A torn ACL is one type of knee injury. The anterior cruciate ligament (ACL) connects the upper and lower leg bones around the knee. It also helps stabilize the leg during movement. But if a player twists his knee -- or it gets hit -- the tendon can be torn or disconnected from the bone. A person might feel a pop and his knee might give out. RICE -- rest, ice, compression, and elevation -- is standard treatment, but surgery may be required, especially in active patients. A torn ACL can keep a player benched for a few months.
