The knee joint itself involves a multitude of structures to keep it stable and strong. The Anterior Cruciate Ligament (ACL) is one such structure that helps achieve these objectives. It originates from the posterior (back) part of the femur and attaches to the anterior (front) part of the tibia. The Posterior Cruciate Ligament (PCL) meanwhile, originates from the anterior part of the femur and attaches to the posterior part of the tibia. These two ligaments crosses in the middle and provide specific stabilities to the knee.
The ACL is important in securing the knee joint by preventing the forward movement and rotation of the tibia (lower leg bone) in respect of the femur (thigh bone).
There are many ways that a knee can be injured. On the one hand, there could be an obvious traumatic incident, where you were tackled while playing football. On the other hand, it could also be due to an inconspicuous activity, where you were simply running and trying to turn one way and injured yourself.
Most ACL injuries, in fact, are done via the later method. There may also have been a factor of jumping/landing prior to the injury.
A full tear of the ACL, may actually not cause significant amount of pain in some cases. In fact, some athletes would feel that they can continue their sporting commitments, only to find themselves unable to perform due to significant instability in the knee joint.
