The femur, also known as the thigh bone, is one of the longest bones of the human body. The distal point of the femur refers to the area furthest away from its point of attachment, which in this case is the hip joint (please refer to the attached image). When referring to the image, you can see that the distal end of the femur articulates with the bone known as the tibia or shin bone. The tibia is the larger of the two bones located at the distal end of the femur. The tibia includes the knee and ankle joints. Therefore, the bone that articulates with the distal end of the femur is the tibia.
