The femur, or thigh bone, is the longest and strongest bone in the body, providing support and mobility for the leg through its long shaft and large proximal and distal ends that connect to the hip and knee joints. In contrast, the patella, or kneecap, is a small, flat, triangular bone that acts as a protective shield for the knee joint and enhances the leverage of the quadriceps muscle during leg extension. Structurally, the femur is a long bone with a robust diaphysis, while the patella is classified as a sesamoid bone embedded within the quadriceps tendon, reflecting their different functional roles in locomotion and joint protection.
