Which bone sits over the front of the knee joint and is commonly called the kneecap?

• A. Patella
• B. Tibia
• C. Fibula
• D. Talus

Answer: (A)

The patella is the bone that sits at the front of the knee, commonly called the kneecap. It’s a small sesamoid bone embedded in the quadriceps tendon and acts like a pulley, increasing the quadriceps’ leverage as you straighten the knee. It also protects the front of the knee joint as it glides in the femur’s groove during movement. The other bones listed don’t occupy that front-of-knee position: the tibia is the shinbone that bears most of the body's weight and lies behind the patella, the fibula is the thinner bone on the outer side of the leg, and the talus is an ankle bone connecting the leg to the foot.
