A groin strain is a partial tear of the small fibers of the adductor muscles. The adductorsare a group of three muscles located on the inner aspect of the thigh. They start in the groin area and run down the inner thigh attaching to the inner side of the knee. Athletes competing in sports that require running, changes in direction, repetitive kicking and physical contact such as football, GAA, rugby and hockey, are at a relatively higher risk of experiencing episodes of groin injury.
