Knee

will mainly focus on the “knee joint”. This is because the knee is one of the most complex as well as the largest joint found in our body. Additionally, the knee is also one of the most vulnerable. This is because, while contributing to flexibility and movement, the knee carries more weight and pressure compared to other parts (Schmidler, 2016). For instance, when one walks, the knee supports approximately one point five times the body mass; when one climbs stairs, the knee supports three point our

The knee joint consists of three articulations: in the front is paltellofemoral articulation and other two articulations are between condyles of femur and tibia 1,3. When the knee is in full extension, rotation is impossible because the ligaments are tight. They will relax when the knee is flexed over 20 degrees and it will allow rotation 1,3. The main elements for knee stability are tendons and ligaments. Fibrous connective tissue forms a knee capsule, which is padded by a synovial membrane. Suprapatellar

Movement from the lower extremities of the human body depends on the strength, agility and flexibility of the knee. Bones, cartilage, muscles, ligaments and tendons assist with the knee getting the job done (NIH, n.d.). While supporting the body to walk, run and jump, the knee is at risk for enduring a torn anterior cruciate ligament (ACL). This type of injury can pose a threat to athletes and their careers. When the ACL is torn, the body will lose stability and the inability to bear the weight

The knee is one of the largest and most complex joints in the body. The knee has two joints the tibia (shin bone) joins the femur (thigh bone) this joint is known as the tibiofemoral joint the second joint is called patellofemoral which are joins between the kneecap and the femur. The patellofemoral and tibiofemoral works together to form the synovial hinge joint this hinge joint allows the knee to rotate a little and move side to side, it also allows the knee to be straight and bend. When standing

Lorenz, 2013). The knee joint consists of many different structures including the tibial-femoral articulation, the patella, and many cartilaginous structures. The meniscus is a fibrocartilaginous, crescent-shaped structure located in the knee between the medial and lateral tibiofemoral articulating surfaces (Mezhov, Teichtahl, Strasser, Wluka, & Cicuttini, 2014). There is both a medial and a lateral menisci, and their function includes loading variable transmissions across the knee joint, shock absorption

Background: Previous studies demonstrated that an abrupt change in conformity occurs during flexion of knee joint after total knee arthroplasty using the multi-radius femoral design implant. An abrupt change in conformity was shown to lead to paradoxical anterior sliding and anteroposterior movement. For this reason, a gradually reducing radius femoral design was introduced. Recent studies showed that the gradually reducing radius design helped to attenuate paradoxical anterior sliding and provide

complex pivotal hinge joint called knee. The upper and lower extremities are encompassed of cartilage, tendons and ligaments. There are two cartilage pads called menisci that diffuse the friction created at the tibial and femur joint. The main ligaments of the knee are Medial Collateral ligament (MCL), Lateral Collateral ligament (LCL), Anterior cruciate ligament (ACL), Anterolateral ligament (ALL), and Posterior Cruciate ligament (PCL). The knee is comprised of articular cartilage

When you hit the patella tendon a kick reflex is produced which is also known as the knee jerk (knee reflex). The main reason why hitting the patella tendon results in muscle contraction is so that the muscle is protected from unwanted harm such as being yanked vigorously or hyper extended. The muscle group that contracts in this reflex is the quadriceps muscles, so when a muscle spindle is stretched an impulse is instantly sent to the human’s spinal cord and a rapid response to contract the specific

The knee joint is the largest and most complex in the human body. Being able to understand the anatomy of the knee joint is a key factor in being able to identify the issues with the knee. People all ages often suffer from knee pain. Due to the amount of things that can go wrong, by understanding how the knee works, one can prevent new injuries and solve old injuries. The knee is made up of two joints, the tibiofemoral and the patellofemoral. The tibiofemoral joint is composed of the thigh and shin

processing, especially on knee image enhancement, as well as fuzzy theories are reviewed. The anatomy and imaging symptoms of knee injuries will also be briefly described. 2.2 Knee Joint The knee is a joint between two bones, the upper bone and lower bone. It is the part of the body, which is involved, in most of human movements, especially in sports. The ACL connects the upper bone and the lower bone, whereby the anatomy of the knee is shown in Figure 2.1. The component of the knee, along with the leg
