Patellofemoral Pain Syndrome (Runner's Knee)
Runner's knee, also known as patellofemoral pain syndrome, is a condition characterized by dull pain around the front of the knee (patella), where it connects with the lower end of the thigh bone (femur).
Runner's knee may be caused by a structural defect, or a certain way of walking or running. Other causes may include the following:
- a kneecap that is located too high in the knee joint
- weak thigh muscles
- tight hamstrings
- tight Achilles tendons
- poor foot support
- walking or running with the feet rolling in, while the thigh muscles pull the kneecap outward
- excessive training or overuse
- injury
The following are the most common symptoms of runner's knee. However, each individual may experience symptoms differently. Symptoms may include:
- pain in and around the kneecap that may be felt with activity, or even after prolonged sitting with the knees bent, occasionally resulting in weakness or feelings of instability
- rubbing, grinding, or clicking sound of the kneecap that can be heard at times when the knee is bent and straightened
- kneecap is tender to the touch
The symptoms of runner's knee may resemble other conditions and medical problems. Always consult your physician for a diagnosis.
Diagnosis of a runner's usually is confirmed with a complete medical history and a physical examination.
Specific treatment for runner's knee will be determined by your physician based on:
- your age, overall health, and medical history
- extent of the injury
- your tolerance for specific medications, procedures, surgeries, or therapies
- expectations for the course of the injury
- your opinion or preference
The best course of treatment for runner's knee is to stop running until running can resume without pain. Other treatment may include:
- cold packs, compression, and elevation
- medications such as ibuprofen
- stretch exercises
- strengthening exercises
- arch support in shoes
