Cruciate Ligament Research Paper
Tendons join the knee bones to the leg muscles that help move the knee joint. Ligaments are thick, strong bands of tissue that connect the knee bones and give stability to the knee.
• The anterior cruciate ligament helps to prevent the femur from moving backward on the tibia (or vice versa).
• The posterior cruciate ligament helps to prevent the femur from moving forward on the tibia (or vice versa).
• The medial and lateral collateral ligaments help to prevent the femur from moving side to side.
Two thick crescent shaped pieces of cartilage are the medial and lateral meniscus. They act as the shock absorbers between the femur (thigh bone) and tibia (shin bone). They are located at the outer and inner edge of the knee.

    The Anterior Cruciate Ligament (ACL) is one of the two cruciate ligaments of the knee, the other being the Posterior Cruciate Ligament (PCL). These ligaments are the stabilizers of the knee. The ACL is a strip of fiber tissue, which is located deep inside the knee joint. It runs from the posterior side of the femur (thigh bone) to the anterior side of the tibia (shin bone) deep inside of the knee. The ligament is a broad, thick cord the size of a person 's index finger. It has long collagen strands woven together in a fashion that permits forces of up to 500 pounds to be exerted. The function of the ACL is to prevent the tibia from moving in front of the knee and femur. The ACL also prevents hyperextension (or extreme stretching of the knee backward) and helps to prevent rotation of the tibia.…

    The knee can be subjected to multiple injuries such as the disruption of the anterior cruciate ligament (ACL), disruption of the medial collateral ligament (MCL), and a wide range of other injuries. This paper will describe the anatomy of the Posterior cruciate ligament and focus on injuries associated with it. It will also describe the causes of PCL injuries and what kind of examination and treatment of the PCL, as well as ways to avoid this kind of injury. It will also describe the degree of…

    The ACL also known as the anterior cruciate ligament is one of the four major ligaments in the knee that allows stability (about.com). ACL tears are most common in athletes and especially in female athletes. There are many ways to tear your ACL, whether it is with contact or no contact. There are also minimal symptoms for an ACL tear but they are very important to look for when an athlete is complaining about knee pain. The treatments for this injury also depend on the severity of the tear. The severity could determine if surgery is needed. These are all important things to know when you are in a situation with a person that has torn their ACL. Tearing your ACL can come at the snap of a finger, and that is what makes it scary for…

    ACL failure has been linked to heavy or stiff-legged landing; as well as twisting or turning the knee while landing, especially when the knee is in the valgus (knock-knee) position.Women in sports such as football (soccer), basketball, tennis and volleyball are significantly more prone to ACL injuries than men. The discrepancy has been attributed to differences between the sexes in anatomy, general muscular strength, reaction time of muscle contraction and coordination, and training techniques. A recent study suggests hormone-induced changes in muscle tension associated with menstrual cycles may also be an important factor ). Women have a relatively wider pelvis, requiring the femur to angle toward the knees .The majority of ACL injuries occur in athletes landing flat on their heels. The latter directs the forces directly up the tibia into the knee, while the straight-knee position places the lateral femoral condyle on the back-slanted portion of the tibia. The resultant forward slide of the tibia relative to the femur is restrained primarily by the now-vulnerable…

    Ligaments- Ligaments are tough fibrous bands of connective tissue that has a function to support the internal organs and hold bones together. A ligament is made up of dense fibrous bundles of collagenous fibers. They are spindle-shaped cells known as fibrocytes. Ligaments may be of two major types: yellow ligament is rich in elastic fibers, which are quite tough even though they allow elastic movement and white ligament is rich in collagenous fibers, which are robust and…

    The Anterior Cruciate Ligament (ACL) found in the knee connects the femur (thigh bone) to the tibia (shin) and provides stability to the knee. The ACL prevents the tibia from shifting too far forward and from rotating too far inward under the femur. The recent increase of this injury has parents, athletes, doctors, and coaches in fear. Athletes and parents fear the injury to due the expensive surgery, and the difficult physical emotional and mental recovery. The classic tearing of the Anterior Cruciate Ligament has no contact involved and occurs when an athlete is stopping suddenly, cutting, twisting, and jumping. The athlete…

    The anterior cruciate ligament (ACL) is one of the most common, severe, and devastating knee injuries in men and women in both contact and non-contact sports. Within the past 20-303 years the prevalence of ACL tears has been noted more significantly in the female athlete. Females were two times as likely to have ACL injuries as a result of player contact and three times more likely to obtain such an injury through noncontact mechanisms as their male counterparts1. The latest research2 indicates that female athletes are two to eight times more likely to experience anterior cruciate ligament rupture than male athletes. Mechanics of a woman’s body are leading to more ACL injuries. Numerous theories have been suggested to explain this problem. Many of these theories4,5 include both extrinsic and intrinsic factors. Intrinsic factors would be considered uncontrollable, and would include greater physiological rotatory laxity, smaller size of ACL associated with smaller intercondylar notch, valgus malalignment, hyperextension, diminished proproception, leg dominance, quadriceps dominance, hormonal influence, and postural alignment. Extrinsic factors would be considered potentially controllable. These include decreased strength and conditioning, inappropriate shoes, motivation, deceleration forces during injury, neuromuscular control, and body movement8. These extrinsic factors are the focus of prevention of ACL tears in the female athlete. Due to these factors, many questions have arisen regarding the increasing rate of ACL tears in the female athlete.…
