What Is Cartilage?
Cartilage is a form of connective tissue in the body. It is basically the precursor to bones during the development of an embryo. Some cartilage may remain and can be dispersed throughout the body, particularly to cover joints. The majority of the outer ear is also comprised of cartilage. In general, it is a distinctive tissue since there are no nerves or blood vessels in cartilage. Cartilage is also such a unique structure that makes it a flexible but very strong part in your body. 
Types of Knee Cartilage
Cartilage can be divided into different forms, which serve various purposes. In general, there are two kinds of cartilage in the knee joint. These include:
– Articular cartilage: This type is the main part of the joint’s smooth layer. It covers the ends of the bones, especially the kneecap’s back, shin bone’s top, and thigh bone’s end.
– Meniscus: This type forms the shock absorber between each bone. Unlike the articular cartilage, the meniscus is separated from the bone and located between the bone ends to help cushion joints.
