Anterior Cruciate Ligament
With an ever increasing number of people becoming involved with athletic activities, there is an increasing number of injuries occurring which can be devastating for the individual. Most of the injuries that affect athletes occur in one of four structures in the human body: bones, muscles, tendons, or ligaments. Because ligaments attach bone to bone and play a major part in providing stability for joints, the major stabilizing ligament in the knee, the anterior cruciate ligament (ACL), assists in performing everyday actions of the human body including sitting, standing, walking, running, dancing, and participating in other sports. The injury that specifically affects this ligament is very serious and always provides a challenge for the health care provider, in most cases the orthopedic doctor, who is responsible for the correction of the problem. By understanding how to diagnose one of the most common sports injuries, an anterior cruciate ligament (ACL) tear, realizing the causes, and providing the proper treatment, an orthopedic doctor can help a patient minimize his or her risk of experiencing long-term problems that may be associated with this injury.
In order for an orthopedic doctor to diagnose an ACL injury, he or she must first be knowledgeable about the ligament's location and function. The anterior cruciate ligament is located directly in the center of the knee along with another critical ligament known as the posterior cruciate ligament.
The two ligaments cross each other to form an “X” behind the kneecap to provide the most support for the knee joint, where most of a person's body weight is concentrated. Although the ACL, which connects the thighbone (femur) to the shinbone (tib...

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 spite of this the rate of ACL injury is almost equal through all levels of sports, from beginner, to recreational, to professional athletes. The most widely publicized incident of ACL damage has come from Theresa Edwards who was a top female athlete. She was a basketball player who went to the limit with sports. She went beyond her capability and her ligament couldn’t withstand the pressure and snapped. She is not the only but just one example of many who have suffered this same problem. As female athletes continue to become more competitive and aggressive, ACL damage continues to rise.

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.

There are many injuries in general, but sports injuries? Sprains and Strains are the most common injuries in sports. “Sprains are injuries to ligaments, the tough bands connecting in a joint. Suddenly stretching ligaments past their limits deforms or tears them” (Hoffman 1). Ligaments are like springs in a sense that when you stretch a spring, it will return to it’s normal state unless they are
Kurt Vonnegut was a socialist, many would assume this dream falls in with his beliefs. However, “Too often, [Vonnegut] warns, people assume that equality means being the same. This is simply not realistic (Labin).” Vonnegut did not believe in equality, rather he favored equal opportunity. For this reason he shows us a possible future society in which, “Nobody was smarter than anybody else. Nobody was better looking than anybody else. Nobody was stronger or quicker than anybody else.” (232 Vonnegut). And this is why there are two distinct classes, average citizens with handicaps and above average citizens without handicaps. Additionally, there are two more less obvious classes, the below average citizens and the agents of the handicap ge...

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.

Hence production units for example the exports that take place in Europe and its Ukraine therefore they have competitive advantage with value into the technology. It gone through the acquisition by natural resource seeking for example Tata Company has invested in coal mines in different country and ownership advantage the company that enables them to successfully acquire established goal companies (KUMAR, 2008).Location advantage of Tata motors has the nature of the product and the services which the company requires to invest In plant or an office (Neelankavil and Rai,2009).In addition the Tata Company has a manufacturing with joint venture and Thornburg automotive gives which them a location advantage again in the south East Asia region. Internationalization advantage of Tata motors will help them in having better control over the manufacturing units as licensing option which are issues related to transfer of technology or technology theft. The advantages of own production for Tata company which they have done is introducing a new car called Nano an ultra low cost car
As Tata Motors is an automobile company, the raw materials required in production of a car or a vehicle include aluminium, copper, platinum, palladium, rhodium, steel and zinc. The prices for these materials have been increasing in the recent years. An increase in price of input materials could severely impact its profitability. Additionally, increases in fuel costs also pose a significant challenge to automobile manufacturers worldwide, especially in the commercial and premium vehicle segments where increased fuel prices have an impact on
