    In today’s society, injuries occur all around us: from a small paper cut, a tear of a ligament, or a bone breaking in the body. The anterior cruciate ligament (ACL) is one of the four central ligaments that stabilize the knee (Ref). This ligament prevents the tibia from sliding from the front of the femur and runs diagonally in the middle of the knee (ref). It is estimated that 70 percent of these tears occur through non-contact, while the other 30 percent occur from direct contact, whether it be from an outside object or player in sports (ref). This injury may occur when an individual is decelerating immediately while sidestepping, which may cause an uncomfortable landing on the knee joint (ref). Injured ACLs can be replaced by a substitute…

The posterior cruciate ligament is the strongest ligament in the knee joint and helps with stability. Once the…

    The posterior cruciate ligament(PCL) is one of, if not, the strongest ligament in the knee and often described as the “primary stabilizer of the knee”(emedicine, Charles S Peterson, MD). While this is not one of the more common of the 4 stabilizing knee ligaments, it serves a great purpose. The posterior cruciate ligament is twice as strong and twice as thick than it’s “sister” anterior cruciate ligament (ACL). The PCL is extends from the lateral surface of the medial femoral condyle to the…

The anterior cruciate ligament tear is one of the most common sport injuries. Among knee injuries, the Anterior Cruciate Ligament (ACL) is one of the most commonly disrupted ligaments in the knee (Boden, 2000). This injury happens from changing…

    The Posterior Cruciate Ligament (PCL) is located in the knee behind the Anterior Cruciate Ligament (ACL). It is the strongest ligament in the knee and is important in knee stability. The two cruciate ligaments which cross each other to form an “X”, control the back and forth motion of your knee. A ligament is a tough, relatively inelastic band of tissue that connects one bone to another. As one of five ligaments in the knee, the PCL connects the femur to the tibia and prevents the tibia from…
