ankle joint
Ankle Joint
Ankle joints are complex mechanisms that play important roles in allowing movement in the lower extremities and providing stability. Several ligaments support the ankle's overall stability by joining the bones and ensuring optimal joint function. The anterior talofibular ligament (ATFL), posterior talofibular ligament (PTFL), and calcaneofibular ligament (CFL) comprise the lateral (outside) portion of the ankle joint. These ligaments contribute lateral support to the ankle by attaching the talus…
