Acute Cruciate Ligament Injury

* Acute Cruciate Ligament Injury The ACL, or Acute Cruciate Ligament, is one of the most important ligaments in the body. This ligament is located at the knee. There are four thick bands of tissue, called ligaments, which stabilize the knee and keep its movement in one plane. There is the medial collateral ligament, lateral collateral ligament, posterior cruciate ligament, and the anterior cruciate ligament, which forms an X with the PCL inside the knee joint to prevent the knee from sliding back to front and vice-versa. The ACL provides stability to the knee and minimize stress across the knee joint. It limits rotational movements of the knee. It restrains excessive forward movement with the tibia (lower leg bone) and femur (thigh bone).…show more content…
Researches show that non-contact ACL injuries can be reduced from 20% to 80% by engaging in neuromuscular training to enhance balance, proper movement patterns, and muscle strength. But, we still can’t avoid the fact that if we engage in athletic injuries, there is a chance that we might get an ACL injury. We can diagnose ACL injuries in different ways. There is the anterior drawer test, Lachman test, and the pivot shift test. The anterior drawer test is used by physicians to detect ruptured ligaments. The patient should be lying down faced up with the hips flexed to 45 degrees and the knee to 90 degrees. The examiner grasps the tibia and pulls it forward. Excessive displacement of the tibia anteriorly indicates a torn ACL. In the Lachman test, the patient’s knee is flexed 30 degrees, and the leg is rotated externally. One hand is placed behind the tibia and the other on the thigh. Pulling anteriorly on the tibia, an intact ACL should prevent forward translational movement of the tibia. If not, the ligament might be injured. This test is considered more superior than the anterior drawer test. In the pivot shift test, the knee is extended and rotated internally. Pressure will be applied on the lateral side of the knee. A crash at 30 degrees indicates a positive
