The anterior cruciate ligament (ACL) is one of the most common ligaments to be injured. The ACL is often stretched and/or torn during a sudden twisting motion (when the feet stay planted one way, but the knees turn the other way). Skiing, basketball, and football are sports that have a higher risk of ACL injuries.
Knee Ligaments. The knee ligaments can be split into two pairs, the collateral ligaments (around the sides of the joint) and the cruciate ligaments (inside the joint). Ligaments are thick fibrous bands like ropes and their job is to provide stability by holding bones together.
