Runner’s Knee – Common Causes and Prevention
Runner’s Knee Definition
Runner’s knee is used as a catch-all term for pain and discomfort located in the front or outside of the knee. Common conditions linked to runners knee are:
- Patello-femoral Syndrome
- Illiotibial Band Syndrome
- Patellar Tendonitis
All of the conditions above can be linked to muscular dysfunction distorting the true mechanical position of the knee joint. The potential muscular imbalances, may lead to the misalignment of the patella (kneecap) with the end of the femur (thigh bone). A misalignment of the knee cap may place excessive stress on many of the connective tissues responsible for knee function. A misalignment may also create unnecessary friction between the bones of the knee. These stresses may surface with strength or endurance activities and develop over a period of time.
Prevention of Runner’s Knee
Retraining the muscles involved with the tracking of the knee cap will allow for irritated connective tissues and damaged bone to heal. Muscles are solely responsible for the position and overall function of a joint. There is a sequence of exercises that will begin to establish an equal relationship between the muscles of your knee that will reinforce the ideal joint position. Performing these exercises before activity will help to ensure proper alignment during exercise. Using these exercises after activity will address any uneven muscular fatigue.
Always consult a physician before attempting any exercise program
