What exactly are knee tears? Well to understand what these TEARS are, first you have to be able understand the structural composition of the knee, what it does and how it does these things. http://www.healthpages.org/anatomy-function/knee-joint-structure-function-problems/ The knee is one of the most complex and important hinge type synovial joints, and the largest joint in the body. It has two articulations, one with the femur and the tibia, and the second with or between the femur and patella, or knee cap. The knee is made up of four bones; the femur, tibia, fibula, and the patella. These four bones give the knee stability, strength, and flexibility. The femur is the single bone of the thigh, it the largest and longest and strongest …show more content…
Tendons are flexible but inelastic cord of strong fibrous collagen fibers connecting the bone to the muscle. In the knee joints they serve to stabilize the knee, there are two main and important tendons in the knee. The main tendons in the knee are the quadriceps and the patellar. The quadriceps tendon connects the quadriceps muscles of the thigh to the kneecap and provides the power for straightening the knee, and also helps hold the patella in the patellofemoral groove in the femur. On the other hand the patellar tendon connects the patella or knee cap to the tibia or shin bone. Which makes no sense, that it is called a tendon because tendons connect bones to muscle, and the patella connects the knee cap and the shin bone which are both bones not a muscle or bone. Because of this connection between two bones the patellar tendon can also be classified as a ligament. A ligament is a short band of tough, flexible, fibrous connective tissue that connects two bones or cartilages or holds together a joint. While the ligaments do serve to hold two bones together they also serve to give strength and stability to the knee which by itself has very, very poor stability. In total there are four ligaments in the knee joint however because the patellar tendon connects two bone it can be classified as a ligament, raising the amount of ligaments to the grand total of five ligaments in the knee. The medial collateral ligament or the MCL which connects the medial side of the femur to the medial side of the tibia, hence the medial part, and it also limits the sideways motion of the knee. The lateral collateral ligament or the LCL which connects the lateral side of the femur to the lateral side of the fibula, hence the lateral in the name, and it also limits the knees sideways motion. The anterior cruciate ligament or the ACL

    The hamstrings and quadriceps are both used to stabilize the knee during a landing, but in women, the hamstrings are often much weaker in comparison to the quadriceps. This causes the knees of women to wobble in and out during a landing, thus causing ACL injuries (Swift 5). The other theory as to…

    The tibiofemoral joint adds angle and assists with knee extension. The patellar ligament is inferior to the patella and located on the anterior surface of the tibial tuberosity. The tibial collateral ligament attaches to the medial meniscus and the fibular collateral ligament attaches to the lateral meniscus allowing them to both flex and extend. The posterior cruciate ligament and anterior cruciate ligament are limited by anterior and posterior translation. The lateral and medial meniscus are shock absorbers and stabilizers that absorb 40% of our body weight (Drake, Mitchell, & Vogl, 2012).…

    This is a weak position for the knee and it cannot support the force and therefore, buckles and the ACL is injured. The theory this study is testing is if the hip musculature can support the knee. If a person has good muscle strength in the hip and gluteus medius, that may help with the valgus force and reduce the amount of injury. There is evidence to show that when adding hip strengthening exercises to a prevention program, it helps reduce the risk of ACL injury.…

    A sprain occurs when the threads or fibers of the ligaments are stretched or torn. This injury can be classified as a grade I, grade II, or grade III sprain. Grade I sprains occur when the fibers are stretched but not fully torn, little tenderness and swelling, and the knee does not feel unstable or give out during an activity. Grade II Sprains occur when the fibers of the ligament are partially torn, little tenderness and moderate swelling, and the joint may give out during an activity. Grade III sprains occur when the fibers of the ligament are completely torn, and the ligament itself has torn completely into two…

    Joint pains and inflammation causes Knee is that largest joint in the body. The knee is located at the juncture of three bones, the femur, the tibia and the patella. The femur (the upper leg bone) and the tibia (the shinbone) are connected by the anterior and posterior cruciate ligaments. The joint is cushioned by the meniscus, a tough cartilage material, during movement. The patella (or kneecap) is a small bone, encased in tendons, that glides up and down in the groove on the top of the femur when the knee is flexed and extended.…

    More specifically, the PCL helps to maintain proper alignment of the femur and tibia and keeps them in place so that it doesn 't slip over the femur and cause the knee to buckle, lock, or collapse. It also helps to prevent the tibia from twisting outwards. The Knee is a very complex part of the body. With many ligaments, muscles and bones all in a single joint, it takes contributions from each component to create a functional knee. As mentioned before, there are five ligaments in the knee, posterior cruciate ligament, anterior cruciate ligament, medial collateral ligament, lateral collateral ligament and the patellar ligament.…

This finding concurs the data reported by Zeng et al (2011), and in contrast with the findings of LaPrade et al (2003) and Brinkman et al (2005). The PFL is also identified connecting the popliteal musculotendon junction to the head of fibula (Figure 1). In our case, the PFL was found as a ligament, similarly to one of the classifications presented by Zeng et al (2011).…

    In a skeletal system joints, ligaments, and tendons all go hand in hand. A joint is defined by two or more bones that meet. However, with the use of fibrous connective tissue, ligaments allow the joints to be held together. Ligaments are what prevent us from moving in an undesirable plane, another purpose they serve is that they limit the range or extent of normal movement (Wallace 2013). Unlike ligaments where the bone might be attached to another, tendons are fibrous tissue connecting the bones to the surrounding muscle.…

    Anatomy and Function of the Knee The knee is the largest joint in the body; the joint is vital in supporting an individual when performing functional movements such as walking, running and jumping (Hamill, Knutzen and Derrick, 2014). Ref reports the knee joint moves in all three planes. Flexion and extension is seen in the sagittal plane, whereas internal and external rotation occurs in the transverse plane and adduction/abduction can be analysed from a frontal plane view. A ligamentous tissue capsule surrounds the joint, supporting the structure of the synovial membrane.…
