Synovial Plica Irritation

The synovial plica is a synovial fold found along the inside of the knee cap causing pain and discomfort. It may sometimes be confused with patellofemoral pain syndrome.

Synovial plica symptoms

Symptoms of a synovial plica include a sharp pain at the front inside edge of the kneecap. The pain may also be towards the back of the patella. The athlete may feel a sharp pain when squatting. A synovial plica may sometimes feel like a thickened band under the inside of the kneecap.

What is a synovial plica?

The knee joint is lubricated with a substance called synovial fluid. This fluid is surrounded by and produced by a sheath called the synovial sheath. The synovial plica is a synovial fold found along the inside border of the knee cap. The synovial sheath may also become more widely inflamed. This is known as knee synovitis.

Synovial plica prevention

A synovial or patella plica should be considered the main cause of pain only when the patient has failed to respond to treatment of patello femoral pain syndrome. A surgeon may perform an arthroscopy to look into the joint, identify a plica and remove it.
