|This medial plica is being nipped between patella and femur during joint movement. Above the knee the suprapatellar plica may become nipped between the femur and the quadriceps tendon.||Such trauma can cause the tissue fold to become inflamed and thickened, and then nippling (catching) can occur more often.||Discomfort is typically felt on the inner aspect of the knee. A medial plica may be palpable as a tender cord-like structure on the lower inner quadrant of the knee.|
Treatment of Plica syndrome
Treatment may includes anti-inflammatory medication, local steroid injection, physiotherapy to strengthen the quadriceps and hamstrings mucles and arthroscopic surgery to remove the structure entirely.
