What is Pvns in the knee?
Pigmented villonodular synovitis ( PVNS ) is a condition that causes the synovium—the thin layer of tissue that lines the joints and tendons—to thicken and overgrow. The mass or tumor that results from this overgrowth is not cancerous and does not spread (metastasize) to other areas of the body.
How common is Pvns?
PVNS is a rare condition. It affects only about 2 out of every 1 million people .
Is Pvns a disability?

Is Pvns an autoimmune disease?
Pigmented villonodular synovitis is a rare disease of unknown etiology mostly affecting the knee and foot. Until now an association with autoimmune diseases has not been reported.
Is Pvns malignant?
Malignant PVNS is an extremely rare condition but established concept involving a malignant form of GCTTS or PVNS . Enzinger and Weiss proposed the definition of the condition as a malignant lesion occurring with concomitant or previously documented conventional PVNS at the same site .
How is Pvns diagnosed?
Pigmented villonodular synovitis ( PVNS ) is diagnosed via physician examination, imaging studies, and sometimes surgical procedures. Imaging studies commonly used include: X-ray , MRI , and CT scan . MRI findings are diagnostic in more than 95% of patients.
Is Pvns hereditary?
PVNS is idiopathic, i.e. it occurs without any specific cause. There is no genetic or hereditary association, and it is not related to activity levels.
What is synovectomy surgery?
Synovectomy surgery is done to remove inflamed joint tissue (synovium) that is causing unacceptable pain or is limiting your ability to function or your range of motion. Ligaments and other structures may be moved aside to access and remove the inflamed joint lining. The procedure may be done using arthroscopy.
What is Pvns in medical terms?
Pigmented villonodular synovitis , or PVNS , is a benign tumor that occurs in the joints themselves. It’s a progressive disease that affects the joint lining, and — in severe cases — can cause joint destruction. It most often affects the knee, although it can affect other joints as well.

How long does it take to recover from synovectomy?
The procedure was well tolerated in 93% of cases. The mean time needed to achieve a stable improvement was 3.2 weeks for pain, 4.7 weeks for swelling and 3.6 weeks for range of motion.
What is the treatment for synovitis?
Treatment for synovitis usually consists of rest and anti-inflammatory medications. Medications may include oral drugs known as DMARDs (disease-modifying antirheumatic drugs) and, in some cases, steroid injections .
What causes synovial Osteochondromatosis?
The exact underlying cause of synovial chondromatosis is unknown. Some research suggests that trauma may play a role in its development because the condition primarily occurs in weight-bearing joints. Infection has also been considered as a contributing factor. The condition is not inherited .
