The Joint: Bones, Tendons, Ligaments, and Muscles
The talocrual joint is made up of three main bones.
1. The Tibia
2. The Fibula
3. The Talus
The weight of your body is transferred from the tiba to the talus. This allows weight to be distributed either anteriorly or posteriorly throughout the foot.

Ligaments of the Ankle
The ligaments of the ankle are sorted into two categories
1. Medial Collateral Ligaments: Prevent abduction, limit plantar flexion and dorsiflexion
Deltoid ligament: Supports medial side of ankle joint.
2. Lateral Collateral Ligaments:
Limit plantar flexion, resist adduction, limit dorsi flexion
Anterior talofibular ligament (ATFL): prevents foot from sliding forward too far in relation to the shin. It is the most commonly injured ligament, mainly from inversion injuries. It is also the weakest of the lateral ligaments. It also limits plantar flexion of the joint.
Calcaneofibular ligament (CFL): Attaches fibula to the calcaneus bone. Resists adduction.
Posterior talofibular ligament (PTFL): Strongest of the lateral ligaments. Limits dorsiflexion.

Tendons of the Ankle
Achilles tendon: Attaches the calf muscles to the calcaneus, most important muscles for running, jumping, walking etc. Also allows the action of raising up onto toes.
Posterior tibial tendon: Allows the foot to be turned inward and also supports the arch of the foot.
The Anterior tibial tendon: Allows the action of raising the foot.

Muscles of the Ankle
Major muscles :
Gastrocnemius: plantar flexes the foot at the ankle
Soleus: Involved in standing and walking
