What is a pigmented villonodular synovitis?

pigmented villonodular synovitis is a condition that affects the synovial membrane that surrounds the joints. This condition is most often observed in the knee, although it can occur in joints such as hips and hands. The cause is unknown; There is no genetic component, and there are no obvious risk factors that could provide guides, why some people develop pigmented villonodular synovitis. This leads to inflammation and swelling as the fluid is being built. The joint can become stiff and difficult to move and the patient often experiences joint pain. Swelling may have a very fast onset that can complicate a diagnosis because it may look like a result of voltage or sprains.

There are several diagnostic tools that can be used to identify pigmented villonodular synovitis. A fluid sample can be analyzed inside the joint and the joint can also be executed in a medical imaging study such as MRI. Palpation of the joint can also provide guides as it can be pSabbath, which suggests that there are tumors on the joint or around it.

In addition to limiting the extent of joint movement and causing pain, pigmented villonodular synovitis can also eat into the surrounding bone, causing lesions. For this reason, it is necessary to treat the condition, preferably before lesions begin to form. Treatment includes surgery to remove part of the synovial membrane and overgrow and restore the joint to normal. However, recurrence after surgery is very high, almost 50%. For this reason, some doctors recommend using radiation therapy on the joint to solve cells that grow too fast, from the hope of preventing excessive growth.

This condition occurs most often in men between 20 and 45. The men in this age range are also threatened by joint injuries such as sprains that can complicate the diagnosis of pigmented villonodular synovitis because the doctor does not have toBut it can be recognized immediately, so it may take several months or even years to realize what is happening. If the pigmented villonodular synovitis are returned or caused by serious damage, the surgeon can recommend the location of the artificial joint. The replacement of the joint is a more invasive and more complicated procedure, and therefore it is only recommended when it seems to be a good choice for the patient.
