What are the signs and symptoms of patellofemoral syndrome?

Generalized pain around the kneecap is the most common symptom of patellofemoral syndrome:

The patient may have a history of a dull, aching pain in the knee, not necessarily in one specific area.

If the pain is in front of the knee below the kneecap, it is probably caused by tendon inflammation called infrapatellar tendonitis or "jumper's knee".

Running, going down stairs, squatting, or sitting for a long time with knees bent usually increases pain.

Although full range of motion is usually possible, flexing the knee completely is painful.

Crepitus (a crackling noise under the patella) may occur during knee movement.

A slight swelling may exist

Symptoms may be present in one or both knees.
