Patellofemoral Pain Syndrome
What is patellofemoral pain syndrome?
Patellofemoral pain syndrome is pain in the front of the knee. It frequently occurs in teenagers, manual laborers, and athletes. It sometimes is caused by wearing down, roughening, or softening of the cartilage under the kneecap.
What causes patellofemoral pain syndrome?
Patellofemoral pain syndrome may be caused by overuse, injury, excess weight, a kneecap that is not properly aligned (patellar tracking disorder), or changes under the kneecap.
What are the symptoms?
The main symptom of patellofemoral pain syndrome is knee pain, especially when you are sitting with bent knees, squatting, jumping, or using the stairs (especially going down stairs). You may also experience occasional knee buckling, in which the knee suddenly and unexpectedly gives way and does not support your body weight. It is also common to have a catching, popping, or grinding sensation when you are walking or when you are moving your knee.
How is patellofemoral pain syndrome diagnosed?
Your doctor will conduct a medical history and physical exam to determine the cause of your pain. In some cases, imaging tests including X-rays or magnetic resonance imaging (MRI) may be done. These tests allow a doctor to view the tissues inside your knee to rule out damage to the structure of the knee and the tissues connected to it.
How is it treated?
Patellofemoral pain syndrome can be relieved by avoiding activities that make symptoms worse.
