What Are Signs and Symptoms of Synovitis in the Knee?

Signs and symptoms of knee synovitis include more frequent bleeding in the affected joint, lack of pain and no motion loss until an active bleeding occurs, and a soft, swollen knee joint despite treatment, reports Hemophilia of Georgia. Synovitis usually occurs due to recurrent joint bleeding without proper treatment.

Synovitis is a condition involving inflammation of the synovial membrane, explains Hemophilia of Georgia. The synovial membrane exists in the area of the body lining the inner part of joint capsules in the knees, ankles, feet, hands and shoulders. The membrane also lines the joint capsules in the elbows and wrists. Because of frequent joint bleeding, the membrane becomes thicker and produces more blood vessels, leading to further bleeding into the affected joint.

Prevention of synovitis involves regular exercise, prompt treatment of joint bleeding and regular checkups with a joint doctor, notes Hemophilia of Georgia. If patients experience synovitis symptoms or suffer joint bleeding at least three times monthly, doctors may recommend prophylactic treatment to prevent bleeding and promote the restoration of the synovial membrane.

Doctors sometimes prescribe oral steroids to decrease inflammation, but these medications are advisable for only one to two weeks as they may lead to other health problems, states Hemophilia of Georgia. Physical therapy provides pain relief, prevents loss of movement, and increases joint and muscle strength. Arthroscopic synovectomy and radionuclide synovectomy are other potential treatments.
