The kneecap (patella) is a small triangular bone. It is just one of the many parts that make up the knee joint. Some of the other parts are muscles, ligaments, and leg bones. The kneecap provides leverage for your muscles as they bend and straighten the leg. It also protects the knee joint.

From the front, you can see the kneecap’s slightly rounded, shield-like shape. |
From the back, you can see cartilage. This is tough tissue that covers the bone. It helps the kneecap slide easily against the thighbone. |
From the top, you can see that the kneecap sits in a groove or “track” in the thighbone.
