 The PatellaThe patella, or kneecap, is the triangular-shaped bone at the front of the knee joint. The patella is held in place by muscles that surround it, and which are attached to the tibia by tendons. The patella protects the knee joint, which is like a hinge, and is the body's largest joint. It's unusual because it can swivel, allowing the lower leg and foot to turn from side to side. |
