Getting to know the anterior cruciate ligament.
Ligaments are strong tissues that connect bones. The anterior cruciate ligament (ACL) is located in the center of the knee joint and runs diagonally from the back of the femur to the tibia. This ligament controls the range of motion of the knee and shin, allowing them to move at various angles. If there is a strong twisting force, the ACL can rupture, and the stability of the knee, which prevents the tibia from sliding forward under the knee or twisting, is lost.
Knee injuries resulting from a ruptured anterior cruciate ligament are one of the most common types of knee injuries, accounting for about 40% of all sports injuries. They usually occur during sports such as skiing, tennis, squash, football and rugby. If left untreated, the meniscus or articular cartilage can become overloaded with abnormal forces, leading to osteoarthritis.
