Tibia and fibula

The tibia is the stronger of the two bones of the leg, it is the second largest in the human body, the largest being the femur. It is medial to the fibula. The tibia articulates with the femur and patella superiorly, the fibula laterally and with the talus inferiorly.

The fibula located laterally to the tibia and it is the smaller of the two bones and is one of the most slender long bones. Its upper extremity is small, placed toward the back of the head of the tibia, under the knee joint but not included in the formation of this joint. Its lower part changes to be a little forward and becomes more anterior to that of the upper extremity; it projects below the tibia, and forms the lateral malleolus.
