Ankle sprains are the most common sports-related injury. After either landing a jump or "twisting" the ankle, the usual presentation is pain on palpation and swelling over the anterolateral ankle where the most commonly injured ligament is the anterior talofibular ligament. Depending on the type of sprain, pain, swelling, and ecchymosis can be in other locations such as the plantar-lateral border of the foot or the posterior ankle. The common effective conservative treatments for such an injury range from RICE (rest, ice, compression, and elevation), an ankle brace, orthotics, soft cast (Unna's boot), and physical therapy to retrain ankle proprioception. The most severe treatment involves surgical repair of the anterior talofibular ligament (Ferran & Maffulli, 2006; Karlsson & Sancone, 2006).
