Where is the ACL Located?

The anterior cruciate ligament (ACL) is found in the knee joint in front of the posterior cruciate ligament. The ACL and PCL control the back and forth motion of your knee. The ACL is also important for providing rotational stability to the knee and preventing the tibia from sliding out in the front of the femur.

    • Pain
    • Swelling
    • Tenderness
    • Instability of Your Knee
