An Anterior Cruciate Ligament ( Acl ) Injury

The ACL is the Anterior Cruciate Ligament is in the front of the knee and serves a few purposes such as being in control of the knee twisting and keeps the tibia from going over the femur, and keeps the knee from hyperextending.

An anterior cruciate ligament (ACL) injury is the overstretching or tearing of the in the knee. This muscle is located just below the knee bone and the tear that occurs may be partial or complete. When you hear your ACL pop that’s a clear sign of a tear. Lots of people have surgery to get it repaired. It is about a year recovery of rehab. Many times when you tear your ACL, there’s no

Each year, approximately a quarter of a million physically active young people experience an anterior cruciate ligament (ACL) injury, and seventy percent of these ACL injuries will be sustained while engaging in non-contact activities such as sudden deceleration while landing (Begalle et al., 2012). This type of injury is grossly detrimental not only on the occasion in which it occurs but also for the subsequent years to come. The majority of individuals who injure their ACL also go on to either, re-injure that same ACL, or injure the opposite knee. Furthermore, our bodies are put in tremendously vulnerable planes of motion during sporting events, especially during activities such as, basketball, football, or soccer. In this day

First and foremost, your knee has four ligaments. The ligaments line up your bones and help control the way you move. It prevents the shins from moving too far forward. ACL injuries sometimes requires surgery.

The anterior cruciate ligament (ACL) has limited range of motion, which leads to it being the most frequently injured ligament singularly (Ireland, 1999). This study was conducted to present the epidemiology on ACL injuries in female athletes (Ireland, 1999). Epidemiology is the part of science that focuses on the causes, effects, and patterns of disease and health conditions that occur in specific populations. The epidemiology in this article focuses on female athletes that have had a noncontact ACL injury playing either basketball or soccer (Ireland, 1999).

The Anterior Cruciate Ligament (ACL) and the Posterior Cruciate Ligament (PCL) are located inside the knee joint. The ACL and PCL form an ‘X’ behind the kneecap (patella), with the ACL resting in front of the PCL. Both of these ligaments are responsible for controlling the back and forth motion of the knee joint; however, the ACL is responsible for stabilizing the kneecap ). In addition, the ACL is responsible for preventing the shin bone (tibia) from sliding forward on the thigh bone (femur). The ACL provides the knee with stability while an individual pivots or twists. This ligament is critical because without it, performing any kind of rotational activity is impossible, particularly when it comes to playing sports like soccer and basketball.

There have been many studies done to explain the higher rate of ACL injury in female athletes. The most convincing findings relate to knee kinematics and neuromuscular control. In a study of 20 subjects (10 male and 10 female) forces from jump tasks were recorded using 3-D videography and force plates. One conclusion from the study was that force on the ACL was greatest during the landing phase of a jump tasks. Females frequently showed more leg extension and valgus movements during the landing phase, which also puts more stress on the ACL (Chappel et all, 2002). A similar study found that internal rotation combined with valgus movement creates

Whenever an athlete participates in a sport, whether it be practice or a meet/game, they run the risk of injuring themselves. When it comes to basketball, Anterior Cruciate Ligament (ACL) injuries are common. ACL tears are more likely to occur in female basketball players as opposed to males. In basketball, speed, strength, and power are the most important physical qualities to develop. Sometimes an athlete may be lacking in certain areas which puts them at a greater risk for tearing their ACL.

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

The ACL originates from the medial and anterior aspect of the tibial plateau and runs superiorly, laterally, and posteriorly toward its insertion on the lateral femoral condyle. Together with the posterior cruciate ligament (PCL), the ACL guides the instantaneous center of rotation of the knee, therefore controlling joint kinematics. To a lesser degree, the ACL checks extension and hyperextension. The ACL is not as strong as the posterior cruciate ligament (PCL), and it is less strong at its femoral origin than at its tibial insertion. Muscles surrounding the knee joint contribute to knee stabilization during lower extremity movements.

A torn ACL is a injury in which also is a torn anterior cruciate ligament in the knee. When someone tears their ACL they have to have a surgery to replace it. ACL injuries range from mild, such as a small tear, to severe such as when the ligament tears completely or when the ligament and part of the bone separate from the rest of the bone. A lot of the time some of the other knee ligaments or parts of the knee are also injured. This includes cartilage such as the menisci, or bones in the knee joint they also can be broken. Your ACL can be broken during sport activities. During an activity if your leg is planted firmly on the ground then hit by a heavy/large force it could tear the ACL. Some ways your ACL can be tore is by being bent backwards,

The Anterior Cruciate Ligament also known as the ACL is deemed the most commonly torn ligament in the knee and can result from both contact and noncontact injuries. Most Anterior Cruciate Ligament injuries result from an extreme force on the lateral side of the person’s knee causing a valgus force which pushes the knee inward (Kisner & Colby, 2012, pp. 802-803). This injury to the side of the knee can also cause a “Terrible Triad” injury which also injures both the medial meniscus and the medial collateral ligament (Kisner & Colby, 2012, p. 803). Our textbook further states that “the most common noncontact mechanism is a rotational mechanism in which the tibia is externally rotated on the planted foot….this mechanism can account for as many as 78% of all ACL injuries” (Kisner & Colby, 2012, p. 803). If the person does not seek medical help with this injury they are susceptible to also injuring the remaining support ligaments as well. Patients usually present with joint effusion; possibly 25 degrees of flexion, joint swelling if blood vessels are involved, limited ROM, stress pain and instability along with quads avoidance gait patterns (Kisner & Colby, 2011, p. 208)

In the sports world the word ACL brings absolute horror and cringe with it. That’s because when an ACL tears it can be one of the most painful experiences an athlete can have, especially with the surgeries and recovery it brings with it. Along with that, the ACL is in the deep part of the middle of the knee, so most of the time when you damage your ACL you most likely have damaged something else. Women especially have to worry about the overall health of their knees as they have a 4.8% greater chance of tearing their ACL than men (Musgrave). ACL tears are one of the worst injuries in the sports world and in order to recover to full health it takes time, patience, and a hard-work ethic.

The two treatment modalities were early surgical treatment with rehabilitation, and aggressive early rehabilitation; with the option for later surgery if needed. This compares the major differences in thought on treatment of anterior cruciate ligament injuries between surgical and non-surgical. (Frobell, Roos, Roos, Ranstan, & Lohmander, 2010)

The knee joint consists of four ligaments, two intra-capsular which are the ACL and the PCL and two extra-capsular ligaments including the MCL and LCL. The ACL is an extremely strong stabiliser which prevents anterior displacement of the knee. The ACL is a ligament and therefore connects one bone to another, the femur with the tibia. The ACLs origin is from the anterior intercondylar eminence of the tibia (home,2017) and the fibres pass upwards, backward and laterally inserting into the lateral condyle of the femur.
