-Medial collateral ligament (MCL) - Aids in stabilizing the knee towards valgus and varus forces of the knee joint. MCL originates above the joint line on the medial condyle of the femur and inserts below the joint line on the tibia. MCL also serves as a resist to external tibial rotation. MCL remains tight during knee extension and relaxed during flexion. - Injury may occur in MCL either as a result of a medially directed valgus force from the lateral side or it could occur from the external rotation
Across my many years of playing sports and being active, I have had multiple injuries and gotten banged up a few times. I have gotten cuts and bruises and twisted ankles many times, but only twice have I had a significant injury. When I was about nine years old, I accidentally flipped over the handlebars while riding a scooter and ended up unknowingly chipping a bone in my elbow. After about seven or eight years, an x-ray showed a bone chip floating around in the elbow joint, and surgery was needed
be along the line of the ligament of their knee. Within a few minutes of the sprain or tear, swelling will start to form around the knee area. This will cause suspicion that there is a knee injury and will help athletic trainers or doctors on the scene examining the athlete in discomfort. If the athlete tries to immediately move after the injury occurs they will be limping to help prevent the physical pain which is upon them. There are three grades of a medial collateral sprain. If the injury is
articulating surface. The C-shaped medial and lateral menisci serve to deepen the articulation at the superior surface of the tibia, thus enhancing the bony stability of the joint. Also adding to the joints stability are the two major pairs of ligaments: the cruciates and the collaterals. The medial and lateral collateral ligaments have a stabilizing effect in a lateral plane of motion, helping to prevent sideward displacement and over-rotation. The medial collateral attaches the femur to the tibia
Fundamentals of Anatomy and Physiology MED 111 Discussion 1 DISCUSSION TOPIC: Describe the body systems, listing major organs in each using anatomical planes and directional terms. In addition, discuss how the planes could be used to help a patient describe a patient concern. “An organ system is a group of anatomical structures that work together to perform a specific function or task.” (Christensen,). The organ systems of the body include: cardiovascular system, respiratory system, digestive system
football injuries are extremely dangerous and can lead to death, such as sprained ankles, dislocated shoulders, concussions, broken arms, and fractured knees. Goldbert et al. (75) relays that a sprain occurs when the ligaments around the ankle joint are stretched, twisted or torn. Ligaments connect bones and cartilage around a joint, keeping the bone stable.
longer, but many people push too much. Because of this new, harder and more intense way of playing, the rate of injuries has gone up. And by far, the most effected limb has been the knee. The anterior cruciate ligament (ACL) is the most commonly injured ligament of the knee. The ligament is most commonly injured during an athletic activity. Due to the fact that sports are an increasingly important part of day to day life in the United States, the number of ACL injuries has steadily increased over
also can also tear their anterior cruciate ligament, posterior cruciate ligament, and sometimes tear the medial collateral ligament or the lateral collateral ligament. As well with the ligaments be torn, blood supply and nerve blockage could happen making a dislocated knee very dangerous to the athlete who dislocates their knee. A dislocation is a medical emergency that usually ends up in surgery to fix not only the placement of the bones, but the ligaments as well. This injury can keep an athlete
UCTION: With the implementation of Title IX of the Education Amendment in 1972, and more recently a wide spread acceptance of females in the athletic world, the number of females competing in various sports has increased significantly at all competitive levels. Since 2004, the number of female athletes competing in Division 1 intercollegiate sports has increased by 13.6% (4). The number and value of grants and scholarships being given to these female athletes and their respective teams has also
supplied to each meniscus by the medial genicular artery. Each meniscus can be divided into three circumferential zones: the red-red zone is the outer or peripheral one third and has a good vascular supply; the red-white zone is the middle one third and has a minimal blood supply; and the white-white zone on the inner one third is avascular (Arnheim,1997). The medial meniscus is larger and more oval or C-shaped in the outline than the lateral meniscus. The medial cartilage is also more firmly fixed
In December of 2014, my brother partially tore his Anterior Cruciate Ligament playing indoor soccer. He went through several weeks of physical therapy to regain strength in his knee. One week after he was released by his doctor he attended a soccer clinic for his school's team. One hour into the clinic, he fell to the ground again. He was in a lot of pain and knew something had happened. The next day, he went back to his orthopedic doctor. That day he found out he had completely torn his ACL. Two
the body and it relies on a variety of ligaments, tendons, and soft tissue structures to maintain flexibility, stability, and strength. The knee joint is formed by articulations between the patella, femur and tibia. The knee joint is a hinge synovial joint. Like all synovial joints, the knee is surrounded by soft tissue structures and ligaments that support the joint and help facilitate a wide range of movement. The knee joint requires these multiple ligaments to keep the bones in place and maintain
This literature review is to examine just how females are more susceptible to knee injuries, especially having to do with the anterior cruciate ligament. Knee injuries are always prevalent in injuries. Through studies and research, it has been discovered that these types of knee injuries occur more frequently in females, especially an anterior cruciate ligament injury. In order to understand some of the biological reasons as to why the ACL is more commonly injured in females, one must take an in-depth
marked contrast with the upper limb. Forces are transmitted from the pelvis to the femur at the hip joint. As a ball and socket, the hip is intrinsically stable. The acetabulum being deepened by the acetabular labrum, as well as strong capsular ligaments provide for a strong hip joint. As the centre of gravity falls behind the hip joint, the tendency when standing is for the hip to be hyperextended. The strong iliofemora... ... middle of paper ... ...d, as well as the long flexor and extensor
B. Significance The anterior cruciate ligament (ACL) is one of four major ligaments of the knee joint: anterior (front) cruciate ligament, posterior (back) cruciate ligament (PCL), medial (inside) collateral ligament (MCL), and lateral (outside) collateral ligament (LCL). The ACL primarily works to coordinate function, promote overall stability of the knee, and prevent any unnecessary forward movement of the tibia. Many studies have attempted to determine why the ACL is associated with a high incidence
tibia is removed and the tibia is cut so that the tibial tray will fit properly. During total knee replacement surgery the posterior cruciate ligament can be affected, changing the flexion and extension. This change can affect the joint compression in the knee as well as the anterior-posterior translation. (steinbruck) In the study, posterior cruciate ligament balancing in total knee arthroplasty: a numerical study with a dynamic force controlled knee model, they created a dynamic deformable finite
Would I Let My Son Play Football? Do you worry about players in football? Are the violent sports in america too much for our youth? You would think twice on letting your son play football once you know the true consequences. Football is a high contact sport with a high risk injury rate. I wouldn't like my son to play football due to the consequences like brain damage, body injuries, and cause of death. According to Joseph Stromberg from Vox a website that falls in the category of News and Politics
with a Delta UFS (ATI). Heyse et al. (2015) analyzed the ability of Unicondylar Knee Arthroplasty (UKA) to restore the kinematics of the knee both in Balanced (normal installation of the implant) and Overstuffed (thicker inlay of polyethylene in the medial compartment) implant. The kinematics were measured in response to axial loading of 200 N in addition to a 15 Nm Abduction moment. Another example of utilizing an industrial robot matched with a UFS was presented by Kanamori et al. (2000). A Puma robot
Americans tear their Anterior Cruciate Ligaments (ACL) each year, myself included. Female athletes are eight times more susceptible to tear their ACL as a result of physiological and anatomic differences. Building up specific muscles around the knee can diminish the amount of strain on the knee. Therefore, female athletes should participate in strength programs to target reducing the risk of a life changing injury. The ACL is the most commonly injured of the four ligaments found
can occur in relation to sporting activities (Timpaka, et al., 2006). From the medical point of view, sports injuries is defined as a trauma or repetitive stress associated with the athletic activities. It can affect bones or soft tissues such as ligaments, muscles and tendons (Medical-Dictionary). Others may define it as an injury sustained during sporting activities for which an insurance claim is submitted (Bahr, 2008). Some may define sport injuries confined to injuries treated in a hospital casualty
