Ligaments are bands made from connective tissue and they have a lot of strong collagen fibers. Because they play very important role holding bones together and providing the stability around a joint.
The ligaments in the knee connect the femur (thighbone) to the tibia (shin bone).
There are 4 main ligaments of the knee:
· Anterior cruciate ligament (ACL). ACL located in the center of the knee and controls rotation and forward movement of the tibia – prevents the femur from sliding backward on the tibia
· Posterior cruciate ligament (PCL). PCL also located in the center of the knee and controls rotation and backward movement of the tibia, in other words prevents the femur from sliding forward on the tibia
· Medial collateral ligament (MCL). Gives stability to the inner knee and prevent the femur from sliding inside.
· Lateral collateral ligament (LCL). Gives stability to the outer knee and prevent the femur from sliding outside.
