Sports like football are laden with knee injuries because they involve hits to the outside of the knee. Contact to the outside of the knee can cause meniscus tears, ACL tears and MCL tears to all occur at once.
What is The Anterior Cruciate Ligament
The anterior cruciate ligament (ACL) attaches to the femur (thigh bone) and the tibia (shin bone) and essentially prevents the femur from sliding too far forward. Like other ligaments in the knee, the ACL provides stability and allows movement such as rotation of the knee. Injuries to the ACL cause both pain and swelling in the knee.
According to the best Parramatta knee specialist team in Westmead Hospital in Sydney Australia, ACL tears lead to other injuries such as arthritis and cartilage tears. Because the ACL helps stabilize the knee, injuries to the ACL make the knee less stable. When the knee is less stable, sudden pivoting movements are extremely difficult and oftentimes lead to arthritis and cartilage tears.
Treatment for ACL Injuries
Once the ACL is completely torn, it cannot heal back together, even when the ends are sewn back together. The most common treatment for ACL tears is reconstructive surgery. Reconstructive surgery involves removal of the torn ends of the ACL and replacement of those ends with a graft. The graft is secured by tunnels that are made in the tibia and femur.
Medial Collateral Ligament Injury
A direct blow to the outer aspect of the knee commonly causes injuries to the MCL. Those athletes who play football and soccer are at the highest risk. When the knee is forced sideways, the MCL can tear and result in knee pain. Swelling will occur with an MCL injury as well and the knee will become unstable and give way.
When the MCL is torn severely and cannot heal correctly, surgery is necessary. This will involve grafting a piece of tendon to allow the portions of the torn ligament to connect to. Most of the time, however, these injuries can be treated without surgical intervention.
The medical collateral ligament (MCL) is located in the inside of the knee joint and functions to prevent the joint from opening up. Like the ACL, the MCL attaches to both the femur and tibia and controls stability in the knee. Injuries to the MCL involve pain and swelling in the knee.
Usually, MCL injuries occur when the knee joint buckles after being hit. Because it functions to prevent the inside of the knee joint from opening up, pressure to the outside of the knee can injure the MCL. In addition to hits to the outside of the knee, stretching the MCL too far can also cause it to tear.
Treatment for MCL Injuries
MCL injuries heal quickly and rarely require surgery. Resting the knee, icing the injury and taking anti-inflammatory medications can help the injury heal more quickly.
Severe sprains to the MCL sometimes require a knee brace. Usually, even patients with knee braces are able to resume normal activity and athletic activity as soon as they are no longer experiencing pain. If the injury is even more severe, physical therapy and a 3 to 4-month break from normal activity is required.
