Plica is nothing but pleats of synovial tissue normally found in all knees. There are four plica (synovial folds) normally present in the knee joint.
Most often than not only the medial plica may become symptomatic. The medial plica attaches to the lower end of the patella (knee cap) and runs sideways to attach to the lower end of the thigh bone at the inner side of the knee joint.
» Causes :
The medial plica becomes symptomatic when it is irritated by certain movements of the knee.
The predisposing factors are
- Teenage athletes
- Blunt or twisting knee injury
- Repetitive knee flexion-extension e.g. rowing, swimming, cycling
» Clinical Features :
Pain on the inner side of the patella
Snapping sensation on knee flexion
» Diagnosis :
» Management :
Conservative Management :
Surgical Management :
- Rest, ice
- Anti-inflammatory medications
- Local cortisone injection
This is indicated when conservative measures fail and there is intolerable pain and discomfort.
The symptomatic plica is excised under the guidance of an arthroscope.
