without letting the tibia slide too far posterior (Scuderi & Tria, 2010). These are the four most important ligaments in the knee that give the knee the most stability which are shown in Figure 3. Although the patellar ligament aides the stability of the knee, it is not as strong as the rest of the structure. Lastly, the iliotibial band (IT band) runs along the outside of the leg from the hip to the knee. The purpose of this is to limit lateral movement along the knee (Scuderi & Tria, 2010).
Stability is the most important function of the knee. To add to knee stability are the tendons. Tendons are elastic tissues that connect muscles to bones. They are what stabilize the knee and there are two major tendons that run through the knee.

A joint is covered in articular cartilage, the name articular coming from the fact that when the bones rub together they are articulating (Scuderi & Tria, 2010). Articular cartilage is fibrous connective tissue that is white, smooth and it covers the ends of the bone and as the joint moves it protects it, as mentioned by Scuderi and Tria (2010). Cartilage is what allows the bones to move more freely against each other. This articular cartilage covers the ends of the femur, top of the tibia and back of the patella, as pictured in Figure 4. It is kept slippery by the synovial fluid that is made by the synovial membrane (Marieb & Hoehn, 2013). The bones move easily since it is smooth and slippery. Finally the menisci are in the middle of the cartilage and those that the shock absorbers. According to the findings of Scuderi and Tria in 2010, in this cartilaginous structure there is the medial meniscus and lateral meniscus. The menisci are made up of fibrous crescent shaped cartilage. The medial meniscus is attached to the tibia on the inside of the knee and the lateral meniscus is attached to the tibia on the outside of the knee. The menisci sit on top of the tibia which allows the weight bearing force to be spread across a larger area and not have that pressure concentrated on one specific area (Scuderi and Tria, 2010). The menisci’s specific structure of a shallow shaped socket for the femur to sit in is another factor that helps stability. The menisci also help the articular cartilage from wearing away at the friction points because it is able to spread that weight bearing across the structure (Marieb & Hoehn,

    Also, wrapping your knees too tightly can bring out the possibility of constricting your movement. Make sure that the tightness of your knee wrap is suitable for the kind of exercise that you are doing. 2. Length of stretch The good thing about this product is that it is sturdy yet stretchy enough to give proper support. The longer you stretch your wrap, the tighter it will be on your knees.…

    The reticular coating has an erratically connective tissue, blood vessels, different glands, and lamellar corpuscles. On the other hand, the dermis layer is strong because of the collagen fibers all over the dermis. The blood vessels that are a part of the dermis is what preserves the homeostasis in the body temperature. C. Hypodermis- This subcutaneous tissue is near the dermis and holds adipose tissue. The hypodermis is not involved with the skin, but the tissue gives a way to store…

    In the early stage of prosthetic gait training, it is important to re-orientate TFAs to maintain the centre of pressure (COG) between two limbs, then only progress to the displacement of COG side to side and forward-backward. Walking aids can be prescribed to promote a symmetry posture and to improve weight bearing at the prosthetic leg. Lastly, an interdisciplinary approach is important in TFAs prosthetic rehabilitation in reducing or preventing musculoskeletal injuries.Next, hyperlordotic posture is commonly seen in TFAs and it may entail back pain among them. Aforementioned, hip extensor weakness is related to the above knee amputation and iliopsoas remains intact. This explains the presentation of limited hip extension range and hip flexors tightness at amputated side (Gottschalk, 1999).…

    Indeed, they can give you a shot in your knee to help give movement back and have less pain, it is called cortisone. Cortisone is a hormone produced by the adrenal cortex. It is also made synthetically for the use as an anti-inflammatory and antiallergy agent. Nonsteroidal anti-inflammatory medicines are used to reduce pain and swelling. Without treatment, the injured ACL is less able to control the movement of the knee, and the bones are more likely to rub against each other.…

    It is widely used in various biomedical applications and it is present in bone and primarily serve as structural protein of extracellular matrics. The tissues regeneration are often limited by their poor mechanical properties where it can be improved by included the hydroxyapatite compound. The combination of this properties between natural polymer and bioactive ceramic materials make the bone regeneration done smoothly (Maddela Swetha et al., 2010). Collagen is the major components of extracellular matrix such as tendons, ligaments and skin. The biocomposites of hydroxyapatite/collagen are inadequate so magnesium will be used as a doping to improve the mechanical and physical properties of bone in biomedical fields (Nebahat Degirmenbasi et al., 2006).…

    Synovial joint consists of a joint capsule, a joint cavity and a layer of cartilage over the ends of two joining bones. These joints are lined with synovial fluid. The articular cartilage over the joint ends absorbs jolts as it acts like elastic and it also provides a smooth surface for the joints to move frictionlessly. This fluid also helps in lubricating and protecting the bones. Cartilage is softer and much more flexible than a bone.…

    Anatomy and Function of the Knee The knee is the largest joint in the body; the joint is vital in supporting an individual when performing functional movements such as walking, running and jumping (Hamill, Knutzen and Derrick, 2014). Ref reports the knee joint moves in all three planes. Flexion and extension is seen in the sagittal plane, whereas internal and external rotation occurs in the transverse plane and adduction/abduction can be analysed from a frontal plane view. A ligamentous tissue capsule surrounds the joint, supporting the structure of the synovial membrane. The fluid produced from the synovial membrane lubricates the knee.…

Joints may also be classified structurally based on the components in the joint these may include: fibrous joints consisting of tough collagen fibers; cartilaginous joints made up of a band of cartilage binding bones (i.e. joint between the ribs and costal cartilage); and synovial joint (synovial membrane lining the capsule produces fluid lubricating the joint and decreasing friction) (BBC,…
