Understanding the cause of sports injury requires a precise description of the injury mechanism. Over two million anterior cruciate ligament (ACL) injuries occur worldwide annually, and the greater prevalence for ACL injury in young female athletes is one of the major problems in sports medicine. The most common gender differences are reduced knee and hip flexion when landing, increased knee valgus, internal rotation of the femur and high quadriceps activity unbalanced by the hamstrings in female athletes (Renstrom 2013). The female ACL is smaller in length, cross-sectional area, and volume than the male ACL, even after adjusting for body anthropometry (Shultz 2010). The mechanical and molecular properties of the ACL are likely influenced not only by estrogen but also by the interaction of several sex hormones, secondary messengers, remodeling proteins, and mechanical stresses (Shultz 2010).

1.1 Overview Of Knee Injury Knee organ is the largest joint in the human body, specifically in the leg and it is the easiest part of the body to be injured. Knee injuries can be caused by a sudden injury, an overused injury or by an underlying condition. The treatment depends on the cause and type of injury. Early symptoms of knee injury can include pain, swelling, and stiffness. Most people have had a minor knee problem at one time or another.
Strains – strains occur as a result of a partial or a complete muscle tear. Tendonitis – this condition occurs as a result of irritation or inflammation of the tendon. Meniscus tears – this is one of the most common knee injuries in football, as it occurs due to the sudden changes in speed or the sudden side-to-side movements. Bursitis – this condition occurs as a result of irritation or swelling of the knee
The ACL crosses diagonally in the middle of the knee behind the patella and it connects the tibia to the femur. Its function is to prevent the tibia from sliding in front of the femur and to prevent overextension of the knee. The LCL connects the femur to the fibula and its function is to keep the lateral side of the knee stable. RG3’s injury is due to an ACL and LCL tear. The ACL was torn when his foot planted in the field and his knee cut into internal rotation.
Anterior Cruciate Ligament The ACL is a ligament in the outer leg next to the knee. Most anterior cruciate ligament tears require surgery, unless the orthopedic surgeon says otherwise. An ACL tear is the most common injury and in the knee. These injuries are happening more frequently in teenagers now. The ACL can be strengthened to help prevent it from tearing.
Another way to put it, is Mechanics of Movement. Although ACL tears in women’s sports happen more likely in contact sports (soccer and basketball) seventy percent of all ACL injuries are from non contact. Non contact ACL injuries happen because of the pressure applied to the knee due to the movement that the athletes made (Olmstead). The movement that cause ACL injuries are pivoting, jumping, landing, and sudden change of direction. Sports such as soccer and basketball that include those movements are the highest at risk for ACL injuries (“Why do Females
ACL Tears and Replacements In the United States there is between 100,000 and 200,000 ACL tears a year (anterior). This number may be more but due to the limited data since if you do tear your ACL you do not have to register nothing so if you don't register that you tore your ACL then the number does not go up. Most ACL injuries come from non contact sports or athletics. Surgery is highly recommended for ACL tears.
Torn knee ligament Causes: Torn knee ligament occurs when at least one of the main ligaments inside the knee gets sprained and the condition gets to harsher so the ligament ruptures. Basically, there are four main ligaments; Medial collateral ligament(MCL), Lateral collateral ligament(LCL), Anterior cruciate ligament(ACL) and Posterior cruciate ligament(PCL). All these ligaments have different functions. - MCL is located between femur and tibia. It helps protect the knee joint from the outer side forces, and it controls the amount of movement of knee.
From 2010 to 2013 players in the NFL suffered 219 ACL tears. That is a very high number for only ACL tears. There is many other knee injuries that are possible to happen. People need to make sure they don’t go back to sports too early after the injury. The risk of reinjury is a lot higher if you return to early.
Athletes Closest Thing to Death Former MVP in the NBA, Derrick Rose, jumps his into the air to contest a shot. He comes down hard and collapses on the gym court as the crowd watches the NBA’s finest point guard suffering in agony they are all quiet waiting for him to hop up and continue to play. Unfortunately that 's not the case, and never is with a torn ligament. He was escorted off the court and sent to the hospital where his career fell off a cliff and he has never been even close to as good as he was before his injury. Ligament tears in the knee are one of the worst sports injuries to obtain when as an athlete because they can never go back to how the ligament was to begin with.
Surgical MCL Repair vs. Non-Surgical Kirk J. Hillstrom, Physical Therapist Assistant Student Finlandia University Surgical MCL Repair vs. Non-Surgical With the rising popularity of sports; hockey, football, and, skiing, the Medial Cruciate Ligament of the knee, is the top-rated injury of the ligaments in the knee. It doesn’t necessarily have to include sports, but rather focuses on the valgus stress or force to the knee. A valgus force is blow with a severe force to the lateral portion of the knee, and is paired with the term sprain. The MCL constricts abduction of the knee, and constricts external rotation of the tibia on the femur.
These knee injuries can affect a player's long term involvement in the sport. Football players also have a much higher chance of ankle sprains due to the surfaces of the fields they play on and cutting motions. Shoulder injuries are also common and the labrum (cartilage bumper surrounding the socket part of the shoulder) is particularly susceptible to injury, especially in offensive and defensive linemen. In addition, injuries to the acromioclavicular joint (ACJ) or shoulder are seen in football players. Football players are very susceptible to receiving concussions.
The 20 athletes were comprised of 17 men and 3 women ranging from the ages of 18-30 years old (Christakou, Zervas, & Lavallee, 2007). The sports in which the ankle injuries occurred were volleyball, basketball, mini-soccer, long jump, gymnastics, and judo. The 20 athletes were then divided in to two groups at random consisting of the control and the experimental group. In the control group there were nine men and one woman.
