Posterior cruciate ligament Essays

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

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)

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

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

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

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

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

valgum where the lower legs rotate outwards (Credi, 2014). The third type of genu recurvatum is non-rotatory deformity recurvatum where the ankle and foot are normal just the knee is hyperextended. This type of genu recurvatum produces stress to the posterior soft tissue of the knee (Credi, 2014). There are people who train to become hyperextended because of the advantage it gives them in certain sports. All though the process is dangerous, the athletes that usually train to get genu recurvatum are children

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

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

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

patterns are being recognized. Anterior cruciate ligament (ACL) is a very commonly involved ligament in these injuries.8 The knee joint is a large compound type of synovial joint. Due to the lack of bony support, stability of the joint is highly dependent on its supporting ligamentous structures, and therefore injuries of ligaments and menisci are extremely common especially in active individuals like athletes, labours and soldiers. Anterior cruciate ligament is an intra-articular, extra synovial

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

Introduction The aim of this review paper is to access the anterior cruciate ligament (ACL) injury of the knee (tibiofemoral) joint, which is a common sport and exercise injury related to the musculoskeletal system. Investigation of the anatomy and physiology of the knee joint, and the diagnosis, etiology, pathophysiology, treatment, rehabilitation and prevention of ACL injuries will provide a descriptive epidemiology. This will aid readers in making informed management and treatment decisions

and never is with a torn ligament. He was escorted off the court and sent to the hospital where his career fell off a cliff and he has never been even close to as good as he was before his injury. Ligament tears in the knee are one of the worst sports injuries to obtain when as an athlete because they can never go back to how the ligament was to begin with. These injuries are common and happen to everyone, even the

collateral ligaments The collateral ligaments, found in the ankle, consist of three main bands on the lateral and nedial aspect. There are a number of bands that accompany the collateral ligaments. The lateral collateral ligaments are comprised of the anterior talofibular ligament (ATL), the calcaneofibular ligament (CFL) and the posterior talofibular ligament. The supplementary bands that are related with the lateral compound are the lateral talocalcaneal ligament (LTCL), and the posterior intermalleolar

joint to connect the humerus to the scapula and allow movement of the joint. (5) The four muscles are: the supraspinatus, the infraspinatus, the teres minor, and the subscapularis. (1) The supraspinatus is located above the scapular spine on the posterior of the scapula and attaches to the supraspinous fossa on the scapula (10). The infraspinatus is below the scapular spine and attaches to the infraspinous fossa on the scapula (11). The teres minor is found on the lateral border of the scapula (9)

Risk Factors for Stress Fracture You Should be Wary of Do you know what a stress fracture is? As its name suggests, a stress fracture is a type of fracture that occurs due to the overuse of your muscles and bones. It commonly occurs among athletes since they are actively using their body and do high impact trainings. In a stress fracture, when your muscles undergo a lot of wear and tear, it lessens their ability to absorb impact. Say, you’re a runner and the muscles on your feet undergo a lot
