- 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 jump1
How is the ligament injured?
- Changing direction with the knee caving in
- Planting and twisting with your foot planted
- Stopping suddenly on a straight knee
- Landing from a jump with the knees caving in
- Being hit on the knee from the front or the side
Young female athletes are more likely to tear their ACL compared to male athletes2
