Stretching exercises are good for prevention of runner's knee, particularly those exercises designed for the quadriceps muscles. A moderate training program should avoid stress on the knee. Excessive distance, speed, and hills should be avoided. Orthotics, or arch supports, may help to reduce pronation of the foot.
Long-term effects of runner's knee are rare. If overuse continues and symptoms are ignored, arthritis is a possibility.
Runner's knee is not contagious, and poses no risk to others.
