What is the anatomy of the meniscus?
The menisci are C-shaped wedges of fibrocartilage located between the tibial plateau and femoral condyles. The menisci contain 70% type I collagen. The larger semilunar medial meniscus is attached more firmly than the loosely fixed, more circular lateral meniscus.
What are the 3 parts of the meniscus?
You can break up the meniscus into three zones, the anterior horn, the body, and the posterior horn. One of the problems the meniscus runs into is that because it is a cartilage, it lacks a certain amount of blood flow to the tissue for proper healing properties.
What are the 4 functions of the meniscus?
The menisci increase stability for femorotibial articulation, distribute axial load, absorb shock, and provide lubrication and nutrition to the knee joint.
What is a meniscus and its function?
The meniscus is often thought of as being shock absorbers between the thighbone and the shinbone. They work to help in the reduction of wear and tear on the knee’s cartilage and bones and assist in guiding movement.
What type of tissue is meniscus?
Meniscus tissue is composed of outer, dense connective tissue and inner fibrocartilage regions (Fig. 1.4(b)) (Verdonk et al. 2005). The outer region is vascularized dense fibrous connective tissue that connects to the internal knee joint capsule.
What is a meniscus made of?
The menisci are made of fibrocartilage, a special type of cartilage. They function as shock absorbers and force distributors that help to stabilize the knee. Injuries to the meniscus are the most common, and the medial meniscus is torn more often than the lateral meniscus.
What type of tissue is a meniscus?
What shape is the meniscus?
A meniscus is a crescent-shaped fibrocartilaginous anatomical structure that, in contrast to an articular disc, only partly divides a joint cavity. In humans they are present in the knee, wrist, acromioclavicular, sternoclavicular, and temporomandibular joints; in other animals they may be present in other joints.
What two bones is the meniscus between?
A meniscus is a piece of cartilage found where two bones meet (joint space). Menisci (plural of meniscus) protect and cushion the joint surface and bone ends. In the knee, the crescent-shaped menisci are positioned between the ends of the upper (femur) and lower (tibia) leg bones.
Where is meniscus found?
The meniscus is a c-shaped pad of cartilage in the knee that acts as a shock absorber. Each knee has two menisci. Meniscus tears are common knee injuries.
What is the meniscus made of?
Why meniscus is formed?
Water molecules are attracted to the molecules in the wall of the glass beaker. And since water molecules like to stick together, when the molecules touching the glass cling to it, other water molecules cling to the molecules touching the glass, forming the meniscus.
What are the types of meniscus?
The menisci — the medial meniscus and lateral meniscus – are crescent-shaped bands of thick, rubbery cartilage attached to the shinbone (tibia). They act as shock absorbers and stabilize the knee. The medial meniscus is on the inner side of the knee joint. The lateral meniscus is on the outside of the knee.
What is meniscus and its types?
The meniscus (plural: menisci, from the Greek for “crescent”) is the curve in the upper surface of a liquid close to the surface of the container or another object, caused by surface tension. It can be either concave or convex, depending on the liquid and the surface.
How meniscus is formed?
What is meniscus and types?
A meniscus is a moon-shaped section of cartilage that cushions the knee between the top of the shinbone (lower leg bone, or tibia) and the bottom of the thighbone (upper leg bone, or femur). Each knee has two menisci: The lateral meniscus is in your outer knee, and the medial meniscus is in the inner knee.
What is the difference between a meniscus and cartilage?
is that cartilage is (anatomy) a type of dense, non-vascular connective tissue, usually found at the end of joints, the rib cage, the ear, the nose, in the throat and between intervertebral disks while meniscus is a crescent moon, or an object shaped like it.
How serious is a torn meniscus?
Left untreated, a meniscus tear can limit your daily life and ability to participate in exercise and sports. In serious cases, it can develop into long-term knee problems, like arthritis. Keeping this in view, what happens if you leave a torn meniscus untreated? An untreated meniscus tear can deteriorate and may come loose within the knee joint.
How do you know if you tore your meniscus?
A popping sensation
What is the recovery time for a meniscus surgery?
Give you a prescription for medications to manage pain after the surgery.
