If you have pain on the outside of your knee, you’re in a club of your own. When I meet people who have pain here, I often find (there are exceptions) that rotation internally of both tibia and femur results in a decrease in their pain (the opposite of what to do if pain is on the inside). Upon further questioning, many of these people are or were runners or cyclists. My hypothesis at the moment is that a tight Iliotibial band (ITB) is the culprit (I’m sure there are exceptions). The ITB seems to be placing some type of rotational force on the knee that is causing pain. I assume it’s rotational in nature because when I rotate the femur and tibia internally, the pain is reduced or goes away.
