Types of Knee Ligaments

Ligaments in the Knee

The four main ligaments in the knee connect the femur (thighbone) to the tibia (shin bone), and include the following:

  • Anterior cruciate ligament (ACL) - The ligament, located in the center of the knee, that controls rotation and forward movement of the tibia (shin bone).
  • Posterior cruciate ligament (PCL) - The ligament, located in the center of the knee, that controls backward movement of the tibia (shin bone).
  • Medial collateral ligament (MCL) - The ligament that gives stability to the inner knee.
  • Lateral collateral ligament (LCL) - The ligament that gives stability to the outer knee.
