The menisci of the knees are semicircular fibrocartilaginous structures consisting of a hydrophilic extracellular matrix containing a network of collagen fibers, glycoproteins, and proteoglycans maintained by a cellular component. The menisci are responsible for more than 50% of load transmission across the knee and increase joint congruity thereby also aiding in fluid film lubrication of the joint.
Meniscus is derived from the Greek word meniskos meaning crescent moon.1 A meniscus is a crescent shaped fibro cartilaginous structure which part divides a joint,2 usually while adding concavity. Menisci (pleural) are present in many joints throughout the body, most notably the knee.
You have a lot of control over the factors if you do not rely on others for food. Eating foods high in fats and cholesterol is the consumers fault.

Cardiovascular disease is a unfortunate disease that is commonly from improper eating habits and exercise. The amount of responsibility is completely the consumers or the guardians of the consumers. :) Im pretty sure this is what you were asking and im sorry if it wasnt.
Cross training lets you include low-impact activities, like bike riding and swimming, that provide the benefits you need without putting more stress on your joints. Cross training can also help you recover from a back or knee injury.
