Cranial Cruciate Ligament (CCL)

What is a Cruciate Ligament?

There are 2 ligaments in the stifle (knee) that are called the cruciate ligaments because they cross each other. One runs from the back of the femur (thigh bone) to the front of the tibia (shin bone). This one is called the cranial cruciate ligament. The other one runs from the front of the femur to the back of the tibia and is called the caudal cruciate ligament. Cruciate ligaments are important for the hinge joint function of the stifle joint. They help to keep the stifle aligned and the cranial cruciate ligament especially prevents internal rotation of the stifle, forward displacement of the tibia, and hyperextension.
