgery to remove the diseased synovium. Physical therapy such as hot compresses and ultrasound therapy can promote recovery.

When synovitis is suspected, the above-mentioned examinations should be used to confirm the diagnosis and take appropriate intervention measures as soon as possible. Timely diagnosis and treatment can reduce the risk of complications and joint function deterioration. If you feel unwell, you should not delay and seek medical attention in time.
