where is acl

The ACL is in the knee , running through the center of the joint and connecting the thigh bone (femur) to the shin bone (tibia).

Quick Scoop

  • The ACL (anterior cruciate ligament) is one of the main ligaments that stabilizes your knee joint.
  • It lies inside the knee, forming part of an “X” shape with the posterior cruciate ligament (PCL), with the ACL toward the front and the PCL toward the back.
  • Anatomically, it runs diagonally from the back of the femur down to the front/central part of the tibia, in the center of the knee.

If you’re feeling your own knee

  • The ACL is deep inside the joint, so you cannot directly feel it from the outside like a tendon or muscle.
  • Pain or injury from an ACL tear is usually felt deep in the center of the knee, often after a twist, pivot, or sudden stop, especially in sports.

In everyday terms: the ACL is the internal “check strap” in the middle of your knee that keeps your shin bone from sliding too far forward and helps control rotation.

TL;DR: The ACL is a ligament inside the center of your knee, connecting the femur to the tibia and helping keep the joint stable.
