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 kneecap. The synovial sheath may also become more widely inflamed. This is known as knee synovitis.[the_ad id=”41081″]
Preventing Synovial plica
A synovial or patella plica should be considered the main cause of pain only when the patient has failed to respond to treatment of patellofemoral pain syndrome. A surgeon may perform an arthroscopy to look into the joint, identify a plica and remove it.
