Acl Injuries In Athletes ACL Injuries in Athletes 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. The anterior cruciate ligament is the reason that the knee only has one pattern of movement. Instead of moving sideways and up and down, the knee only serves as a pivot for flexion (bending) and extension (straightening); it holds the tibia and femur in place (northstar). In the northstar web page it is stated that, ?The anterior cruciate ligament is one of the most important ligaments to athletes because of its main function, stabilization of the joint while decelerating.? In other words, it is the reason that we can stop abruptly without our leg collapsing. Obviously this asset makes it an essential to have a functioning ACL while playing sports. It is an especially common injury in soccer, which is a game of constant abrupt stops. Not only is soccer a danger to the ACL because of its constant stops and starts, it is also a game of jumps, falls, and slide-tackles, which put a continuous stress on the ACL for the entire 90 minutes of the game. ACL tears are also more common in women . It is said that the reason for this is because women's bodies were not meant for playing intense sports, and are therefore more likely to endure such injuries. The ACL is the most frequently injured part of the knee when related to sports. As fore-mentioned, the ACL aids us in abrupt stops; it are these abrupt stops that are the most common cause for its injury. ( Figure 1. shows the difference between a normal ACL and a torn one.) An ACL injury has not been scientifically proven to be linked to weight, size, or strength (Duff 308). The cause can be a violent twist of the knee, or it can simply be caused by standing up too fast. It can be twisted or hyper extended. In any case, if it is concluded that the ACL has been ruptured, the symptoms and treatment remain the same. In any injury tiny, or large, blood vessels are broken, resulting in bleeding into the area of the injury. This is the cause of swelling. In an ACL tear, the knee swells almost immediately because of the broken blood vessels in the ligament ( Sechrest.com). The initial tear makes a loud ?pop? and, because of the absence of the ligament's reinforcement, there is a feeling of instability in the knee. In some cases, the knee actually subluxes, which is a dislocation that pops back into place on its own. In these cases, there is usually more injured than just the ACL. Often the MCL (medial collateral ligament) is also injured (Sechrest.com). Other common symptoms, according to the northstar website are pain and the athlete falling to the ground as a result of the instability, or buckling, of the knee. A torn ACL can only truly be determined through a series of tests starting with a physical examination, as in the Lachman's and Anterior Drawer tests. In the Lachman's test (shown in Fig. 2.), ?[the] Patient with suspected injury lies supine on examination table and flexes the knee at 15 degrees. The person examining the patient stands on the affected side of the extremity and holds the patient's femur (thigh) immobile with one hand. The other hand is placed

All members seem much concerned regarding the topic in play. None of them is dormant and each seems to have a point to contribute. One of the group members, a lady actually, interrupts her friends and she does not seem to agree with any of the members. She frequently gestures when explaining her point of view. Apparently the other members seem to appreciate her and each time her turn to talk to talk is over, they clap and laugh before one of the members complements the ladys sentiments. One of the members, a middle aged man is heard rebuking some evil spirits giving an example of another man who had been prayed for by the pastor. Any time the man talks, all other members listen keenly and they seem serious while their eyes are glued on the mans face. After a thirty minutes discussion, the group moves under a tree shade may be to hide from the scorch sun. They now seem comfortable with their new position. It is now much easier to hear what the discussion entails as the place is a bit raised. It is now pparent that the man was talking of a man believed to be possessed by evil spirits. He explains of how the pastor noted it and he called the man for a prayer session. At this point the man explains with much vigor to a point he opens wide his eyes. He talks of how this world is full of evil and no wonder most of the people have been indulging in evil doing and worshipping idols hence being possessed by evil spirits. The others uniformly raise their arms and rebuke while mentioning the devil. The lady who was fond interrupting herb friends now seems acceptable and she agrees on whatever the man says. Actually she is very supportive of the current topic and she even talks of how, many people condone devils works unknowingly and ultimat ely becoming devils followers. Lady 1: I think its time most of these people opened up their minds and learn the tricks by the destroyer. Its quite hard to note how the devil operates so the best thing is to get prepared my dear brethren. Lady 2: Exactly. Just look at him (she points at the direction they have come from and where the church is built. Though she never mentions annyone, the rest of the group seems to agree with her and they are quite aware that the lady is talking of the particular man the pastor prayed for). He would have been totally exploited by the devil but God always intervenes. Man 1: Actually what we ought to comprehend is that the devil is there to sooth no one. Not unless we become stronger in faith and much conscious regarding what is happening, am certain that the world will have to remain desperate as the devil is a liar, he came to steal, kill and then destroy. Let strengthen our faith in Christ. (The others in a chorus say Amen). Man 2. Otherwise God is good. (The others complement all the time). Seemingly all the members agree with one another and seem to share many feelings regarding any topic in play. They all back one anothers point of view and they really have a lot to share. This makes one conclude that these are members of the same church whereby they are attempting to strengthen one anothers faith through encouraging their fellow church mates. At the end the group disperses and only two of the members move in the same direction. Buy custom Field Research essay
