INTRODUCTION:
Anterior cruciate ligament (ACL) injuries are a major problem seen in many sports. It has been estimated in USA there is approximately 175, 00 primary ACL reconstruction surgeries performed annually, with the cost being estimated to be over US $2 billion1. After having a complete ACL rupture, many other knee problems such as chronic knee instability can occur. ACL injuries continue to remain the largest single problem in orthopaedic sports medicine, especially in young female athletes aged 14-19 years, producing the need to improve prevention and management2.
Non-contact ACL injuries are the most prevalent in sports. Most non-contact ACL injuries occur when the person is generating more force or moments at the knee that is causing excessive loading of the ACL. Excessive loading can result due to a sudden deceleration, landing and pivoting manoeuvres being performed over and over1. R Dick has reported that female athletes who perform the task that increase the risk are at a higher risk of ACL injuries than males. His study showed that females are two to eight times more likely to have a non-contact ACL injury3. This could be due to females having a smaller knee flexion angle during sporting activates. Studies have shown that after the age of 13 years females knee flexion angle decrease during a stop-jump task. These results show that females older than 13 years have an increased change of sustaining a non-contact ACL injury3.
Current literature has shown that the sagittal plane biomechanics factors such as greater posterior ground reaction force, small knee flexion angle and greater quadriceps muscle force play a major role in ACL loading. G Li study showed that ACL loading increase as the knee flexion angle de...

CONCLUSION:
The data collected from this study has help identify if there is a difference in genders when it comes to ACL injuries. The finds showed that females are more proven to an ACL injury when compared to men. This has been backed up by analysing data from the force plates and using the LESS scoring system.
As a results of the many non-contact ACL injury studies that have been done, many practical applications can be applied. The main practical application that has come out of these studies is the ability to be able prevent non-contact ACL injuries.
To future look into ACL injuries in males and females, there needs to be studies done to look at gender difference in sport. There studies should involve a variety of sporting action, not just jumping, and assess the impact on the ACL ligament.

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 “...
Tearing the ACL is now considered an epidemic in the United States over 100,000 recorded incidences are reported each year (Moeller). While such a finding may be good for orthopedic doctors and surgeons, this is not good for millions of athletes’ competing these days in high intensity sports. This is especially a problem for female athletes who are two to four times more likely to tear their ACL than men (Moeller). This is one of the biggest mysteries about ACL tears is the difference between the number of injuries seen in women and men. Women tend to tear there ACL far more frequently then men. While not everyone agrees that gender itself is the source of the problem, evidence is growing that females are learning too late that participating in sports can also become the first step to ruining an active lifestyle.
The most common knee injury in sports is damage to the anterior cruciate ligament (ACL) through tears or sprains. “They occur in high demand sports that involve planting and cutting, jumping with a poor landing, and stopping immediately or changing directions” (University of Colorado Hospital). The ACL is a ligament that runs diagonally in the middle of the knee and found at the front of the patellar bone. Its function involves controlling the back and forth motion of the knee, preventing the tibia from sliding out in front of the femur, and providing rational stability to the knee. Interestingly, women are more prone to ACL injuries than men. The occurrence is four to six times greater in female athletes.
Al Toon, father of Saints receiver Nick Toon, was forced to leave professional football after sustaining nine concussions in eight years of professional football. Football is one of the most dangerous games. As the years go on, more and more rules are being written to prevent the danger, but danger is the nature of the game. Most of these rules are for the protection of the players, but there are times when injuries can be a good thing. The Philadelphia Eagles were 3-5 to start the year, but Michael Vick was injured and the backup quarterback led the team to be 10-6, win the division, and almost beat the New Orleans Saints in the playoffs. "About 1.7 million Americans suffer a traumatic brain injury (TBI) every year, about three-quarters of them mild TBIs, or concussions" (Clemmitt). Traumatic Brain Injuries are used as the main form of evidence in Richard Cohen's claim that the end of the NFL is near, and quite frankly, his argument is pretty solid.
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.
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.
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
The majority of ACL injuries suffered during athletic participation are of the noncontact variety. Three main noncontact mechanisms have been identified planting and cutting, straight-knee landing and one-step stop landing with the knee hyperextended. Pivoting and sudden deceleration are also common mechanisms of noncontact ACL injury. Basketball, soccer, and volleyball consistently produce some of the highest ACL injury rates across various age groups. Other activities with a high rate of injury are gymnastics, martial arts, and running. In most sports, injuries occur more often in games than in practice. Many injuries have occurred during the first 30 minutes of play. One-reason physicians are seeing more ACL injuries in female patients that more women play sports, and they play more intensely. But as they continued to do more studies, they are finding that women's higher rate of ACL is probably due ...

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.
Also, it was stated that because of the elbow angle at foot stride and ball release that the shoulder joint was affected more so than at any other time. Finally, in order to understand why the injuries occur we should learn the joint ranges of motion so we can develop better preventive methods for injuries.

The purpose of the squat is to train the muscles around the knees and hip joints, as well as to develop strength in the lower back, for execution of basic skills required in many sporting events and activities of daily living. Because a strong and stable knee is extremely important to an athlete or patient’s success, an understanding of knee biomechanics while performing the squat is helpful to therapists, trainers, and athletes alike (11). Because most activities of daily living require the coordinated contraction of several muscle groups at once, and squatting (a multi-joint movement) is one of the few strength training exercises that is able to effectively recruit multiple muscle groups in a single movement, squats are considered one of the most functional and efficient weight-bearing exercises whether an individual’s goals are sport specific or are for an increased quality of life
