are one of the most common joint injuries runners experience. The injury can occur when one rolls over a rock, lands off a curb, or steps in a small hole or crack in the road. Usually the sprain is only mild, but on occasion it may seriously injure the ligaments or tendons surrounding the ankle joint. Management of this injury relies on early and accurate diagnosis, as well as an aggressive rehabilitation program directed toward reducing acute symptoms, maintaining ankle stability, and returning the runner to pre-injury functional level. Treatment includes resting the ankle and applying ice to reduce swelling. Compressive bandages also may be used to immobilize and support the injury. More serious ankle sprains, particularly in competitive athletes, may require surgery to repair to tighten the ligaments.
