I was training a young horse that kept trying to push me into the fencepost. My knee got pretty banged up. Now, I have a large knot on the outside of my leg just below the knee. It especially hurts when I put weight on my leg. Could it be broken?

The lower leg is made up of two bones: the tibia (main bone) and the fibula (smaller bone along the outside). The place where these two bones meet is called the tibiofibular joint. There are strong ligaments that hold this joint together. It’s possible that you have a fracture. It could also be a tear of the soft tissues around this joint. An X-ray is needed to know for sure. The doctor will also examine your leg and test the tibiofibular joint as well as the knee joint. It’s easy to confuse a knee joint injury for a tibiofibular joint injury.
