Patellofemoral Syndrome

This syndrome is caused by changes in the undersurface of the knee cap (patella). The changes vary from minor inflammation to major changes such as breakdown of the cartilage on the undersurface of the patella. The major changes can be seen with an arthroscope (a small, pencil sized telescope). These changes can result from various factors. Patellofemoral SyndromeThese factors may arise from abnormal tracking (movement or malalignment) of the patella. Normally the Patella is in its normal groove located between the condyles (grooved end) of the femur (thigh bone). Abnormal movement leads to increased pressure in the patellofemoral joint. This leads to swelling in the cartilage, inflammation and pain.

Symptoms

The patient with this syndrome usually has an ache in the knee. It is often aggravated by:

  • Prolonged sitting
  • Squatting
  • Climbing stairs
  • Running down hill
  • Other exercising that stresses the knee.
    Other findings may include the knee giving way, swelling, and or locking

Treatment and Home Care Instructions

  • The treatment will depend on the cause of the problem. Sometimes the solution is as simple as cutting down on activities. Giving your joint a rest with the use of crutches and braces can also help. This is generally followed by strengthening exercises
  • Following exercise use an ice pack for twenty to thirty minutes three to four times per day. Use a towel between your ice pack and the skin
  • Reduction of inflammation with anti-inflammatories may be helpful. Only take over-thecounter or prescription medicines for pain, discomfort, or fever as directed by your caregiver
  • Taping the knee or using a neoprene sleeve with a patellar cutout to provide better tracking of the patella may give relief
  • Muscle (quadriceps) strengthening exercises are helpful. Follow your caregiver’s advice
  • Muscle stretching prior to exercise may be helpful
  • Soft tissue therapy using ultrasound, and diathermy may be helpful
  • If conservative therapy is not effective, surgery may provide relief. During arthroscopy, your caregiver may discover a rough surface beneath your kneecap. If this happens, your caregiver may smooth this out by shaving the surface

Recovery

Recovery from a patellar problem depends on the type of problem in your knee and on the treatment required. If conservative treatment works the recovery period may be as little as three to four weeks. If more aggressive therapy such as surgery is required, the recovery period may be several months. Your caregiver will discuss this with you.
