Articular Cartilage Injury

Three different types of cartilage are found in the body:

•   Articular or hyaline cartilage -- covers joint surfaces
•   Fibrocartilage -- such as in the knee meniscus and vertebral disk
•   Elastic cartilage -- such as the outer ear.

Articular cartilage is a complex, living tissue that lines the bony surface of joints. It provides a low friction surface, enabling the joint to withstand weight bearing movements, both for daily activities as well as athletics, including
Anatomy of the knee jointwalking and stair climbing, and work-related activities. In other words, articular cartilage is a very thin shock absorber.

Articular cartilage injuries can occur as a result of either traumatic mechanical destruction or progressive mechanical degeneration (wear and tear).
