A Torn Anterior Cruciate Ligament Analysis

Sports are great to keep you in shape and to have fun but there is also a heavy risk of getting injured. Injuries such as pulling a hamstring or breaking an arm can lead to many complications. There are 2 injuries that are pretty common but they are some of the worst injuries. That is an ACL tear and a concussion.

In recent years is has become one of the most rehabilitated ligament is in the body right up there with the bicep tendon. Over the past few years anterior cruciate ligament injuries have increased and are spreading across different age and gender lines. Most of the ACL injuries that we see can be classified as a contact injury. I use a contact injury here to mean that two people or even a person and an object, such as a ball, collide with a massive force and cause the movement of the knee in a way that tears the ligament. An example of this would be when two soccer players collide as they are going for the ball and the force of player one hits player two on the back of the knee causing the tibia to move in that anterior motion further than the limits of the anterior cruciate ligament and causing the tear. The fix for this is through surgery known and an ACL Reconstruction.

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 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)

Non-contact ACL tears are more common in sports that require jumping and pivoting. (Washington, 2009, pg. 1)

Female athletes can protect themselves through many stretches and prevention programs provided by their coaches, parents and Athletic Trainers. Many ACL tears can be protected by warm- up or cool-down programs or stretching (Ritter). The solution to preventing some of the ACL injuries is a strength and flexibility programs to strengthen the hamstrings, quadriceps and the core while stabilizing the knee (Busse). Working on the athlete’s techniques such as running, jumping and landing techniques can vastly improve their chances of ACL strength and would help prevent against tears (Malamut). Using an ACL prevention program teaches athletes how to align their hips for correct form and how to jump correctly without pain and without being knock-knee.

the knee that can be felt. Because of this and the PCL, the knee stays attached, stable, and functional. But when the ACL is injured in the form of a tear the knee has limited function until the tear is fixed, and even then many female athletes still have problems with their knees throughout the rest of their athletic career because the ACL may not recover 100% of its function and stability. Without reconstruction surgery, everyday tasks such as walking are still possible but for high performance athletes, the torn ACL cannot endure the stress placed on the knee.

In the final analysis, ACL tears are more commonly found in females because of the anatomical structure of women, improper body mechanics, and the differences in female’s circulating hormones. The human female structure has many differences to the male structure, such as muscle stiffness, stronger quadriceps than hamstrings, a wider pelvis bone, and smaller intercondylar notches. These differences in male and female structure can lead to why ACL tears are more frequent in females. Another reason as to why females are more prone to knee ligament tears is because of of the improper body mechanics performed by women. During sports, contact or noncontact studies show that women perform cutting movements that are more erect rather than a crouched

The Anterior Cruciate Ligament, also known as the ACL, plays an important role in the stabilization of the knee. The ACL connects the femur to the tibia. The ACL passes, in a diagonal, from the outer area of the femur to the inner area of the tibia. The main function of the ACL is to restrain forward movement and the inner rotation of the bottom half of the leg, as well as prevent hyperextension of the knee (Schwager, 2009).

The act of suddenly stopping and changing directions or a hard impact to the side of the knee can cause a strain or tear of the ACL. These are one of the most severe sports injuries, but not the most common. A completely torn ligament requires surgery and may cut an athletic career short. If you think you might have an ACL injury, see your doctor immediately.

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

A common injury among athletes is to tear their anterior cruciate ligament (ACL). People who tear their ACL’s need to have surgery in order to help them recover and have no long term effects. The surgery consists of implanting an Endo button to keep their knee in place while the body heals itself. For this project an endo button was designed with specific dimensions taking in consideration the maximum forces that will be acting on the button. Ten materials were analyzed and one material was chosen based on the analysis. The material has to be able to withstand the forces, be as small as possible, and not be hazardous to the patient. This report will explain the procedures and methods that were used in order to choose the material.

: One of the most common ligamentous injuries of the knee is to the anterior cruciate ligament. Early recognition of the pathology is critical when determining the most appropriate course of care to optimize potential outcomes. The Lachman’s test is characterized by clinicians as the most direct and definitive evaluative tool used in determining the status of ACL injuries, because of its sensitivity, specificity and likelihood ratios. However most clinicians also assign a categorical grade to describe the end feel of the tibial translation, yet the reliability, accuracy, and clinical utility of this assessment has not been subjected to critical

One of the major of concerns among sport teams, coaches and athletes is injury. Numerous injuries occur each year caused by sport, resulting in decreased physical activity and work time lost in addition to substantial medical costs (Murphy, Connolly & Beynnon, 2003, p. 13). The most of the injuries are reported in the ankle and knee joint in the some sports such as football, hockey, lacrosse and basketball (Khabaz et al., 2014, p. 176). Entrancing force from different directions to the knee joint can cause some injuries in it such as injury or tear of Anterior Cruciate Ligament (ACL). Rupture in ACL is very prevalent and treatment of it has too cost and time (Khabaz et al., 2014, p. 176). It is obtained that statistical results had shown that 80 to 250 thousand of ACL injuries occur yearly that the most of them have 15 to 25 years old (Garrick & Requa, 2001, p. 2). Reconstruction of this ligament is

One of the most common sports related injuries are ACL tears. The leg that you once relied on is no longer stable. This injury requires major surgery, which is then followed up to a year off of sports, all the time hoping that once through it all you will be able to return to sports. The athlete not only has to recover physically from such a tough surgery but mentally from an injury as serious as an A.C.L. injury. Ligaments are tough, non-stretchable fibers that hold bones together. The anterior cruciate ligament that has been injured crisscrosses the knee to give it stability, and helps the leg to not hyperextend. The classic ACL injury occurs during a non-contact event usually when decelerating, stopping suddenly, twisting, cutting, or jumping.
