Among the many joints in the human body, one of the most integral is the talocrural region, which most people know as the ankle joint. This connection between the foot and the lower leg carries out many useful functions for the leg and the body as a whole. Though most people refer to the area as a singular joint, the ankle bones actually form two or three joints, depending on how experts classify them.


1. Talus

Many bones can be viewed as “ankle bones,” but the only true ankle bone is the talus. Technically, the talus belongs to the tarsus group of foot bones, but it is unique in several ways. Unlike most other bones, the talus does not attach to any muscles. As such, its position is entirely reliant on the surrounding bones. Additionally, in comparison to other bones, it is covered in one of the highest percentages of articular cartilage.
