Which bone located in the lower leg contributes to the ankle joint with the tibia?

Explanation:
The main idea is how the bones of the lower leg contribute to the ankle joint alongside the tibia. The fibula is the slender bone on the outside of the leg. At the ankle, its distal end forms the lateral malleolus, which articulates with the talus and pairs with the tibia at the distal tibiofibular joint to complete the ankle mortise and provide lateral stability. This is why the fibula, not the tibia itself, is the other bone that contributes to forming the ankle joint with the tibia. The patella is a knee cap, and the femur is a thigh bone, so they aren’t directly involved in forming the ankle joint with the tibia.
