The Anterior Cruciate Ligament’s role in movement Michael Corrada Texas Tech University Quiz 1, 3, 4, 5, 6 ABSTRACT The anterior cruciate ligament is one of the most injured parts of the knee for young and old alike. With the advancements in medical technology we are able to provide reconstruction and physical therapy to those with this type of injury. Most anterior cruciate ligament tears come from cutting or sharp pivoting or when the lower leg is planted and the upper leg twists. This causes a grade three sprain which is a tear. Upon injury to anterior cruciate ligament the athlete normally hears a popping sound seventy percent of the time. Other signs of a tear include rapid swelling of the knee caused from the blood from†¦show more content†¦Most often the issue of many athletes of all ages is that they have an issue with their anterior cruciate ligament. The key ligament in many movements done that could give you the upper hand on your opposition. These movements include cutting, pivots, planting, and sudden acceleration and deceleration. Normally the ligament is just a part of our everyday walking, but it is when sharp or sudden pressure is applied that is when our knee can go into hyperextension or over rotation causing a sprain of the ligament. These sprains are classified as grades and split up into three different categories. Grade one sprains are akin to a bruise on the ligament and do not require a long recovery time. Grade two sprains are a slight tear in the ligament and can have around a month recovery time. Grade three sprains are a complete tear of the ligament and normally require surgery because that ligament will not heal on its own. If the injured person decides to undergo surgery it could be a six month recovery time with intense physical therapy. If they do not want to have surgery their movement of that knee will never be the same and could lead to further injury of surrounding ligaments and cartilage. Grade three sprains are the most severe and are normally the case when speaking about and anterior cruciate ligament injury. When an athlete sustains an anterior cruciate ligament injury they normally hear a â€Å"pop† and looseness in their knee.
