The femur articulates with the hip bones of the pelvis.
When it comes to tetrapod animals, the femur, often known as the thigh bone, is the proximal bone of the hindlimb. The posterior section of the femur articulates with the tibia and patella to form the knee joint, while the top of the femur articulates with the acetabulum in the pelvis to produce the hip joint. Together, these three bones come together to form the knee joint. When compared to the other bones in the body, the femurs, both left and right, are considered to be the most robust. They are also the largest and most robust bones in humans.
