Cartilage is the main type of connective tissue in the body which is tough and flexible. Around 65–80% of cartilage is water and the rest is a gel-like substance called the ‘matrix’ that gives it its form and function. Cartilage is mostly found in the joints like shoulder, elbow, wrist, hip, knee, ankle as well as in the rib cage, ear, nose, throat and, between vertebral disks.
