Collateral Ligaments Of The Knee

The anterior cruciate ligament (ACL) is one of the four main ligaments in the knee joint that connect it to the shin bone (tibia) and thigh bone (femur). It 's located deep within the joint, behind the kneecap (patella), above the shinbone, and below the thighbone. The ACL lies diagonally across the middle of the knee and plays a role in keeping the knee stable during movement. Partial tears of the ACL can occur, but are rare. Most ACL tears are either near-completes or complete tears. After experiencing an ACL tear, an athlete has a 15 times

First and foremost, your knee has four ligaments. The ligaments line up your bones and help control the way you move. It prevents the shins from moving too far forward. ACL injuries sometimes requires surgery.

The ACL is one of the most frequently uinjured ligaments of the knee.( 59 )

The medial collateral ligament (MCL) is a tough band of tissue that connects the thighbone to the shinbone. Your MCL is located on the outside of your knee. It prevents your knee from moving too far inward and helps keep your knee stable. A MCL sprain is an injury caused by stretching the MCL too far. The injury can involve a tear in the MCL.

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.

This short and round ligament, like all other ligaments, prevents slippage within the joint and allows the joint to properly pivot when performing an action (Duff 300). Without this particular ligament, the knees would be fragile and more susceptible to injury. Therefore, it would be impossible to do the simplest movements that are done by humans everyday, like walking and even sitting. This is one reason why many athletes should be aware of the physical indications that arise if they have torn their ACL while participating in athletic activities.

The Anterior Cruciate Ligament also known as the ACL is deemed the most commonly torn ligament in the knee and can result from both contact and noncontact injuries. Most Anterior Cruciate Ligament injuries result from an extreme force on the lateral side of the person’s knee causing a valgus force which pushes the knee inward (Kisner & Colby, 2012, pp. 802-803). This injury to the side of the knee can also cause a “Terrible Triad” injury which also injures both the medial meniscus and the medial collateral ligament (Kisner & Colby, 2012, p. 803). Our textbook further states that “the most common noncontact mechanism is a rotational mechanism in which the tibia is externally rotated on the planted foot….this mechanism can account for as many as 78% of all ACL injuries” (Kisner & Colby, 2012, p. 803). If the person does not seek medical help with this injury they are susceptible to also injuring the remaining support ligaments as well. Patients usually present with joint effusion; possibly 25 degrees of flexion, joint swelling if blood vessels are involved, limited ROM, stress pain and instability along with quads avoidance gait patterns (Kisner & Colby, 2011, p. 208)

What is it? When you injure your ACL you're usually put a tear in your Anterior Cruciate Ligament (www.mayoclinic.org). Thus for when you are injured you will be caused you to fall down. Your ACL is located in the middle of your knee. It is one of the four main ligaments in your leg alongside with the MCL, PCL, and LCL (www.mayoclinic.org). Since your

Total Knee Replacements are the most successful procedures in all of medicine, accounting for 600,000 knee replacements each year in the US. The knee is the largest joint in the body, which is why it’s very important to have healthy knees in order to get around to perform daily activities. The knee consist of the lower femur, the upper end of the tibia, and the patella. The ends of the three bones touch, which is covered with articular cartilage, this is a smooth substances that protects the bones and enables them to move smoothly. Also, located between the femur and tibia are the menisci. The menisci are C-shaped wedges that act as “shock absorbers” this provides cushion for the joint as well. Then, the large ligaments also play a role as well, they hold the femur and tibia together to provide stability. The long

When it comes to your ability to move around, participate in sports, and simply walk, your knee joints are vital. The knee itself is made up of multiple ligaments, bones, and tendons and of all of these different parts that need to work together to make the joint work. One of these parts is called the medial collateral ligament or MCL. It is responsible for adding a little more stability to your knee and leg as well as preventing your knee from bending in dangerous directions. If you are noticing some pain in the inside portion of your knee or possibly you feel unsteady on one or both of your feet you may have injured your MCL.

A torn ACL is one of the most serious and common knee injuries. Many aspects play a role in the treatment and rehabilitation of this injury. This paper will discuss the anatomy of the knee, describe a torn ACL, and the rehabilitation.

The knee joint is formed by the articulation of the distal end of the femur and the proximal end of the tibia. The fibula is only involved to the extent that it serves as an attachment site for connective tissue. In this paper, the anatomy of the joint will be discussed.

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 anterior cruciate ligament (ACL) is crucial to knee stability as its function is directly related to the anatomical morphology.9 The ACL is one of the two ligaments that interconect the femure and tibia in the intercondylar sector of the knee.4 It consists of two bundles: antromedial (AMB) and postrolatral (PLB). Both bundles originate from the postero-medial aspect of the lateral femoral condyle and run in an oblique manner to insert on the anterior region to the intercondylar tibial eminence.17 The ACL is comprised of multiple collagen fascicles, mainly type I collagen, surrounded by connective tissue and covered by the synovial membrane.17 The average width of the ACL is 11mm and the mean length of the AMB is 33mm, while it is 18mm for the PLB.14

The Anterior Cruciate Ligament (ACL) is located inferior (underneath) to the Femur and superior (above) to the Tibia. The ACL allows range of motion the Tibia.
