Anterior Cruciate Ligament (ACL) is one of the four ligaments in the knee joint The ACL runs diagonally inside the knee like a rope to make the joint stable!
The ACL keeps the knee stable when changing directions quickly or when landing from a jump.[1]

How is the ligament injured?
There are many ways that an ACL can be injured. Here are just a few of examples:

Changing direction with the knee caving in
Knees Caving IN

Twisting with your foot planted
foot planted

Stopping suddenly on a straight knee
sudden stop

Landing from a jump with the knees caving in

Being hit on the knee from the front or the side

Additionally, your biological sex plays a role as well. Research has indicated that young female athletes are more likely to tear their ACL compared to male athletes.[2] Read more about it in this blog post.
