Villonodular Synovitis (Pigmented), Knee: Causes, Symptoms, Diagnosis, and Treatment

Villonodular synovitis (pigmented), also known as PVNS, is a rare joint condition that occurs in the lining of the joints, tendons, and bursae. This condition is characterized by the overgrowth of the synovial tissue, which lines the joints and produces fluid that lubricates and nourishes the joint. PVNS is most commonly found in the knee joint, but it can also affect other joints in the body.

Causes of Villonodular Synovitis (Pigmented), Knee

The exact cause of PVNS is unknown. However, some researchers believe that it may be caused by a genetic mutation or a dysfunction in the immune system. The condition may also be related to previous joint injuries or trauma.

Symptoms of Villonodular Synovitis (Pigmented), Knee

Common symptoms of PVNS include pain, swelling, stiffness, and reduced range of motion in the affected joint. The joint may also feel warm to the touch, and there may be a clicking or popping sound when the joint is moved.

Diagnosis of Villonodular Synovitis (Pigmented), Knee

A doctor will typically diagnose PVNS based on a physical exam, medical history, and imaging tests such as X-rays, MRIs, or ultrasounds. A biopsy may also be taken to confirm the diagnosis.

Treatment of Villonodular Synovitis (Pigmented), Knee

There are several treatment options available for PVNS. Non-surgical treatments may include pain management medication, physical therapy, and the use of braces or crutches to support the affected joint. In some cases, surgical intervention may be necessary to remove the overgrown synovial tissue and repair any damage caused by the condition.

  1. Non-Surgical Treatment
    • Pain management medication
    • Physical therapy
    • Use of braces or crutches to support the affected joint
  2. Surgical Treatment
