Pigmented Villonodular Synovitis
Pigmented Villonodular Synovitis Causes
What triggers or causes the disease remains unknown to physicians. The disease is also not genetic, and appears to affect anyone of any age.
Pigmented Villonodular Synovitis Definition
The disorder pigmented villonodular synovitis (PVNS) results when the lining of our joints become swollen. Commonly affecting the hip and knee, the lining produces extra fluid that induces swelling and makes motion very painful. PVNS may be localized or diffused. Diffused PVNS usually affects larger joints like the knees, while the localized type damages smaller joints like hands or feet.
Pigmented Villonodular Synovitis Diagnosis
Because this disorder resembles arthritis or other joint conditions, doctors require patients to undergo physical exams, X-rays and magnetic resonance imaging (MRI). The fluid in the joints is also tested.
Pigmented Villonodular Synovitis Symptoms and Signs
With PVNS, the joint suddenly swells and becomes painful. As the disease progresses, motion becomes limited while the pain intensifies. Localized PVNS usually is painless at first building on to the common signs of the disease. Diffuse PVNS may be confused with rheumatoid arthritis. Swelling usually feels warm.
Pigmented Villonodular Synovitis Treatment
Treating the disorder involves two processes. The first is the removal of the joint's lining through traditional surgery. To prevent the recurrence of the pain, radiation therapy is conducted. Patients may also ease the pain and swelling by resting the affected joint and staying off their feet. Anti-inflammatory medicines could also reduce the pain and swelling. In extreme cases, the joint should be totally replaced.
