The superior surface of the body of the talus is covered with articular cartilage for articulation with the inferior surface of the tibia. This articular surface is continuous with the articular surfaces of the medial and lateral aspects of the talus. The superior surface is somewhat wider anteriorly than posteriorly. It is convex anteroposteriorly and slightly concave mediolaterally, corresponding to the sellar surface of the inferior end of the tibia mentioned previously. In this sense, the superior talar articular surface is trochlear, or pulley-like, and is often referred to as the trochlea.
