The anterior cruciate ligament can tear if an injury stretches it too much. The tear might be partial (through a part of the ACL) or complete (through the ACL).
What are the many forms of ACL tears?
When you injure a ligament, your healthcare professional may grade the damage on a one to three scale, with three being the most severe:
Grade One: Your ligament has been stretched, but it still supports the knee joint.
Grade Two: Your ligament has been stretched and loosened. It's slightly ripped. (This is a very unusual grade.)
Grade Three: Your ligament has been ruptured - separated into two parts. This is a major injury.
Causes
The great majority of ACL tears are non-contact injuries. This suggests that they are not caused by another player kicking your knee. They can occur in several situations, including when you:
Stop running abruptly.
Take it easy when running.
After a leap, you land uncomfortably.
Alter your direction abruptly, turning your knee.
Collide with someone else, as in a football tackle.
