What is Synovial Plica?
Synovial plica, sometimes referred to as patella plica, is an injury to the fold in the sheath that surrounds and produces the synovial fluid that lubricates the knee. This injury results in irritation or inflammation of the fold, which is found along the inside border of the knee cap.
If you have synovial plica, you will feel variable sharp pain in the front, inside edge, or back of the kneecap. You may also experience sharp pain when you squat, and some people can feel a thickened band (the plica) under the inside of their kneecap.
Treatment of Synovial Plica
A surgeon may perform an arthroscopy to inspect the knee joint to determine the presence of a synovial plica. Treatment focuses on reducing the inflammation, which typically includes nonsteroidal anti-inflammatory medication. Rehabilitative exercises can begin once the inflammation and pain are reduced. If these measures are not successful, surgery to remove the plica may be necessary.
