Football season is a GO! and so are injuries

With the football season starting up again and everyone talking about creating their fantasy football teams, injuries are also of interest. We always hear of them having concussion but there are definitely injuries of the lower limb that can keep players out of the season. Dustin Keller for the Miami Dolphins recently injured his right knee against the Houston Texans. He had torn ACL, PCL, and MCL, which was no surprise that led to a dislocated knee. So what do those acronyms stand for and why do they cause such serious injuries?
Here’s a quick explanation:

Anterior cruciate ligament (ACL): It is one of the four ligaments that attaches the front of the tibia to the femur and it is located inside the knee. It prevents the lower leg from sliding out in front of the upper leg. Tears of the ligament often result from frontal impact on knee or thigh when the foot is fixed. A test used to determine if your ACL is torn is called anterior drawer sign because the leg will slide forward like opening a drawer.

Posterior cruciate ligament (PCL): This is like the stronger brother of the ACL that helps hold the upper and lower leg together. This ligament prevents the lower leg from sliding out behind the upper leg. Injury usually happens by overextending the knee, such as a direct blow to the flexed knee or motor vehicle accidents (“dashboard injury”).

Medial collateral ligament (MCL): It is located on the inner surface of the knee connecting femur and tibia. Part of the ligament Stabilize the knee, promote locking of joint, and prevents the knee from bending inward. Tackling is a common cause of injury to this ligament.



As you can see with the picture to the right that the ACL and PCL cross each other inside the knee joint and that is  why they are called the cruciate ligaments. I hope that this helps some people understand each of these injuries and since he tore 3 of the 4 ligaments that help hold his knee together it is no wonder he was left with a dislocated knee.

    Good sharing, Knee injuries is a common problem with many causes, from acute injuries to medical conditions. Normally people will believe surgery is the only way to relief knee pain, in fact, some may ask how to cure knee pain without surgery. Yes there are ways like using Unloading bracing technology, having ergo mattress etc. More information:
