Meniscus (anatomy) Generally, the term 'meniscus' is used to refer to the cartilage of the knee, either to the lateral or medial meniscus. Both are cartilaginous tissues that provide structural integrity to the knee when it undergoes tension and torsion.

How to Read a Meniscus in Chemistry Most liquids, including water, present a concave meniscus. A convex meniscus (sometimes called a backwards meniscus) is produced when the molecules of the liquid are more strongly attracted to each other than to the container. A good example of this shape of meniscus may be seen with mercury in a glass container. In some cases, the meniscus appears flat (e.g., water in some plastics).

meniscus The curved upper surface of a nonturbulent liquid in a container that is concave if the liquid wets the walls and convex if it does not. A disk of cartilage that acts as a cushion between the ends of bones in a joint.

Acute Phase One study found that arthroscopic pullout repair of a medial meniscus root tear provided better results than partial meniscectomy. Partial meniscectomy is the treatment of choice for tears in the avascular portion of the meniscus or complex tears that are not amenable to repair. Torn tissue is removed, and the remaining healthy meniscal tissue is contoured to a stable, balanced peripheral rim.

What is medial compartment osteoarthritis? The medial meniscus of the knee is a cartilage pad between the thigh bone (the femur) and the shin bone (the tibia). A healthy medial meniscus is smooth and allows the bones to glide without friction. The meniscus cartilage also absorbs shock from movement [source: NIAMS].

Cationic Contrast Agent Diffusion Differs Between Cartilage and Meniscus The contrast agent distributions within cartilage and meniscus were different. In addition, the normalized attenuation and diffusion flux were higher (p < 0.05) in cartilage. Based on these results, diffusion kinematics vary between cartilage and meniscus.

Lens (optics) Convex-concave (meniscus) lenses can be either positive or negative, depending on the relative curvatures of the two surfaces. A negative meniscus lens has a steeper concave surface and is thinner at the centre than at the periphery.

Torn Meniscus 1 The medial and lateral menisci are two large C-shaped cartilages that are positioned on the top of the tibia bone of the knee. 2  The knee is the largest joint in the body.  Cartilage within the knee joint helps protect the joint from the stresses placed on it from walking, running, climbing, and bending.

Tear of meniscus The meniscal tear is the most common knee injury. A meniscal tear tends to be more frequent in sports that have rough contact or pivoting sports such as soccer. The meniscal tear is more common in males than females.

Torn Meniscus A torn meniscus is damage from a tear in the cartilage that is positioned on top of the tibia to allows the femur to glide when the knee joint moves. Tears are usually described by where they are located anatomically in the C shape and by their appearance (for example, bucket handle tear, longitudinal, parrot beak, and transverse).

Arthroscopic Partial Meniscectomy versus Sham Surgery for a Degenerative Meniscal Tear We conducted a multicenter, randomized, double-blind, sham-controlled trial in 146 patients 35 to 65 years of age who had knee symptoms consistent with a degenerative medial meniscus tear and no knee osteoarthritis. Patients were randomly assigned to arthroscopic partial meniscectomy or sham surgery.

What Does a Torn Meniscus Mean? The meniscus is a cushion of cartilage that exists between the femur bone and the tibia bone that provides a shock absorbing function within the knee joint. There's typically two menisci one on the inside part of the knee as well as one on the outside part of the knee. One of the most common injuries to the meniscus is a meniscal tear where the shock absorbers or cushions of cartilage are torn. There are many different kinds of tears of meniscus depending on the mechanism of injury.

Treatment depends upon the severity, location, and underlying disease of the knee joint.

Definitions &Translations The glycocalyx is a type of identifier that the body uses to distinguish between its own healthy cells and transplanted tissues, diseased cells, or invading organisms. Included in the glycocalyx are cell-adhesion molecules that enable cells to adhere to each other and guide the movement of cells during embryonic development.

International Society of Genetic Genealogy Wiki Y-chromosome DNA haplogroups. Y-chromosome DNA (Y-DNA) haplogroups are determined by single-nucleotide polymorphism (SNP) tests. SNPs are locations on the DNA where one nucleotide has mutated or switched to a different nucleotide.Because a haplogroup consists of similar haplotypes, it is possible to predict a haplogroup from the haplotype. A SNP test is required to confirm the haplogroup prediction.NPs are locations on the DNA where one nucleotide has mutated or switched to a different nucleotide.

- Medical Definition of Meniscus injury. Meniscus injury: Injuries to the crescent-shaped cartilage pads between the two joints formed by the femur (the thigh bone) and the tibia (the shin bone). The meniscus acts as a smooth surface for the joint to move on. The two menisci are easily injured by the force of rotating the knee while bearing weight.

Medial Meniscus Tear A medial meniscus tear is defined as a tear in the fibrocartilage that makes up the two menisci in each knee. The lateral, or outer meniscus, and the medial, or inner meniscus work together to form a shock absorber for the knee.Traumatic events can overload the medial meniscus, causing partial or complete tears.edial Meniscus Tear. Symptoms: Common symptoms of a medial meniscus tear include a dull and constant pain in and around the knee when resting, that turns into a sharp pain when walking or bending the affected leg.

meniscus A lens that is concave on one side and convex on the other. The curved upper surface of a column of liquid in a container. The surface is concave if the molecules of the liquid are attracted to the container walls and convex if they are not. See also surface tension. A piece of cartilage shaped like a crescent and located at the junction of two bones in a joint. The meniscus acts to absorb shock.
