Pigmented Villonodular Synovitis (PVNS)

What is Pigmented Villonodular Synovitis (PVNS)?

Pigmented Villonodular Synovitis (PVNS) is a joint disease of the synovium, or joint lining. It is characterized by inflammation and overgrowth of the synovium and it typically affects the hip or ankle. The overgrowth and inflammation harms the joint, leading to early joint damage. Typically patients complain of pain and restricted movement.

Nodule of diseased PVNS which was removed during hip arthroscopy

The above nodule of diseased PVNS was removed during a hip arthroscopy procedure.

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.

Surgical Treatment Options for Video of Pigmented Villonodular Synovitis (PVNS)

Surgery is typically recommended as a treatment for PVNS, with the type of surgery dictated by the extent of damage to the joint. In cases where significant degeneration has occurred and the damage is more advanced, a joint replacement is recommendable in the hip, while a fusion is the recommendation for the ankle. In cases of minimal joint damage, an arthroscopic procedure may be performed to remove as much of the diseased synovium as possible. Even with surgery, the PVNS may recur and require additional treatments including repeat surgery or radiation therapy.
