Has anyone hear of Patellor Femoral Syndrome? It's where your inside quad is weaker than your outside and many enduro riders have and don't even know it. It's a result of standing up and or placing your weight on the outside of your footpegs, this results in your outside quad getting stronger while weakening your inside. This leads to the outside quad pulling your knee cap out of it's groove alignment and inflaming the cartlidge. There are many special excercise to increase strength but you must isolate the quad. Does anyone know of a good knee brace designed to secure the knee cap and still offer good protection against injuries?
