The talocrural joint is classified as which type of joint?

Explanation:
The key idea is that the ankle joint moves mainly in one plane. The talocrural joint allows dorsiflexion and plantarflexion around a mediolateral axis, so its motion is primarily hinge-like. The distal ends of the tibia and fibula form a mortise that encases the talar trochlea, creating a tight capsule and restricting rotation to that single plane. While it is a synovial joint with a capsule and fluid, the dominant movement pattern classifies it as a hinge joint.
