Cruciate ligament

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 be from an outside object or player in sports (ref). This injury may occur when an individual is decelerating immediately while sidestepping, which may cause an uncomfortable landing on the knee joint (ref). Injured ACLs can be replaced by a substitute…

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…

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…

Posterior Cruciate Ligament Everybody has experience an injury in their life. If people where to sit down and think about all the injury’s they have had they could name a few. Some people would say their shoulder. Many people would say their hand or their foot. A lot of people can say that they injured their knee. It seems like knee injuries are more common now than ever. There are many athletes every year that suffer from a knee injury. Wither it be a professional athletes or a college athlete…

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…

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…

Anterior cruciate ligament (ACL) injuries are a increasing concern for athletes worldwide. Over 120,000 ACL injuries happen every year affecting more female athletes at the high school and collegiate levels. (Gornitzky Al, Lott A, YellinJl, Fabricant PD, Lawrence JT, Ganley TJ. 2015) With such a growing problem preventative measures are just as important as rehabilitation procedures. Neuromuscular training is gaining popularity as a preventative measure for these injuries. Research has shown…

recognized as Anterior Cruciate Ligament is considered to be one of your four focal ligaments within your knee that join to the femur, which is connected to the tibia. The knee is fundamentally a center of rotation that is seized together by the medial collateral, the lateral collateral, and both anterior cruciate and posterior cruciate ligaments. Anterior cruciate ligament (ACL) is known as a ligament in your knee that crosses from the base of the femur to the highest of the tibia. The main…

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…

The Posterior Cruciate Ligament (PCL) is located in the knee behind the Anterior Cruciate Ligament (ACL). It is the strongest ligament in the knee and is important in knee stability. The two cruciate ligaments which cross each other to form an “X”, control the back and forth motion of your knee. A ligament is a tough, relatively inelastic band of tissue that connects one bone to another. As one of five ligaments in the knee, the PCL connects the femur to the tibia and prevents the tibia from…
