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

This short and round ligament, like all other ligaments, prevents slippage within the joint and allows the joint to properly pivot when performing an action (Duff 300). Without this particular ligament, the knees would be fragile and more susceptible to injury. Therefore, it would be impossible to do the simplest movements that are done by humans everyday, like walking and even sitting. This is one reason why many athletes should be aware of the physical indications that arise if they have torn their ACL while participating in athletic activities.
In many cases, the symptoms that the patient feels after the trauma has occurred can help the doctor make his or her diagnosis. Many times a doctor will ask the patient to recall what happened after the injury was sustained. Usually with an ACL injury, the patient will describe a so-called pop or snap that he or she heard during the impact. Pain, which is not terribly excruciating, will immediately follow, and if the individual tries to stand, he or she will be faced with an overwhelming feeling of instability, the leg will buckle under, and the individual will ultimately fall down onto the ground. Although the patient is experiencing pain, he or she cannot point out exactly where the injury has occurred. Garrick states, “some people say that their knee shifts in position – which it actually does” (118). Other symptoms that may arise are stiffness and swelling which may continue for a long
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.
ACL (Anterior Cruciate Ligament) tears relates back to Egyptian era. Back then, they first started by trying to stitch the ACL back together where it tore, that’s how surgeons learned about grafting. Starting off, the hamstring was the first thing they tried using this new technique on. After success with the hamstring graft, they moved to trying the patellar tendon graft, which was also successful. Fortunately, surgeons now have many ways to repair ACL
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)
There are many important parts in your body, and the anterior cruciate ligament(ACL) is one of the most important part to your leg and fitness. The ACL gives the knee its stability and many injuries can happen to this part of the body, so people with these injuries often visit rehabilitation(rehab) therapy for faster recovery. This is one of the most common athletic injuries. Mostly teens, who play sports, get these injuries. A pop usually indicates that the ACL is torn. Many people come to rehab therapy, and even with this special treatment, it takes a very long time for full restoration. The torn ACL not only affects certain parts of your body, but also affects several parts that can cause more severe injuries.
Anterior cruciate ligament injury is a common injury, especially among athletes. There are several factors that contribute to the likelihood of ACL rupture. These factors can be genetic, environmental, structural, and behavioral. Reconstruction is the best option for those wishing to be able to participate in physical activity again. The autograft, a graft taken from the individual, is the most common choice. The graft can be taken from the patellar bone or the hamstring tendon. Each graft has distinct advantages and disadvantages. ACLR also has physical effects including knee pain, decrease in athletic ability at high intensity levels, and osteoarthritis.
The Anterior Cruciate Ligament (ACL) is one of the most common knee injuries in female sports today. The ACL is a ligament that attaches the femur and tibia to the knee allowing the knee to bend while still being stable and supporting the whole body. Dr. Russel F. Warren, a physician for the New York Giants football team, explains, “The ACL prevents the shin bone (tibia) from moving too far forward on the thigh bone (femur) and keeps the knee from twisting inward excessively.” When athletes tear their ACL there is a greater chance that they have hurt or another ligament in their knee such as the LCL, MCL or Meniscus; which is cartilage that absorbs shock from the body’s pressure (MedlinePlus). The ACL is strong, but one wrong move could result
The ACL (anterior cruciate ligament) prevents anterior forward movement of the tibia off of the femur, as well as hyperextension of the knee. It provides stability to the joint and allows for a dynamic motion. It also helps the bending of the knee sideways toward the body.
The ACL (anterior cruciate ligament) is one of four ligaments to connect the thigh bone to the shin bone. The ACL stabilize the knee, controls excessive movement, and limits joint mobility. The ACL is primarily for the forward motion when walking, running, and jumping. Without the ACL the thighbone would constantly dislocate from the shin bone.
All high school I have seen this injury happen to several athletes affecting their performance. Usually from what I have noticed this disability, although temporary, can ruin an athlete’s opportunity to continue in the sport thus making them lose several opportunities. The disability I am speaking of is an ACL tear. “A torn anterior cruciate ligament (ACL) is a common knee injury, especially for athletes. Ligaments are long, rope-like bands that fasten bones together. The ACL’s role is that it helps give the knee its stability. This injury usually occurs through movements such as pivoting, stopping, or turning on a dime. People also can also receive this injury if they jump up and when they are on their way down their knee is locked instead of flexed. This puts pressure on the knee joint and causes the ACL to tear or break apart”(Jr. A.). ACL injuries are quite often in sports I was privileged to interview someone who has experienced it on a
Injury of the ACL is now the most common ligamentous injury of the knee and accounts for about 30 injuries per 100,000 of the population (Irrgang, 1996). Over time it became apparent that multiple variables act in combination to influence ACL injury risk(Wojtys, 2003). Risk
The anterior cruciate ligament is a stabilizing force within the knee joint. The ACL prevents hyperextension as well as limiting excessive tibial rotation and valgus/varus stresses of the knee joint. Athletes are expected to perform maneuvers that put excessive force on their knees. An ACL tear is a common injury among athletes resulting in the need for surgical intervention. After surgery and physical therapy, the goal usually included to return to sports at their prior level of competition while trying to prevent reinjury. What criteria do clinicians use to determine when the athlete is ready? Several studies were reviewed to answer this question. The results included several variables that could predispose an athlete to reinjury, several
The ACL’s main function is to stabilize the knee and to provide proprioceptive feedback to the brain. The ACL stabilizes the ligaments of the knee during dynamic movement by keeping the tibia from sliding forward relative to the femur; while also restricting excessive knee extension, and preventing twisting of the knee inwards and outwards (Amis & Dawkins as cited in Dharamsi & Labella, 2013, p. 12; Silvers, 2009, p.81). The ACL acts to protect the cartilaginous shock absorbers of the knee, which are the menisci, from damage that may result from playing sports (Dharamsi & Labella, 2013 p.
A torn ACL is one of the most serious and common knee injuries. Many aspects play a role in the treatment and rehabilitation of this injury. This paper will discuss the anatomy of the knee, describe a torn ACL, and the rehabilitation.
ACL injuries are very common and one of the most discussed injuries in sports. Athletes who may have had a history of an ATSF during their childhood should be aware that they are more prone to an ACL injury in the near future. By conducting research such as this one, it allows athletes/patients to become more aware with their follow-ups and to be more careful when playing their sports. As Exercise Scientists, we overlook the way the body moves. So, if we
This essay deals with the current treatments, rehabilitation procedures and onsets following anterior cruciate ligament (ACL) injuries. Within this essay, there will be information including the causes, characteristics, and symptoms of ACL injuries. Throughout the United States, there are estimated to be 200,000 ACL injuries per year with 100,000 of those injuries being treated through ACL reconstruction (Evans, Shaginaw, & Bartolozz, 2014). With a satisfactory ACL reconstruction outcome between 75%-97%. From the 10%-15% failure rate of ACL reconstruction, the primary fault is due to technical mistakes at 70% (Samitier, Marcano, Alentorn-Geli, Cugot, Former, & Moser,
