What is plica syndrome?
Plica syndrome is a condition that causes knee pain. It occurs when the plica, fold in the synovial membrane surrounding the knee joint, becomes inflamed.
What causes plica syndrome?
Plica syndrome is most commonly an overuse injury caused by repetitive movements related to biking, running or other activities. It can also occur as the result of a fall or another traumatic injury.
What are the symptoms of plica syndrome?
The most common symptom of plica syndrome is an achy pain or sensation that grows worse during the offending activity. A clicking or cracking sound in the knee, a locking sensation and the feeling like your knee may give out are other potential symptoms of the condition.
How can plica syndrome affect children?
Plica syndrome can occur in both adults and children, although it appears to be less common in children who are under 10 years old.

Most mild to moderate cases of plica syndrome can be treated with physical therapy
or at-home exercises designed to strengthen the knee and improve flexibility. More severe cases of plica syndrome may require surgery followed by physical therapy for long-term relief of symptoms.
