<< Back to Surgery and ProceduresNormal Anatomy
The ankle joint connects the foot with the leg. The ankle joint allows the foot to move upward and downward and in an inward and outward motion. Muscles, tendons, and ligaments surround the ankle providing the stability the ankle joint needs for walking and running.

Type I Ankle Sprain
The most common way the ankle can be injured is by an ankle sprain. When an ankle is sprained ligaments on the ankle are either stretched, partially torn or completely torn. The most common type of sprain is an inversion injury, where the foot is rotated inward. Ankle sprains can range from mild, to moderate, and severe. Type 1 ankle sprain is a mild sprain. It occurs when the ligaments have been stretched or torn minimally.
