Knee Injury Research Paper

The most common way for an ACL injury to happen is through non-contact, consisting of seventy percent of reported the reported injuries. As ACL injuries occur through contact or non-contact, they also result mostly from landing wrong from a jump, pivoting on one foot while running, planting a foot and changing directions, or landing on the knee straight and hyperextending the leg (Krick, 2001, pg.2).

The bones in the upper and lower leg of Human body are connected by complex pivotal hinge joint called knee. The upper and lower extremities are encompassed of tendons, cartilage, ligaments and muscle. Menisci, two concave pads of cartilage, disperse the friction created at the meeting of the ends of the tibia and femur. The key ligaments of the knee are Medial Collateral ligament (MCL), Lateral Collateral ligament (LCL), Anterior cruciate ligament (ACL), Anterolateral ligament (ALL), and Posterior Cruciate ligament (PCL).

A dislocated knee can happen when the bones that form the knee are not where they need to be. When a knee is dislocated, the ligaments that hold the knee together must tear. That is only in a really bad case. There is a type of dislocation that we all know where it’s just the patella (kneecap) that gets disrupted, and that’s called subluxation. In these kinds of dislocations, the ligaments aren’t torn, they’re just disrupted. If you treat a dislocated knee inappropriate or too late, there is a possible chance of losing the leg. Knee dislocations usually happen after major trauma or accidents. In example, falls, car wrecks, and any high speed injury. If your knee is ever dislocated, it will be deformed. It will not be in a straight

The body frame that we designed helps align the knee and leg. Included are two parallel support bars on each side of the knee which with the help of the strap will comfortably secure and support the knee. With the arched support frame above the main body reduces the force and impact experienced by the force of knee by disturbing the weight. While carrying out daily task the knee will be required to bend and move to get the individual from one point to another. Reducing the force from the knee will result in more support and less amount of damage given to the knee. However, an important addition to our knee brace is that it reduces the movement of knee joint itself without affecting the mobility of the person wearing it. Added above and below the knee are knee support straps which immobilize the knee and add extra support. Nonetheless, the back-side of the knee is unaffected by the support and if free to bend without obstruction. As a result, this knee brace reduces wear and tear on weak knees. Baring the weight of the individual across the whole leg instead of focusing it on the knee

The ACL extends posteriorly and laterally from a point anterior to the intercondylar area of the tibia to the posterior part of the medial surface of the lateral condyle of the femur (Tortora, 2009). In layman's terms, it extends diagonally in the middle of the knee joint connecting the shin and thighbones. The ACL is a complex structure that has an irregular nature. It has a multi vesicular structure that had been ignored for many years as it was originally thought to function as a simple band of fibers with constant tension as the knee moves. Multiple collagen bundles lead to the multivesicular nature of the ACL (Arnoczky, 1983). There are three functional bundles that make up the ACL; the anteromedial, intermediate, and posterolateral.

One can say that an Anterior Cruciate Ligament (ACL) tear, is an athlete’s worst nightmare. The ACL is one of four major ligaments that stabilizes and supports the knee. Its main function is to prevent anterior movement of the tibia off of the femur along with hyperextension. The ACL injury occurs from overstretching the ligament often caused by a sudden change in direction, awkward landing from a jump, sudden deceleration, or even a direct collision (3). More importantly, three out of four ACL injuries occur from non-contact instances (2). During the onset of the injury, a distinct popping noise can be heard with an instantaneous sharp pain causing the athlete to fall to the ground. It is the most common type of injury in the knee in the

In pro-leagues such as the NBA, NFL, MLB, and many more, there is one common occurrence and it’s injuries. Sports players like Derrick Rose tore his anterior cruciate ligament (ACL) because of improper landing and many more injuries have happened as a result of improper landing and not wearing certain gear. It is important for everyone to know how to prevent an injury or recover from an injury. Following these steps will help anyone prevent or recover from an injury.

The anterior Cruciate Ligament also known as the ACL is located in the knee behind the patella. It attaches to the tibia at the anterior

ACL injuries have brought financial burden to society, and caused devastating consequences to patients’ quality of life. Based on an estimated 200,000 cases of ACL injuries in US each year, annual cost of ACL injury is estimated to be US$4 billion for surgical treatment

The knee joint supports the body weight of a person while absorbing shock to the body. The main function is to allow your lower leg to bend. Normal range of motion of the knee joint is considered to be 0 degrees of extension (straight knee joint) to 135 degrees at full flexion. Different sports and training regimes can change the amount of hyperextension and flexion. E.g. A weightlifter than has bigger bulkier muscles may not be able to fully flex the knee while a long distance runner might have leg muscles that are smaller in size which will allow the knee to fully

In an article in the New York Times Magazine, written by Jane E. Brody, she talks about ankle injuries and how to help them. She states that over 28,000 ankle related injuries happen daily in America, and to never purposely put your ankles at risk. Ankle injuries should never be taken lightly because they can lead to many ankle problems. Ankle sprains are the most common mishap in sports. There are many ways to injure your ankle. The most widely used treatment, is (RICE) or rest, ice, compression, and elevation. Trying to walk will make it worse. To know if you have an ankle injury you may look for unnatural swelling and tenderness. If you have pain and symptoms of an injured ankle you should immediately begin (RICE). After your ankle

The Anterior Cruciate Ligament (ACL) is the most commonly injured ligament in the body (Spindler, 2008). Griffin (2005) estimated that around 80 000 to more than 250 000 ACL injuries occur each year. An anterior cruciate ligament rupture (ACLR) can be a devastating injury to an athlete, as they encounter the possibility of reconstructive surgery alongside extensive months of rehabilitation. Also many athletes are unable to return to their former level of athletic performance within the first postoperative year, with many athletes unable to return to play at all (Panariello, 2015).

Did you know that 3.5 million kids under the age of 14 get medical help for sports each year. Even though that little wincing pain might be nothing, it could turn into something. Many children get pushed so hard playing their sport they don't even notice that knee injury and they're told to shake it off, but then it gets worse and can ruin their whole career.

Now that the warmer weather has arrived, more and more people are getting active outside. With spring sports, strenuous exercises, and other workout routines starting, springtime is when many injuries occur. One of the most common areas susceptible to injuries during the spring is the ankle. If you have ever been active or participated in a sport, you may have ‘twisted’ your ankle once, if not multiple times. However, when the ankle swells and causes pain or discomfort, it can be difficult to tell whether the ankle is sprained, strained, or broken. All three of these common ankle injuries are not easy to differentiate, but it is critical that the proper medical care is received if the injury is severe or if the ankle is fractured.

Sports are great fro children and young adults. They promote physical activity and fitness. Sports are phenomenal, but sometimes involve injuries to players. Many children, adults, and young adults around the world suffer injuries from sport activity, whether it may be a broken ankle to a severe concussion. These injuries are not inevitable. The injuries could be prevented by taking precautionary measures and having parents and adults involved.
