Anterior Cruciate Ligament (ACL)

Improved Essays
Anterior cruciate ligament (ACL) injuries are a increasing concern for athletes worldwide. Over 120,000 ACL injuries happen every year affecting more female athletes at the high school and collegiate levels. (Gornitzky Al, Lott A, YellinJl, Fabricant PD, Lawrence JT, Ganley TJ. 2015) With such a growing problem preventative measures are just as important as rehabilitation procedures. Neuromuscular training is gaining popularity as a preventative measure for these injuries. Research has shown neuromuscular training can reduce the risk of injury. (Labella Cyntha, Huxford Michael, Grissom Joe, Kim Kwang-Youn, Peng Jie, Christoffel Kaufer Katherine 2011; Pasanen Kati, ParkkriJari, Pasanen Matti, Hiilloskorpi Hannele, Makinen Tanja, Jarvinen Markku, …show more content…
The knee joint is the area that connects the femur and tibia with the patella acting as a covering for the joint. The ACL has two main purposes. They are to prevent the tibia from coming forward and the second is to provide knee joint stability. Injures to the ACL happen in either through contact or noncontact. Contact is defined as direct contact to the knee by another player or object during the course of a game. 4 Noncontact is defined as an injury sustained without outside contact by another player or object on the field. 4 It has been reported that over 70 % of these injuries are classified as non-contact. (5,7)

ACL injuries are referred to as sprains. They are classified through numbers ranging from one to three. A grade one sprain is a slightly damaged ligament, grade two is a partially torn ligament, and grade three is the most severe a full tear of the ligament. ACL sprains typically happen along with other injuries. ACL sprains generally happen in one of two ways. The first is through contact. This is defined as The other is through noncontact. It has also been reported that ACL sprains have a greater likelihood of occurring in female athletes compared with male counterparts in the same

These programs are currently known as Sports metrics and the PEP (Prevent Injury and Enhance Performance) ACL injury prevention program. Those original studies were not perfect by any means. The Hewett study that incorporated the Sports metric program had a few limitations. It would’ve been a stronger study as a randomized control trial and also could’ve done a better job of distributing players among the intervention and control group. Mandelbaum’s study in 2005 also would’ve been stronger evidence as a randomized control trial. Also, the way they reported injuries could have been performed better. I would’ve preferred an athletic trainer report the injuries compared to a questionnaire completed by a player and a form faxed by the

    There are two main risk factors when it comes to ACL tears, what sports an individual plays, and the gender of the individual. There are certain sports where ACL tears are more common than in other sports. This is due to the certain movements of the knee required by each different sport. ACL tears are especially common in soccer, basketball, and football players. All of these sports require planting, cutting, straight-knee landings, pivoting, and sudden deceleration.…

    Holding these bones together and providing movement and stability are the lateral collateral ligament (LCL), the medial collateral ligament (MCL), the anterior cruciate ligament (ACL), and posterior cruciate ligament (PCL) (“Knee Anatomy”). The top of the tibia is also covered by menisci acting mainly as shock absorbers (“Knee Anatomy”). As Cowl turned sharply to avoid being tackled, he felt a pop in his right knee. Following Cowl’s injury, an anterior drawer test, a Lachman test, and a pivot shift test were all performed. Through these tests, the trainer confirmed his suspicion of an ACL tear to the right knee.…

    Case Study #3 With the given information about the blow to the tibial tuberosity causing displacement of the tibia posteriorly relative to the femur, the structure most likely injured is the posterior cruciate ligament because it is located on the posterior side of the patella and posterior displacement of the tibia on fixed femur is restricted by the posterior cruciate ligament. The posterior cruciate ligament is the strongest ligament in the knee joint and helps with stability. Once the posterior cruciate ligament is torn or stretched, it loses its stability. There are many ligaments that make up the knee joint, also known as a hinge type joint which perform tasks such as flexion and extension. The tibiofemoral and patellofemoral are joints of the knee which aid in flexion and extension of the knee.…

    ACL tears happen to both men and women, but according to studies by the NCAA’s Injury Surveillance System “female athletes are as much as four times more likely to suffer ACL Injuries than their male counterparts” (Clardie). One of the most common beliefs as to why this happens is because women possess a different bone structure than men. Women almost always have a wider hip and pelvic structure than men; because of this, women experience increased stress on their knee compartments, ligaments, and muscles (Schmidt). Specifically, the angle at which the femur connects to the knee is wider than males, so women have pressure surrounding their ACL (Musgrave). Also, women have a tendency to have “valgus knees,” which means that women commonly have knees that angle in and touch one another when they are straightened.…

    A 30-year-old skier takes a sharp turn on the slopes and hears a dreaded “pop” in his right knee. He has ruptured the anterior cruciate ligament (ACL)—a band of tissue that’s important for stabilizing the joint. After icing, compressing, and elevating his swollen knee, he visits the doctor. Now it’s time to decide on treatment. If he’s an elite athlete or has additional knee damage, the choice is fairly clear: reconstructive surgery to replace the ACL, plus intense physical therapy.…

    “About two-thirds of injuries happen during movements like twisting, pivoting, or moving sideways, while the rest are caused by direct contact with an object or another person.” (Humphries) There is a wide variety of why the ACL tears. Some ACL tears that have occurred in the past have included things like a narrow femoral notch, which is the space between the two femoral condyles. This would likely develop into a non-contact injury, because due to the narrow notch, the ACL would be getting pinched and stressed.…
