What Is A Hinge Joint In The Knee

The knee is an integral joint in terms of movement, but this joint absorbs much impact while it supports the weight of the body. Depending on the type of activities that you engage in, the level of impact absorbed by your knee may vary. The knee joint connects the kneecap (the patella) with the second bone in the lower part of the leg (the fibula). It also connects the shin bone (the tibia) with the thigh bone (the femur). Four ligaments serve to stabilize the joint; these ligaments are known as the Lateral Collateral Ligament, Medial Collateral Ligament, Posterior Cruciate Ligament, and the Anterior Cruciate Ligament.

The ACL is the Anterior Cruciate Ligament is in the front of the knee and serves a few purposes such as being in control of the knee twisting and keeps the tibia from going over the femur, and keeps the knee from hyperextending.

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) 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

These boots move the forces caused by a fall to the knee rather than the ankle or lower leg. The ACL injury usually occurs when the knee is forcefully twisted, or hyper-extended. Many patients recall hearing a loud pop when the ligament tears, and feel the knee give way. This injury has received a great deal of attention from orthopedic surgeons over the past 15 years and very successful operations to reconstruct the torn anterior cruciate ligament have been performed.

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 ACL works with the PCL (posterior cruciate ligament), which crosses over it to form an "X." Together, these two ligaments help keep the knee stable when rotating. The ACL keeps the shin bone in place and prevents it from moving too far forward and away from the knee and thigh bone. It prevents the shin bone

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 “…is a primary restraint to anterior drawer of the tibia” (Halewood & Amis, 2015, p. 2790) which means that it keeps the tibia from moving too far forward. Providing controlled extension, it is also a primary player in knee stability (Kisner & Colby, 2012, p. 803). It

An ACL is the Anterior Cruciate Ligament (ACL) which is a ligament in the knee and is an essential internal stabilizer of the knee joint and helps in restraining hyperextension. It is injured when it’s when the biomechanics of this ligaments limits are exceeded or over stretched, often with a hyperextended mechanic. It was thought that

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

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.

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.
