What are knee ligaments and what are their injuries?

Ligaments are bands of tough, elastic tissue that connect bones to each other and provide strength and stability to the joint. In the same way, Knee ligaments are the elastic bands of connective tissue that hold the knee together. There can be various causes of knee ligament injuries including an injury caused by an accident or while playing sports, etc. When ligaments are injured, the knee joint may become unstable. A damaged ligament may limit proper knee movement and may cause an inability to turn, twist, or pivot the leg.

  • Anterior cruciate ligament (ACL):  This ligament lies in the center of the knee. It controls the rotation & forward movement of the tibia (shin bone).
  • Posterior cruciate ligament (PCL): This ligament lies in the center of the knee. It controls the backward movement of the tibia (shin bone).
  • Medial collateral ligament (MCL): This ligament provides stability to the inner knee.
  • Lateral collateral ligament (LCL): This ligament provides stability to the outer knee.
