...This article goes into depth about the causes and treatments for the ACL which stands for anterior cruciate ligament, one of the main four ligaments in the knee. The knee is supported by the MCL (medial collateral ligament), LCL (lateral collateral ligament), PCL (posterior cruciate ligament) and ACL. The ACL goes through the middle of the knee, it helps provide motion stability to the knee, it is also known as one of the most commonly injured ligament. People who take part in risky sports such as football, dance, soccer, gymnastics, etc are more likely to tear their ACL. When the ACL is injured it’s likely there are other ligaments injured or possible bruising on the bone. An MRI can help accurately depict what has been hurt. The ACL is...

...torn anterior cruciate ligament (ACL). MRI of the left knee dated 08/24/16 showed truncated posterior horn of the medial meniscus concerning for a partial-thickness radial tear. There is a torn anterior cruciate ligament. Osseous contusion versus reactive bone marrow edema of the central weightbearing aspect of the medial femoral condyle is noted, with an overlying high-grade chondral fissure. There are mild degenerative changes of the knee as described with moderate grade partial-thickness articular cartilage loss of the posterior aspect of the lateral tibial plateau. Findings are of indeterminate age....

...so common because of how complex the knee is. The knee is formed by three bones, the patella the tibia and the femur. In the knee there are two cartilage disks called menisci. These menisci give padding to the knee and allow it to glide smoothly. The knee is stabilized by tendons muscles and four important ligaments. The anterior cruciate ligament (ACL), posterior cruciate ligament (PCL), medial collateral ligament (PCL), and the lateral collateral ligament (MCL)....

...The anterior cruciate ligament is one of the four major ligaments that stabilize the knee joint.1 The ACL’s main function is to prevent the tibia from sliding forward relative to the femur, otherwise known as anterior tibial translation. 1 The ACL plays a crucial role in the prevention of excessive knee extension, knee varus and valgus movements, and tibial rotation. 1 An intact anterior cruciate ligament allows for the protection of the menisci from shearing forces that occur during athletic maneuvers such as landing from a jump, pivoting, or decelerating from a run. 1 Without an intact ACL, the knee will become very unstable limiting the types of activities that can be done while suffering from the injury. 1 The lateral femoral condyle has...

...ACL Reconstruction Anterior Cruciate Ligament or ACL is injured in many adolescent athletes. The ACL is a very common injury that happens to the ligament in the knee. The ACL is one of the four strongest ligament in the knee. “The bones of the skeleton are joined together by ligaments, which are strong, fibrous bands or sheets of connective tissue” (Kendall, McCreary, Provance, Rodgers, & Romani, 2005, p.9). ACL helps to support the knee when being active in sports or in situations where there is a lot of twisting and pivoting at quick speeds. After the ACL has been torn, many adolescents need to have the ligament repaired. There is several types of repair. Hamstring graft and Patella Tendon graft are the most common. Studies show both...

...1. The article that was read talked about adolescent girl athletes having a higher risk in knee injuries than boys. It states that girls are eight times more likely to injure their anterior cruciate ligament (ACL) than boys. Throughout the study they looked at the reason why this injury affects mature girl athletes. The sports that have maneuvers like jumping and landing, or quick stops and turns are usually involved in the ACL injury cases. Other reasons for girls having a higher risk in ACL injuries are they tend to have larger quadriceps strength without increasing the strength of the hamstrings. This causes an imbalance on movements and increase stress on the ACL. The second reason is girl’s skeletal structure matures earlier during puberty. This makes girls have an upright position and placing stress on the ACL. More information was displayed in the article on the injury, but the conclusion shows girls have a higher risk of an ACL injury in sports due to physical growth and maturation. 2. The research article that we found talked a lot about the same issues as the journal article above. The knee joint is the second most frequently injured body part, falling behind the ankle. The research was done during 2005–2007 school years and 100 US high schools were randomly selected for a sample. Athletic trainers tracked all injuries using an online injury surveillance system. This research followed most injuries and came up with some conclusions and some insights on injuries...

...There are four ligaments within the knee joint that are influenced by knee ligament damage: the anterior, posterior, medial and lateral cruciate ligament (ACL), (PCL), (MCL) and (LCL). Complications: *Osteoarthritis, in which joint cartilage deteriorates and its smooth surface become tough. *Arthritis may happen even if you have surgery to remodel the ligament. *numbness in the front of the knee that typically requires no additional treatment. *Infection, rarely occurs about 1% of the time. *Stiffness or loss of motion happens less than fife percent of the time with modern rehabilitation techniques and rarely needs further surgical treatment. Prognosis: In case of torn ligament does not heal sufficiently, may suffer from instability in the joint, and will have higher chance to re-injury. The MCL usually responds very good to non-surgical treatment,even though surgery may be needed in rare cases. Counting on the severity of the injury, a duration of rest, bracing and physical...

Tel.: +43 512 507 4467, Fax: +43 512 507 2656, E-mail: dieter.heinrich@uibk.ac.at 1 Accepted for publication 8 August 2013 Recent data highlight that competitive skiers face a high risk of injuries especially during off-balance jump landing maneuvers in downhill skiing. The purpose of the present study was to develop a musculo-skeletal modeling and simulation approach to investigate the cause-andeffect relationship between a perturbed landing position, i.e., joint angles and trunk orientation, and the peak force in the anterior cruciate ligament (ACL) during jump landing. A two-dimensional musculo-skeletal model was developed and a baseline simulation was obtained reproducing measurement data of a reference landing movement. Based on the baseline simulation, a series of perturbed landing simulations (n = 1000) was generated. Multiple linear regression was performed to determine a relationship between peak ACL force and the perturbed landing posture. Increased backward lean, hip flexion, knee extension, and ankle dorsiflexion as well as an asymmetric position were related to higher peak ACL forces during jump landing. The orientation of the trunk of the...

...ACL Rupture in Sports PETH 197 Jacquelyn Holguin, Roy Ramirez, Audrey Beltran Seen more commonly in athletes, an injury to the anterior cruciate ligament can be a debilitating musculoskeletal injury to the knee. The most common cause of ACL injuries are Non-contact tears and ruptures. The anterior cruciate ligament (ACL) is a significant ligament for proper movement. An ACL injury causes knee instability that causes injury to other knee ligaments. Injuries of the ACL range from mild, such as small tears, to severe when the ligament is completely torn. There are several ways the ACL can be torn; the ligament tears due to it being overstretched. The movements of the knee that can result in a tear are when the knee is straightened more than 10 degrees beyond its normal maximal position. Hyperextension occurs when the lower leg is forced forward in relation to the upper leg. It can happen from a rotational injury, the knee twists when the rest of the body is moving straight. Tears in the anterior cruciate ligament often take place when the knee receives a direct impact while the leg is in a stable position, for example a standing football player is tackled sideways when his feet are firmly planted. Torn ACLs are more than often connected to high impact sports or when the knee is forced to stop suddenly at high speed and when the tibia moves forward in relation to the femur. Such types of injuries are dominant in alpine skiing, American football, basketball, rugby, professional...

...Jones of the Atlanta Braves. Chipper is famous for being one of the best switch hitters of all time, his success in the postseason, and his classy style of playing the game of baseball. He has led the Atlanta Braves franchise to 14 division championships and a World Series in the 1995 season. Ever since his rookie season in 1993, Chipper has been a fan favorite and has been a team leader for the Braves organization. Currently, Chipper is 38 and is nearing the end of his career. Throughout his career, Chipper has sustained several injuries that have plagued him as he has gotten older. This fall, Chipper was in the news a lot because of his injury he sustained during the 2010 Major League Baseball season. Chipper tore his anterior cruciate ligament and could not play the remainder of the season for the Atlanta Braves. The injury to his left knee, the impact that it had on not only himself, but also the Braves team, the Atlanta Braves franchise, and society will be discussed. This past season, in August, a groundball was hit down the third base line and Chipper fielded the ball and jumped in the air to throw the ball to first. When he landed on his left leg, he twisted his knee and fell to the ground in excruciating pain. According to the Huffington Post, in an interview after the game, Chipper said “I heard a distinct pop.” Team doctors also revealed that his knee had swollen significantly soon after the injury was sustained. According to Chapter 17 of our textbook...

...touch, and mild swelling. Third-degree burns penetrate the entire thickness of skin and permanently destroy tissue layers, resulting in skin that is dry and leathery, appearing charred or having patches which appear white, brown, or black. Remarkably third-degree burns are often painless, although pain may be caused by patches of first- and second-degree burns which often surround third-degree burns (“Types of burns”, 2012). Case Studies #2: Margie Margie, who plays center on the women’s varsity basketball tem, complains that her knee is very sore and she felt a “pop” during a scrimmage tumble. Her knee, the largest and most vul-nerable joint in her body, buckles under her weight. The ACL (anterior cruciate ligament) is part of a complicated network of tendons and ligaments that help stabilize and support the knee (Knee Injury, 2012). These structures are par-ticularly vulnerable to injury during athletic activity or as the result of impact, just as Margie ex-perienced. Giving way, or a feeling of instability of the knee, or popping or grinding in the knee is...

...want to focus on today, 19% ACL injury?! That’s quite a lot of people but if you compare it with the number of athletes that had or will had ACL injury in their whole career it’s not that spectacular if I can say, because the athletes have a number of 32% in ACL injury. An injury to the Anterior Cruciate Ligament can be a debilitating musculoskeletal injury to the knee, seen most often in athletes. Non-contact tears and ruptures are the most common causes of ACL injury. The anterior cruciate ligament (ACL) is an important ligament for proper movement. ACL injury more commonly causes knee instability that does injury to other knee ligaments. Injuries of the ACL range from mild such as small tears to severe when the ligament is completely torn. Symptoms of an ACL injury include hearing a sudden popping sound, swelling, and anterior instability of the knee (i.e. a "wobbly" feeling). Pain is also a major symptom in an ACL injury and can range from moderate to severe. Continued athletic activity on a knee with an ACL injury can have devastating consequences, resulting in massive cartilage damage, leading to an increased risk of developing osteoarthritis later in life. Other problems include anterior knee instability. ACL injury is a common cause of noncontact knee injury in football. Falls occur when the knee gives way sometimes without warning. This injury occurs when an individual stops suddenly or plants his foot really hard into the ground (cutting). ACL failure has...

Here is an article about a man with a lot of determination his name is Heston Wong he was in the Navy and started out fixing F14 aircraft and he just wasn’t fond with fixing aircraft so he was offered a store keeper job he accepted. After he finished Storekeeper “A” school he served aboard USS Santa Barbara (AE28), an ammunition ship that was home ported in Charleston, S.C. Henton on his first three-year tour, deployed two and half times, including Operation Desert Storm in 1990. Henton ran into a hiccup in 2003 aboard the USS Theodore Roosevelt (CVN71) he tore his ACL (anterior cruciate ligament) playingsoccer Heston thought that his navy career was over but it wasn’t he was reassigned to Fleet Training Center in Norfolk, Va., where he recovered for 14 months he thought about retiring in 2010 but he felt he still had a desire to serve his country. He went on to several different assignments but he said that he like the fact that when someone says, “Hey, we don’t know if we can,” I like to say, “we won’t know unless we try. Let’s try.” My source I have determined to be reliable because I retrieved the informationoff the University of Phoenix library in the section of the Scholarly (Peer review).
