I saw this article on a common knee injury known as patellofemoral syndrome. http://www.sportsinjurybulletin.com/archive/1044-cyclists-knee-injuries.htm It is a great article on the mechanics of the this common problem in cyclists and many other athletes. This syndrome rarely becomes a surgical event when managed properly. Icing, quad and hip flexor stretching, combined with ART (Active Release Techinque) can be a great remedy for this type of pain. When you add to these treatment strategies an anti-inflammatory diet you can really speed up the healing process. Foods that are low in sugar, high in anti-oxidants, and high in Omega 3 fats can be essential in decreasing your body’s inflammatory response. The next time your knee is swelling and painful follow these steps and watch how quickly you will be back on the road.
