What Is ACL?

In medical terminology, the acronym ACL stands for anterior cruciate ligament, which is a major ligament found in the knee. The ACL is located at the center of the knee and is one of four ligaments that join the femur with the tibia.

An ACL injury can occur if this ligament tears or is overstretched. Some causes for an ACL injury are an impact to the side of the knee in sports like football or basketball and the knee joint being overextended when turning or stopping quickly. ACL injuries can be either partial or complete tears of this ligament. The main symptoms of an ACL injury are pain and knee inflammation.

Initial non-surgical treatments for this injury are lifting the leg, placing ice packs on the affected area, and taking pain relievers. A torn ACL may require surgical repair.
