Synovial osteochondromatosis

Synovial Osteochondromatosis

Synovial osteochondromatosis (pronunciation: sih-NO-vee-ul os-tee-o-kon-droh-muh-TOE-sis) is a rare, benign condition characterized by the formation of cartilage nodules in the synovium, the thin layer of tissue that lines the joints and tendon sheaths.

Etymology

The term "synovial" is derived from the Greek word "synovia," which means "like an egg," referring to the viscous fluid found in the joints. "Osteochondromatosis" comes from three Greek words: "osteon" (bone), "chondros" (cartilage), and "osis" (condition).

Symptoms

Patients with synovial osteochondromatosis often experience joint pain, swelling, and limited range of motion. The knee is the most commonly affected joint, but the condition can occur in any joint.

Causes

The exact cause of synovial osteochondromatosis is unknown. It is thought to occur when the synovium undergoes metaplasia, a process in which one mature tissue type transforms into a different mature tissue type.

Diagnosis

Diagnosis of synovial osteochondromatosis typically involves a physical examination, medical history, and imaging tests such as X-rays, MRI, or CT scan. In some cases, a biopsy of the synovium may be necessary.

Treatment

Treatment options for synovial osteochondromatosis include physiotherapy, pain management, and in severe cases, surgery to remove the nodules and affected synovium.
