Knee Pain When Bending And Straightening
What Causes PFP Syndrome? – Patellofemoral (pronounced: peh-tel-oh-FEM-er-ul) pain syndrome is an overuse disorder, These happen when someone does the same movements that stress the knee over and over again. In PFP syndrome, repeated bending and straightening the knee stresses the kneecap.

  1. It’s most common in athletes.
  2. Some people with PFP syndrome have a kneecap that is out of line with the thighbone (femur).
  3. The kneecap can get out of line, or wiggle as it moves along the thighbone, because of muscle weakness, trauma, or another problem.
  4. If this happens, the kneecap doesn’t glide smoothly over the thighbone when the knee bends and straightens.

The kneecap gets injured and this causes the pain of PFP syndrome.
