Knee Injury Research Paper

Knee injuries are all too common in athletics, and orthopedic surgeons say there’s a growing number of teens and children suffering them, especially torn ACLs. The ACL or the anterior cruciate ligament connects the thigh bone to the shin bone, and it also helps stabilize the knee.
Now, more than 40 years since the passage of Title IX, research shows girls are more likely than boys to suffer a torn ACL. In fact, experts say it’s the most common knee injury among women athletes at all levels; high school, college and professional. Orthopedic surgeons say female athletes most likely hurt their knees when they plant and twist their leg, such as when playing soccer, or landing that jump shot.
Sports medicine experts say the large number of athletes with knee injuries has to do with over-training and excessive stress on the knee joint during growth stages when the bones and soft tissue are not fully mature. With so many young athletes sidelined with ACL injuries, more parents, coaches, doctors and physical therapists are now looking for ways to prevent them.

Many experts say the way girls and women use their leg muscles during sports, and how they land after jumping may be the biggest cause. The muscles in front of the thigh that help to straighten the knee (the “quadriceps”) tend to be stronger and tighten more quickly than the muscles in back of the thigh that bend the knee (the “hamstrings”) females. Females naturally land from jumps with their legs straight, at both the hip and knee. All of these put more stress on the ACL. Physical therapists and coaches need to teach athletes better exercises that will correct

    For example, in football or soccer, a player plants his or her leg, slows down quickly, and cuts into a different direction. Depending on the direction of the cut, this sudden stop and twist of the knee can put too much stress on the ACL and cause it to tear (Slowik 2). While it is possible to tear an ACL in a non-contact sport, most ACL that are torn during sports occur while playing a contact sport. “One study showed that contact resulted in 93% of injuries in a ground of 226 patients while non-contact sport resulted in the remaining 7%” (Curran, Kum, Tanyu, Wyatt 1). The other risk factor for ACL tears is gender.…

    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.…

While it is a pretty long surgery, the results are very rewarding.…

    This is a weak position for the knee and it cannot support the force and therefore, buckles and the ACL is injured. The theory this study is testing is if the hip musculature can support the knee. If a person has good muscle strength in the hip and gluteus medius, that may help with the valgus force and reduce the amount of injury. There is evidence to show that when adding hip strengthening exercises to a prevention program, it helps reduce the risk of ACL injury.…

    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 posterior aspect of the tibia. The term cruciate translates to “criss cross” which describes the PCL and ACL.…

    The Injury The ACL or Anterior Cruciate Ligament attaches from the front of the tibia to the back of the femur. It is an important ligament in which keeps the tibia from sliding too far forward in relation to the femur bone and provides stability to the knee joint in sagittal plane movements. Injuries to the ACL are very common in individuals who have the knee in an awkward position such as stopping suddenly while jogging or sprinting, a rapid change in direction, and an abnormal landing stance that leaves the knee joint locked. Your ACL can be injured if your knee joint is bent backward, twisted, or bent side to side.…

    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.…

    People get their ACLs torn in car crashes. A simple trip or fall that twists the knee can also result in a tear. Anyone can damage their ACL, but female gymnasts and soccer players are especially prone to ACL tears. There are several possible explanations for women being more vulnerable to ACL injuries, including differences in muscle strength, alignment, and estrogen levels that can loosen ligaments. There’s also some evidence that women are more likely than men to turn their knees inward when changing direction suddenly, placing added strain on their knees and…
