What are major ligaments in the knee?

ANSWER

Ligaments are bands of tough elastic tissue around your joints. They connect bone to bone, give your joints support, and limit their movement. There are four major knee ligaments that connect your thighbone (femur) and shinbone (tibia):

  • Anterior cruciate ligament (ACL): Located toward the front of your knee. It controls forward movement and rotation of your shinbone.
  • Posterior cruciate ligament (PCL): Located toward the back of your knee and controls backward movement of your shinbone.
  • Medial cruciate ligament (MCL): On the inside of your knee and gives that area stability.
  • Lateral collateral ligament (LCL): On the outside of your knee and keeps the area around it stable.
