title: MR arthrography of the ankle
abstract: Injuries to the lateral ankle ligaments are extremely common. Many patients with acute injuries to the lateral ligament complex develop chronic ankle instability that requires surgical intervention. MR arthrography of the ankle plays a valuable role in identifying those patients who are most at risk for the development of chronic instability. MR arthrography of the ankle also aids in preoperative planning and in differentiating among other entities that can present as ankle instability.
