Recommended: Anatomy of the damage of an acl injury

The anterior cruciate ligament, also known as the ACL, is one of the four main ligaments within the knee that connect the femur to the tibia. It is also common to tear the ACL if one plays a sport. When one tears it, they hear or feel a pop, on might also feel that their knee just gave out. The knee will begin to swell up and be too painful to continue any sport or activity they were playing. The ACL is a ligament so when someone tears it, the ligament may no longer be attached to the bone. So the bones in your knee will move abnormally and start buckling. In your knee there are four ligaments, and they all keep your bones together and attached and prevent them from moving around. When one is torn then bones in your knee will move around

    The incidence and prevalence rate of anterior cruciate ligament (ACL) injuries in female athletes continues to increase over time (Prodromos, Han, Rogowski, Joyce, & Shi, 2007). With the growing rate in the amount of young women participating in sports, data has shown that the rate of ACL injury increases linearly with this participation ("The Relationship Between Static Posture and ACL Injury in Female Athletes," 1996). This epidemic of ACL injuries in female athletes, young or old, continues to be problematic in the athletic world. This problem not only affects the athlete themselves, but also the coaches and the sports medicine community.

    The anterior cruciate ligament (ACL) is one of the most important of your four major knee ligaments. The function of the ACL is to provide stability to the knee and minimize stress across the knee joint. It restrains excessive forward movement of the lower leg bone (the tibia) in relation to the thigh bone (the femur). It also limits rotational movements of the knee. “Greater external knee valgus and internal rotation moments have been shown to increase loading on the ACL in vitro and are thought to be associated with the increased risk of noncontact ACL injury” (Effects 2011). A tear to the anterior cruciate ligament results from overstretching of this ligament within the knee. It’s usually due to a sudden stop and twisting motion of the knee, or a “...

    In order for athletes to save their active lifestyles they need understand the ACL. The ACL is the most important ligament in the knee because it provides stability to the knee. Athletes have to be aware of the importance of the ACL and know its functions in order to preserve the ligament. The ACL otherwise know as the anterior cruciate ligament is the ligament in the knee that connects the upper leg bone which is the femur to the lower leg bone which is the tibia. The anterior cruciate ligament crosses with the posterior cruciate ligament inside the center of the knee joint to stabilize to the knee in movement.

    The most common knee injury in sports is damage to the anterior cruciate ligament (ACL) through tears or sprains. “They occur in high demand sports that involve planting and cutting, jumping with a poor landing, and stopping immediately or changing directions” (University of Colorado Hospital). The ACL is a ligament that runs diagonally in the middle of the knee and found at the front of the patellar bone. Its function involves controlling the back and forth motion of the knee, preventing the tibia from sliding out in front of the femur, and providing rational stability to the knee. Interestingly, women are more prone to ACL injuries than men. The occurrence is four to six times greater in female athletes.

  • All About the ACL

    In November of 2010, I was playing basketball in the fifth game of my senior season. It was just like any other game. However, I would soon find out otherwise. It was late in the game; I drove into the lane and got fouled hard. I was knocked so off-balance that I speared the floor with my knee. As soon as my knee hit the floor I heard a “snap” that I will never forget for the rest of my life. Little did I know at the time, that would be the last shot of my high school basketball career. Not long after my injury, I consulted a doctor. After getting an x-ray and an MRI, the doctor informed me that I had completely torn my ACL and would need to have surgery. An ACL tear can be a very devastating injury. The anterior cruciate ligament (ACL) is one of the four major ligaments within the knee. The ACL is one of the most commonly injured ligaments, injured by an estimated 200,000 patients each year. Of the 200,000 annual ACL injuries, surgery is performed in approximately 100,000 cases. There are many types of reconstructive surgery on the ACL. However, there is an alternative to surgery in the form of physical therapy.

    The Anterior Cruciate Ligament (ACL) attaches the femur, which is the thighbone, and the tibia, which is the shin, together (northstar). A torn ACL is one of the most excruciating experiences in an athlete’s life. It is the first thing that comes to mind when they hurt their knee on the field; for many it is their greatest fear. A torn ACL can sometimes mean the end of an athlete’s career. It can mean losing the chance to get that scholarship for young athletes, and it can also mean the end of those million dollar paychecks for those who have gone professional. A torn ACL can result in numerous surgeries, months of vigorous exercise and rehabilitation, and a sufficient amount of pain. It requires complete patience, for pushing too hard can result in further, more painful injury. Even after all that, an athlete is not guaranteed he or she will ever be able to play sports again.

    A 16-year-old, female high school soccer player, Lindsey Robinson, tore her anterior cruciate ligament (ACL) during a soccer game. Interestingly, she was not the only one in her team who injured her ACL, but several of her teammates have torn the same ligament as well during the soccer season. Lephart (2002) found that women involved in physical activity are more susceptible to acquiring the ACL injuries than men who are involved in the same physical activity (as cited in Ogden, 2002). According to “ACL Injury Prevention” (2004), the numbers of female ACL ruptures have increased for the past ten years. Over 1.4 million women have suffered from the ACL rupture, which is twice the rate of the previous decade.

    Everyday an athlete goes to practice or game, putting on a possibility of getting injured. A common one of those injuries is the tear of the anterior cruciate ligament, better known as the ACL. When sports that require quick pivoting and harsh landings became more popular such as soccer and basketball, ACL injuries quickly multiplied. Since kids, teens, and even adults usually focus on one sport it often occurs that they can overuse and exert their body causing injury to the ACL (Young Athletes 10).

    The majority of ACL injuries suffered during athletic participation are of the noncontact variety. Three main noncontact mechanisms have been identified planting and cutting, straight-knee landing and one-step stop landing with the knee hyperextended. Pivoting and sudden deceleration are also common mechanisms of noncontact ACL injury. Basketball, soccer, and volleyball consistently produce some of the highest ACL injury rates across various age groups. Other activities with a high rate of injury are gymnastics, martial arts, and running. In most sports, injuries occur more often in games than in practice. Many injuries have occurred during the first 30 minutes of play. One-reason physicians are seeing more ACL injuries in female patients that more women play sports, and they play more intensely. But as they continued to do more studies, they are finding that women's higher rate of ACL is probably due ...

  • Meniscal Injuries

    1813 Words  | 4 Pages

    In order to understand how the menisci can be injured, you must understand the basic anatomy of the menisci and why they are important. The menisci are two oval (semilunar) fibrocartilages that deepen the articular facets of the tibia and cushion any stresses placed on the knee joint. They enhance the total stability of the knee, assist in the control of normal knee motion, and provide shock absorption against compression forces between the tibia and the femur (Booher, 2000). Articular cartilage covers the ends of the bones that make up the joint. The articular cartilage surface is a tough, very slick material that allows the surfaces to slide against one another without damage to either surface. This ability of the meniscus to spread out the force on the joint surfaces as we walk is important because it protects the articular cartilage from excessive forces occurring in any one area on the joint surface, leading to degeneration over time (Sutton, 1999).

    Fibroblasts are the most numerous cells in this dense connective tissue. Fibroblast is responsible for the synthesis of collagen and extracellular matrix. Bands of such connective tissue are used to compose ligaments and tendons. Most tendons and ligaments require strength and inelasticity. Within tendons the collagen bundles are thick and parallel with flat nuclei of fibrocytes aligned with fiber bundles. Ligaments and tendons resist linear forces along their lengths. Ligaments are ropy, fibrous bands of tissue that connect bones to other bones. Ligaments surround joints in order to provide support to the joints and prevent dislocation and injury. The stability of the knee is due to four ligaments: The anterior cruciate ligament (ACL), posterior cruciate ligament (PCL), lateral collateral ligament (LCL), and medial collateral ligament (MCL). Ligament tares are common injuries in athletes; a torn anterior cruciate ligament often results from a one-time trauma, such as sudden twisting or an impact to the knee resulting in unable to continue to compete (Oliveria 2017). LCL tears are most commonly injures in sports that involve many quick stops, such as soccer and basketball, and

    High school and college athletes who have a history of concussion are 2 to 5.8 times more likely to experience another concussion compared to those who have no prior history of injury . Guskiewics et al. suggest that the increase of risk for another injury was higher during with the initial days after the first concussion. With repetitive exposure to concussions, the symptoms grow stronger each time. Although the symptoms disappear some time after the injury, symptoms can appear years later related to the damage done by the many concussions.
