The Anterior Cruciate Ligament is one of the most important ligaments of the knee joint [1] which gives stability to the joint. This ligament helps to hyperextend the knee joint or excessive backward movement of the femur [2] over the tibia. [3] ACL tear is one of the most common lower limb injuries seen in athletes especially in footballers, basketballers and skiers. This injury comes with a lot of pain and makes the athlete unable to perform sporting activities for many months. Read on to learn more about this injury and how it can be treated.
What Causes ACL Tear?
The Anterior Cruciate Ligament tear mostly occurs during a sporting activity or during other physical activities. The tear occurs when the knee is hyperextended, allowing the femur to roll backwards over the tibia. The following sequences of movement during sporting activities can lead to an anterior cruciate ligament tear:
- Landing from a jump when the knee joint is overly extended
- Halting suddenly when running on a high speed
- Changing direction when running on a high speed
These movements are common movements in sporting activities such as in basketball and in football. A direct hit to the knee during a rough tackle can also lead to an ACL tear. This tear can occur close to the tibia or the femur, but in most cases, it occurs at the midline.
