Knee Joint Research Paper

The bones that comprise the knee joint fit together because the lateral condyle of the femur and tibia are both articulated by the lateral meniscus. Both medial condyle of the tibia and femur are articulated by the medial meniscus. The patellar is found within the quadriceps tendon ligament of the knee. What structures are associated with the medial surface of the knee?

The Anterior Cruciate Ligament (ACL) and the Posterior Cruciate Ligament (PCL) are located inside the knee joint. The ACL and PCL form an ‘X’ behind the kneecap (patella), with the ACL resting in front of the PCL. Both of these ligaments are responsible for controlling the back and forth motion of the knee joint; however, the ACL is responsible for stabilizing the kneecap ). In addition, the ACL is responsible for preventing the shin bone (tibia) from sliding forward on the thigh bone (femur). The ACL provides the knee with stability while an individual pivots or twists. This ligament is critical because without it, performing any kind of rotational activity is impossible, particularly when it comes to playing sports like soccer and basketball.

The ACL originates from the medial and anterior aspect of the tibial plateau and runs superiorly, laterally, and posteriorly toward its insertion on the lateral femoral condyle. Together with the posterior cruciate ligament (PCL), the ACL guides the instantaneous center of rotation of the knee, therefore controlling joint kinematics. To a lesser degree, the ACL checks extension and hyperextension. The ACL is not as strong as the posterior cruciate ligament (PCL), and it is less strong at its femoral origin than at its tibial insertion. Muscles surrounding the knee joint contribute to knee stabilization during lower extremity movements.

If you expereince a sore or achy knee on a regualr basis, it's important to note that a supportive deevice may prove to be espeially beneficial. There's a wide assortment of braces, tapes and straps avaavle that can help to provide some well needed supported to the involved muslces and joints. In this overview we'll take a look at the benefits that tapes, braces and straps have to offer.

The popliteus muscle is a minor flexor of the knee. It penetrates the joint capsule to find its origin on the lateral condyle of the femur, and passes obliquely to insert on the medio-proximal tibia. Its main function is to help stabilize the knee, but is also able to rotate the femur on the tibia to unlock the knee.

In this study, a randomized and concealed method supported by a computer was conducted prospectively for patients who showed signs of radiographic knee OA. In addition, without knowing further about the clinical status of participants, knee radiographs were assessed in the study of baseline and follow ups by an experienced surgeon. The baseline characteristics of subjects such as age and BMI were not significantly different. Criteria included were the radiographically confirmed as knee OA (a score ≥ 1 out of 4 on the K/L scale), ability to walk to the site, understand and make signature on the written consent of information form and report the data required. However, the research did not include the participants

Steven Claes is known to have discovered a new ligament in our knee that could supply us with explanations to many unanswered questions. First, what is a ligament? Ligaments are bundles of connective tissue that connect one bone to an adjacent bone, or from one bone to a bone next to it. These ligaments are crucial in preventing unwanted and damaging movements such as . They are also important in maintaining stability of the joint while it is in motion. The ALL or anterolateral ligament, is a newly found ligament located in the knee joint. It is located towards the front of the knee and is known to be an important restraint of internal tibia rotation. This ligament is situated at the prominence of the lateral femoral epicondyle slightly anterior to the origin of the lateral collateral ligament, also known as the LCL. It has firm attachments to the lateral meniscus enveloping the inferior lateral geniculate artery and veins. This ligament connects the .. scientific name or in other terms, the thigh bone to the shin bone. Due to the location of this ligament, researches believe it keeps the knee from an unwanted inward motion. The anterolateral ligament is said to have an effect on the rotational

The quads include the rectus femoris, and the vastus lateralis, intermedius, and medialis. This muscle group shares a common tendon at insertion. The patellar tendon inserts at the tibial tuberosity, and within this tendon lies the patella. The patella is anterior to the femur-tibia articulation, and this sesmoid bone increases the leverage of the quads by acting as a pulley. The major contributor to the stability of the knee joint is the strength of the quads. The only muscle that assists in extension is the tensor fascia lata.

Third down and one, the quarterback takes the snap and rolls out to the left. Nobody is open. He steps up in the pocket and decides to run, planting his leg into the dirt, he tries to make a quick juke, but gets hit and blows his ACL. Because knee injuries plague millions of people each year, victims should learn about its preventions, types and treatments before it happens to them.

The third type of ligament found in the knee is the medial collateral ligament also known as tibial collateral ligament this ligament limits sideway motion of the knee it attaches the medial side of the femur (thigh) to the medial side of the tibia (shin bone). The lateral collateral ligament attaches the side of the femur (thigh) to the lateral side of the fibula (long thine bone) and it limits sideways motion of the knee it is also called fibular collateral ligament (Schmidler). The last ligament found in the knee is the patellar ligament this ligament attaches the kneecap to the tibia (shin bone). Schmidler stated, “The pair of collateral ligaments keep the knee from moving too far side-to-side. The cruciate ligaments crisscross each other in the center of the knee. They allow the tibia to “swing” back and forth under the femur without the tibia sliding too far forward or backward under the femur.” The four ligament mentioned by Schmidler are the most vital structures in keeping the knees stability the patellar ligament also helps with stability. Another major part that makes up the knee is tendons. Tendons provide an attachment of muscle to bones they are elastic tissues and also tendons aid to alleviate the

There are two types of ligaments, Collateral and Cruciate. The Collateral ligaments control the sideways movement of the knee and protect it from unusual movement. These ligaments are found on the sides of the knee. The MCL is located on the inside of the knee while the LCL is located on the outside of the knee. The Cruciate ligaments control the back and forth motion of the knee by crossing each other on the inside of the knee and forming an “X”. The ACL is located in the front part of the “X” while the PCL is located in the back (OrthoInfo, 1995-2015).

The ACL extends posteriorly and laterally from a point anterior to the intercondylar area of the tibia to the posterior part of the medial surface of the lateral condyle of the femur (Tortora, 2009). In layman's terms, it extends diagonally in the middle of the knee joint connecting the shin and thighbones. The ACL is a complex structure that has an irregular nature. It has a multi vesicular structure that had been ignored for many years as it was originally thought to function as a simple band of fibers with constant tension as the knee moves. Multiple collagen bundles lead to the multivesicular nature of the ACL (Arnoczky, 1983). There are three functional bundles that make up the ACL; the anteromedial, intermediate, and posterolateral.

ranged from 7.5% to 11.1% in East Asia, 6% to 13.7% in South Asia, and 9% to

The knee joint consists of four ligaments, two intra-capsular which are the ACL and the PCL and two extra-capsular ligaments including the MCL and LCL. The ACL is an extremely strong stabiliser which prevents anterior displacement of the knee. The ACL is a ligament and therefore connects one bone to another, the femur with the tibia. The ACLs origin is from the anterior intercondylar eminence of the tibia (home,2017) and the fibres pass upwards, backward and laterally inserting into the lateral condyle of the femur.

The knee is a hinge joint which gives the legs mobility. The muscles and ligaments of this joint allows flexion and extension of the leg. “Because the knee supports the majority of the body weight, it is at risk of overuse and traumatic injuries” (France). The knee is composed of 3 major bones; the femur, tibia, and the fibula. The femur is the biggest bone in the human body, the inferior end flares out into two rounded landmarks called femoral condyles. Their name comes from the side of the body they are on, which is where we get Lateral Femoral Condyle and Media Femoral Condyle. Superiorly to these condlyes are the medial and lateral femoral epicondyles. The bones inferior to the femur are the Tibia and Fibula. The superior end of the Tibia flares out into slightly concave structures called the Tibial Plateaus. A crescent wedge shape of cartilage sits in each plateau. These are the Medial Meniscus and the Lateral Meniscus. This cartilage acts as a shock absorber and distributes forces. “The menisci are bathed by the synovial fluid of the knee” (France). The meniscus is what separates the each side of the Tibia and Femur and the transverse ligament connects each menisci. There is a circular bone on the
