An anterior cruciate ligament (ACL) injury is a tear or sprain of this tough band of tissue that helps link your thigh bone (femur) to your shinbone (tibia).
You might require reconstructive surgery if the anterior cruciate ligament (ACL) in your knee is torn. A strong tissue band known as the ACL connects the thigh bone to the shin bone at the knee joint. It provides support to the knee joint and runs diagonally through the inside of the knee.
The knee cannot flex outward because of it. The ACL, or anterior cruciate ligament, is located in the center of the knee. The shin bone cannot slide in front of the thigh bone because of this. The ACL cooperates with the posterior cruciate ligament (PCL).
