The doctor has confirmed that I am suffering from Plica Syndrome of the knee, and has given me an anti-inflammatory jab for the time being. I am to go back in two weeks time for a final check... humpff.... For now, I am only limited to low-impact exercise :(
What is plica syndrome of the knee?
The plica on the inner side of the knee, called the "medial plica," is the synovial tissue most prone to irritation and injury. When the knee is bent, the plica is exposed to direct injury, and it may also be injured in overuse syndromes. When the plica becomes irritated and inflamed, the condition called "plica syndrome" results."
What is the treatment for plica syndrome?
Symptomatic plica syndrome is best treated by resting the knee joint and anti-inflammatory medications. These measures are usually sufficient to allow the inflammation to settle down. Occasionally, an injection of cortisone in to the knee will be helpful.
If these measures do not alleviate the symptoms, then surgical removal of the plica may be necessary. This surgical procedure is performed using an arthroscope, or a small camera, that is inserted into the knee along with instruments to remove the inflamed tissue. The arthroscopic plica resection has good results assuming the plica is the cause of the symptoms. Often a plica is seen on arthroscopic examination. Unless symptoms are consistent with plica syndrome and the plica looks inflamed and irritated, the plica is usually left alone. Plica resection during arthroscopy is only performed if the plica is thought to be the cause of symptoms.
