  • Cruciate Ligament Case

    Case Study #3 With the given information about the blow to the tibial tuberosity causing displacement of the tibia posteriorly relative to the femur, the structure most likely injured is the posterior cruciate ligament because it is located on the posterior side of the patella and posterior displacement of the tibia on fixed femur is restricted by the posterior cruciate ligament. The posterior cruciate ligament is the strongest ligament in the knee joint and helps with stability. Once the posterior cruciate ligament is torn or stretched, it loses its stability. There are many ligaments that make up the knee joint, also known as a hinge type joint which perform tasks such as flexion and extension. The tibiofemoral and patellofemoral are joints of the knee which aid in flexion and extension of the knee. 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). In order for the leg and foot to start turning a bluish color, the popliteal artery…

  • Exterior Cruciate Ligament Surgery

    In today’s society, injuries occur all around us: from a small paper cut, a tear of a ligament, or a bone breaking in the body. The anterior cruciate ligament (ACL) is one of the four central ligaments that stabilize the knee (Ref). This ligament prevents the tibia from sliding from the front of the femur and runs diagonally in the middle of the knee (ref). It is estimated that 70 percent of these tears occur through non-contact, while the other 30 percent occur from direct contact, whether it…

  • Muscle And Ligament Essay

    Muscle and Ligament tear Ligaments and muscles are tough fibrous bands of tissue that connect the bones to our joints. If they are twisted or put under excessive stress then they rupture and develop sprain and tears. The most common of muscle and ligament tear is the ankle sprain. Nearly 25,000 people suffer from some form of ankle sprain every day. Among sportspersons (especially those who play rugby, football or hockey), tearing in the Anterior Cruciate Ligament (ACL) is common. Muscle tear…

  • Collateral Ligament Essay

    Including the ACL there are four ligaments in your knee. The first is the medial collateral ligament(MCL). The MCL runs along the inside of the knee and it prevents the knee from bending in. The second is the lateral collateral ligament(LCL). This ligament runs along the outside of the knee and prevents the knee from bending out. The third is the posterior cruciate ligament(PCL). The PCL is in the middle of the knee and works with the ACL to prevent the tibia(shin bone) from sliding underneath…

  • Cruciate Ligament Research Paper

    The knee is made up of four main things: bones, cartilage, ligaments, and tendons. The knee is a ball in socket and the elbow is a relatively simple hinge joint which only allows flexion and extension. The radius is smaller of the two forearm bones and sits on the outside of the joint.As spoken about before the cruciate ligaments are made up of two types of ligaments, the anterior and the posterior. They are often referred to the ‘crucial’ ligaments because it is important that the help the knee…

  • Smooth Cruciate Ligament (PCL)

    The posterior cruciate ligament(PCL) is one of, if not, the strongest ligament in the knee and often described as the “primary stabilizer of the knee”(emedicine, Charles S Peterson, MD). While this is not one of the more common of the 4 stabilizing knee ligaments, it serves a great purpose. The posterior cruciate ligament is twice as strong and twice as thick than it’s “sister” anterior cruciate ligament (ACL). The PCL is extends from the lateral surface of the medial femoral condyle to the…

  • Anterior Tibiofibular Ligament Research Paper

    Anterior Tibiofibular Ligament The anterior tibiofibular ligament is often referred to as the high ankle ligament, and it is the one that is damaged when the foot is stuck on the ground and rotated inwardly. The ankle is a hinge joint that connects the foot and the leg, allowing up and down movement. The tibia and fibula bones of the leg form a slot where the talus bone of the foot fits between them. The talus is held to the tibia and fibula by ligaments. Anterior Tibiofibular Ligament The…

  • Anterior Cruciate Ligament

    There are many different parts to the knee, 2 bones, tibia and femur, 2 groups of muscles, quadriceps, which straightens the leg and the hamstrings which flex the knee. The knee cap, or the patella, which is the largest sesamoid bone in the body, synovial membranes, joints, cartilage, tendons, 4 ligaments, the anterior cruciate ligament (ACL), posterior cruciate ligament (PCL), medial cruciate ligament (MCL) and the lateral cruciate ligament (LCL). There are also sac like pouches called menisci…

  • Anterior Cruciate Ligament Analysis

    sporting activities (Meyer, 2005). The knee is made up of four distant ligaments that are prone to injury: anterior cruciate ligament (ACL), posterior cruciate ligament (PCL), lateral collateral ligament (LCL), and medial collateral ligament (MCL). The anterior cruciate ligament tear is one of the most common sport injuries. Among knee injuries, the Anterior Cruciate Ligament (ACL) is one of the most commonly disrupted ligaments in the knee (Boden, 2000). This injury happens from changing…
