Home > Types of ACL Injuries
anterior cruciate ligament (ACL) injury often is
called a sprain. A sprain occurs when the threads or fibers of the
ligament stretch or are torn.
See a picture of the
knee and the ACL.
An ACL injury is classified as a grade I, II, or III sprain.
An ACL avulsion occurs when the ACL is torn away from either the
upper leg bone or lower leg bone. This type of injury is more common in
children than adults.
An avulsion fracture occurs when the ACL is torn away from the leg
bone with a piece of the bone.
