SpletBoth the normal and horizontal components of the meniscus force could contribute to the friction. Liquids that are wet or have a small contact angle on surfaces will spontaneously condense into cracks, pores, and small gaps surrounding … SpletThe menisci ensure that these two bones with differently shaped surfaces work together smoothly. They enlarge the knee joint surface and absorb loads due to weight, ensuring they are evenly distributed across the joint. Meniscus injuries put the stabilising, impact absorbing and load distributing effect of the menisci at risk.

Sometimes these tears require surgical repair. However, whether they will respond well to surgery depends on the type of tear, its location, and whether or not there is blood flow in the affected area. fbt taySpletThe blood flow of the meniscus is from the periphery (outside) to the central meniscus. Blood flow decreases with age and the central meniscus is avascular by adulthood, which slows healing. Menisci show low-intensity on MRI images.

Meniscus tears usually take place when an athlete twists or turns their upper leg while their foot is planted and their knee is bent. Occasionally menisci can develop as a block or disk shape, which is called a discoid meniscus.
