ANTERIOR CRUCIATE LIGAMENT INJURY IN FOOTBALL PLAYER
ANATOMY
Palastanga (2006). Anterior cruciate ligament as two bands, anteromedial attaches anterioriorly on intercondylar eminence of medial plateau of tibia.posterolateral attach on medial aspect of lateral condyle of femur; intermediately twisted. Vascular supply is middle genicular artery.
Ekbolm (1994). In foot ball, while side cutting, players perform hip extension and abduction , knee flexion and plantar flexion, the main muscles acting is gluteus maximums for hip extension, abductor magnus, longus for abducting the hip, hamstring as knee flexors ,triceps surae and tibialis posterior as planar flexors. In kicking the ball, movement is knee flexion to knee extension and plantar flexion to dorsiflexion, movement initialised by hamstring knee flexors, and then by quadriceps for knee extension, plantar flexors and dorsiflexors.I
Bruckner(2007) In landing, the movement is hip and knee flexion, plantar flexion; the muscles acting are illiopsoas, rectus femoris, sartorious act for hip flexion, hamstrings as knee flexors, gastronemius and tibialis posterior as plantar flexors.
Cynthia Norkin (2005). In side cutting and landing, medial and lateral collateral ligament act to prevent valgus/varus stress, in contact injury this ligament resists the blow on medial or lateral aspect of knee. Meniscus, act as a shock absorber of knee.

Also adding to the joints stability are the two major pairs of ligaments: the cruciates and the collaterals. The medial and lateral collateral ligaments have a stabilizing effect in a lateral plane of motion, helping to prevent sideward displacement and over-rotation. The medial collateral attaches the femur to the tibia, also attaching to the medial meniscus. The lateral collateral attaches the femur to the fibula but has no attachment to the lateral meniscus. Both collaterals lie slightly posterior to the lateral axis of the knee joint and are taut when the knee is full extension. This positioning of the ligaments causes a slackness when flexion occurs, allowing medial and lateral rotation to take place.
There are two occurrences of ACL injuries, contact and non-contact. An ACL injury through contact
In order for athletes to save their active lifestyles they need understand the ACL. The ACL is the most important ligament in the knee because it provides stability to the knee. Athletes have to be aware of the importance of the ACL and know its functions in order to preserve the ligament. The ACL otherwise know as the anterior cruciate ligament is the ligament in the knee that connects the upper leg bone which is the femur to the lower leg bone which is the tibia. The anterior cruciate ligament crosses with the posterior cruciate ligament inside the center of the knee joint to stabilize to the knee in movement.
To understand the importance of the ACL, the knee as a whole must be examined. The knee is formed by the femur, the tibia, and the patella. Several muscles and ligaments control the motion of the knee and protect it from damage at the same time. Ligaments are dense structures of connective tissue that fasten bone to bone and stabilize the knee. Two ligaments on either side of the knee, called the medial and lateral collateral ligaments, stabilize the knee from side-to-side. The ACL along with the posterior cruciate ligament are of a pair of ligaments in the center of the knee joint that form a cross. T...

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 ...
So what causes athletes to tumble to the ground? According to the Osteoarthritis Health Center, “The knee is a vulnerable joint.” The knee is a complex system, made up of many parts that are made like delicate pieces of glass; they can easily be destroyed. The knee is formed by tendons, cartilage, ligaments, muscle, and some bone (Web MD). All of these components are sensitive pieces of the body. The Knee Pain Health Center suggests that the knee experiences wear and tear every day from a variety of activities. Sports, running, and even walking wear down the building blocks of the knee; the most common worn part is cartilage. Knees injuries are unpredictable. Aggressive actions, also suggested from the Knee Pain Health Center, includes any twisting or forceful turning. A swing of a bat, or winning tackle, puts the knee at risk for injury. Athletics that are dangerous to the knee include softball, basketball, volleyball, hockey, baseball, gymnastics, and football (Web MD).
The ACL is a ligament with an average length of 38 millimeters and a width of 11 millimeters (16). Its origin lies on the intercondylar notch of the lateral femoral condyle (the femur), runs anterior through the knee, and inserts at the anterior and medial portion of the tibial plateau (the “shin bone”) (16,18). The ACL is one of the four major ligaments contained within the knee; the others are the medial collateral ligament (MCL), the lateral collateral ligament (LCL), and the posterior collateral ligament (PCL). Each of these ligaments plays a crucial role in stabilizing the knee joint against the various movements and...
Twisting injures: Twisting injury mostly happen during cutting or pivoting motions. These Studies have revealed over 70% of these injuries happening in the noncontact situations. Landing on a flexed and externally rotated knee eccentrically loads the quadriceps, which can result in isolated anterior medial bundle tears8-9.
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.
This skill involves jumping in the sagittal plane about the transverse axis. It consists of hip, knee, ankle, and shoulder joints. In the preparation phase in propulsion, the subject has flexed knees and hips which will need to be straightened by the strength of their corresponding joints such as the hinge joint at the knee joint. The hip joint is a ball and socket joint that bears the body weight and allows for jumping motion. During th...
Two ligaments in the knees are most likely to be injured. The anterior cruciate ligament (ACL) is in the center of the knee. It is often injured by a twisting motion, such as pivoting wrong or falling awkwardly. This unfortunately is one of the ligaments that I tore. The other ligament, the medial collateral ligament (MCL) is on the inside of the knee. It is normally injured from a blow to the side of the knee. This is common in contact sports such as football and soccer. Injury to either ligament causes pain and weakens the knee joint. Without treatment, the patient may develop many other knee problems that can have lasting effects.
The problems and injuries that come with playing football have been obvious since the beginning, and to this day are still being discovered and researched in hopes of finding solutions so that the sport is not so dangerous. Malcolm Gla...
ACL injury is quite prevalent in the United States. About every 1 in 3,000 people suffer from an ACL injury in their lifetime, and approximately 95,000 new incidences of ACL injury occur each year. The largest amount of these injuries occurs during sports which involve twisting, cutting, jumping and deceleration. The mechanisms that can cause an ACL injury are excessive valgus (outside of knee) stress, forced hyperextension, or forced external rotation of the femur on the a fixed tibia (Evans, 2001). Many associate the tearing of the ACL with a large impact or collision, however 80% of all ACL injuries are non-contact injuries. This statistic shows that ACL injuries are mostly caused by the individual themselves as opposed to an opponent or other person. The exact mechanism of noncontact ACL tears consists of poor knee positioning (e.g. landing with an extended knee) and a strong, unopposed quad contraction (Murray, 2013).
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
