Knee Cap Problems
Pain in the front part of the knee is caused by a kneecap problem called Patella Femoral Pain
Syndrome (PFPS).
What is Patella Femoral Pain Syndrome?
Patella Femoral Pain Syndrome (PFPS) is a condition of the kneecap characterized by a rough or
soft spot on its cartilage surface. In the past, it has been called chondromalacia patella,
runner's knee of dashboard knee.
What are the symptoms?
It causes pain, giving away, stiffness and a feeling of catching or grinding. Going up and down
stairs is a bit difficult, and sitting with your knees bent or squatting is very uncomfortable.
It makes the knee "give out," grind, or pop loudly.
Who gets it?
Almost everyone has PFPS, but only about 10 percent have pain or disability because of it - a
fact not clearly understood by the medical profession.
Over-activity, excess weight and injury sometime initiate the symptoms. This condition is often
seen in adolescents, manual laborers and athletes.
How is it diagnoses?
Cartilage contains no calcium and, as a result, cannot be seen by ordinary x-rays. A patient's
history and physical examination suggest the diagnosis. If there is any doubt, we will suggest
arthroscopy to look behind the kneecap and check to see that there is no abnormality.
Arthroscopy, however, is usually not indicated for PFPS.
How long does PFPS last?
It may last several months, but fortunately, is usually a self limited problem. If you are born
with an abnormal kneecap, it may last indefinitely. You may even need an operation to correct it,
though this is unusual.
What is the treatment?
Small doses of anti-inflammatory medicines can often decrease swelling, stiffness and pain.
Other treatments may include injections, ice, rest, and physical therapy. Taping and a brace
to stabilize the kneecap also can be helpful.
Now for the good news!
The good news is that although PFPS can be uncomfortable, usually it is only a short term
nuisance and inconvenience. It also generally does not lead to arthritis or any other joint
condition.
