Anterior Cruciate Ligament Problem: Do gastrocnemius/soleus and hamstring tendon strains change the biomechanics of running in athletes and increase the risk of ACL tears? Rationale: To determine if multiple witnessed ACL tears post calf strains were a coincidence or if these injuries increase the risk of ligament tears due to a change in biomechanics. Hypothesis: Gastrocnemius/soleus and hamstring strains increase the risk of ACL tears. Review of Background The anterior cruciate ligament (ACL)

Male and Female Anterior Cruciate Ligament Correlation The Anterior Cruciate Ligament (ACL) is a commonly injured ligament located in the knee. Lately, there has been a lot of research pertaining to which gender is more susceptible to injuring this ligament, as well as which gender is ACL injuries most prominent. Through various studies and abundant amounts of research, women have been found to be more prone to ACL injuries for three main reasons. These include anatomy of the female body, biomechanics

The purpose of this literature review was to evaluate the research on alternative rehabilitation methods for anterior cruciate ligament (ACL) reconstruction. The anterior cruciate ligament is one of the four ligaments that stabilize the knee. Poster to the patella, the ACL prevents the knee joint from moving during quick changes in movement. Pivoting and cutting are the most common movements that cause the ACL to rupture.1 ACL tears were found to be the knee’s most commonly diagnosed sports injury

torn ACL. ACL stands for Anterior Cruciate Ligament (McDaniel). “The ACL is one of the four major ligaments that works to stabilize and support the knee. The ACL is “behind the patella and connects the Femur to the tibia,” (McDaniel). It prevents the tibia from moving too far forward on the femur and it limits the rotational movement of the knee,”(“Why do Females”). Basically the ACL is a stabilizer of the knee (McDaniel). An ACL injury happens when the ligament has been overstretched or when when

another. Most of the time, normal body movements do not incur injuries. As a result, knee injuries are common in sports such as soccer, football, and basketball, most of which involve frequent sudden stop movements among athletes. The Anterior Cruciate Ligament (ACL) has been studied in many different ways

Keep Your Knees Healthy and Strong with the Help of the Following Ten Tips The largest joints in the human body are the knees. The knees provide the legs with stability, flexibility and support that it needs for turning around easily, walking, crouching, standing, jumping and running. This is why it is extremely important to keep your largest joints healthy and strong. With age, knees become weaker, so knee issues are usually a problem of older people. However, people of any age can experience

preservation of the both cruciate ligaments.19 In 1973, Marmor designed a modular knee for unicompartment & bicompartment replacement .20 The Total Condylar Prosthesis (TCP) designed by Insall and others, its introduction in 1973 marked the beginning of the modern era of total knee arthroplasty. (Fig. 20) This prosthesis design allowed mechanical considerations to outweigh the desire to reproduce anatomically the kinematics of normal knee motion. Influenced largely by the previous ICLH

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. With this, the medical cruciate ligament functions to stabilize the

Both meniscus and ligaments were designed in CATIA as different components. The data’s for length and cross sectional area of ligaments, ligament insertion sites, menisci peripheral length range, area of Contact points of meniscus were obtained from previous FE and experimental studies. At last stage of the design; bones, meniscus and ligaments were assembled in CATIA. B. Finite Element Mesh The assembled solid Model from CATIA

One of the most common knee injuries is an anterior cruciate ligament sprain or tear. Most athletes who participate in high active athletic activities and high demand sports, like rugby, baseball, and golf, are more likely to injure their anterior cruciate ligament. An anterior cruciate ligament injury is the over-stretching or tearing of the anterior cruciate ligament ACL in the knee. A tear could be small, or it could be very large in the amount of tearing in the ACL. Three bones meet to form your

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

What is the medial collateral ligament (MCL)? The MCL is one of the main four ligaments that is part of the knee. This ligament is a broad, thick band that runs down the inner part of the knee, from the femur to the top of the tibia, but is located outside the joint itself. The job of the MCL is to support the knee with the help of the other ligaments in the knee. When stress is applied to this ligament it aids control in transferring the join through a normal range of motion. Also, the MCL prevents

injuries occur frequently throughout college football and other professional sports and although they may all seem different; they also have numerous similarities. In today’s society it is extremely common to see an athlete tear their anterior cruciate ligament (ACL) or receive a concussion. While both injuries are viewed as completely different, surprisingly they can be tied together through multiple factors. Although the harm is done to opposite parts of the body, coaches must remain equally aware

Bracing, Crutches and Rehabilitation Once an anterior cruciate ligament has been injured, treatment has to be carried out as soon as possible. Due to the location of the ACL (at the level of the knee) it poses significant problems for activities of daily life such as walking, climbing and sitting. Depending on the severity of the injury, an ACL reconstruction surgery may be performed. During this reconstructive operation, the deficient ligament is repaired using a tendon graft. In most cases the hamstring

involed abrupt starting and stopping during basketball or softball. With the help of my team, we will investiage the functions of the ACL, treatment options and why I may have suffered these injuries as a young female athlete. The anterior cruciate ligament, or ACL, prevents forward movement of the tibia, off of the femur. The ACL also prevents hyperextension of the knee, hence it allows for the knee joint to be stable and allows for dynamic motion. For those who suffer an ACL injury and do not

quarter of Sunday’s New York Knicks win over the Miami Heat, veteran point guard Baron Davis suffered a horrific knee injury which was a partial tear of the patella tendon is his right knee and complete tears of the right anterior cruciate and medial collateral ligaments, according to the New York Knicks. All of this Baron Davis suffered with the injury in the third quarter of Game 4 in 2012 in the series against the Miami Heat on Sunday afternoon. The 33-year-old was dribbling down the court and

Genu Recurvatum, otherwise known as back knee, is hyperextension of the knee. Hyperextension of the knee occurs when the knee joint passes more than 180 degrees. When this happens, the knee can usually pass about 10 to 15 degrees more than the standard degree (Anonymous, 2015). Here, the femur bone leans on the anterior part of the tibia instead of being balanced out (Loudon, Goist, Loudon, 1998). This could cause damage to the soft tissue around it, and increased stress on the knees. Genu Recurvatum

Without a doubt, there has always been a great risk of injury while participating in contact sports. The participants involved in any contact sporting event are always susceptible to being injured. These participants are completely aware of the everyday risk, but the energy that these sports bring, keep them going regardless. Over the years, there have been countless numbers of injuries due to the nature of these sports, but still millions of people young to old gain interest everyday. While people

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

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. It is just a matter of protecting oneself. Zaleuke 2 1. What is an ACL? ACL stands for anterior cruciate ligament. This ligament
