Plica Syndrome is difficult to diagnose. The orthopedic physician reviews the medical history of the patient and thoroughly examines the knee. He tries to access the extent of damage by the injury and determine the cause of the injury. The physician will look for a thickened piece of irritated tissue on the knee. He will also assess the strength and mobility in the knee. The physician may ask certain questions related to the routine activities of the patient. He also recommends imaging tests such as x-ray or MRI to find the source of pain.


Often Plica Syndrome is cured without surgery; however if the problem persists the patient has to undergo surgery. The patient is suggested to limit the physical activities to reduce the inflammation. The doctor may also prescribe some anti-inflammatory medicines to reduce swelling. Ice packs and massages can also help. In case the symptoms persist, the patient may have to undergo surgery. There is no harm in removing plica as your body can remain without it. The surgery does not involve any complications and side effects. The recovery time ranges from four to six weeks.

During the recovery period, a physiotherapist can help patients recover the lost strength and mobility. Regular stretching and strengthening exercises benefit the knee. The patient should allow complete recovery before starting any physical activity or sports.
