Synovitis

Synovitis is the inflammation and swelling of the lining of the joint called synovium. In most cases, only one joint is involved and that too for a short period of time. It usually occurs in children between 3 and 10 years of age.

Characteristics of Synovitis

Cause: Although the exact cause of synovitis is not known, it may be caused by a virus or from an allergic reaction to an infection somewhere else in the body.

Symptoms: Sudden hip pain, difficulty walking and standing and walking with a limp.

Treatment: Knee & hip arthroscopy is recommended to partially remove the inflamed synovium. But it is also required to treat the underlying cause of the inflamed synovium so that it does not return.

Swollen Synovium

The synovium or synovial membrane is the soft tissue found in joints like knee and shoulder. It is a thin membrane that surrounds the inner lining of the joint. Its main function is to create synovial fluid, which helps in nourishment and lubrication of the joint.

Characteristics of Swollen Synovium

Cause: Traumatic and repeated knee injuries OR joint diseases like rheumatoid arthritis and gout

Symptoms: Joint pain, tenderness, stiffness and swelling along with redness and warmth over the area

Treatment: Arthroscopy is used for appropriate diagnosis as well as to clean out the inflamed synovium.
