The synovial membrane encloses the knee joint and acts to secrete fluid into the joint, which provides nutrition and frictionless movement.
The synovial plica refers to a fold in the synovial membrane, which can produce knee pain when irritated. The synovial plica is found along the inside border of the knee cap. It can produce pain when it becomes inflamed. This may occur following a direct impact to the plica or when it is overstretched.
This may occur following a direct impact to the plica or when it is overstretched.
Physiotherapy would aim to correct biomechanics of the knee to decrease irritation of the plica, in some cases surgical intervention is required. Treatment wise, however, it has been shown in literature, that surgery ensures longer long-term therapeutic effect maintenance than conservative treatment only (Luo et al., 2016).
