Description: Achilles tendon is a common tendon shared by the gastrocnemius and soleus muscles. It is the thickest tendon in the body, originated in the middle of the calf and extends down the back of the leg to the heel

Functions: It transmits power from the calf muscles to the heel, enabling plantar flexion (pointing the foot down). This is crucial for pushing off during walking, running, and jumping

Description: It is a Y-shaped band of fascia located on the anterior aspect of the ankle, acting as a crucial restraint for the anterior ankle tendons

Functions:

Secure tendons: It holds the extensor tendons in place as they pass over the ankle joint

Prevent dislocation: It helps to prevent the tendons from dislocating or subluxating during movement

Reinforce ankle stability: It can be used to reinforce the repair of the anterior talofibular ligament in lateral ankle instability, especially in the Broström-Gould procedure

Description: A fibrous band of deep fascia that helps stabilize the tendons of the peroneal muscles (peroneus longus and brevis) as they cross the lateral side of the ankle

Functions: It helps to keep the tendons of the peroneal muscles (peroneus longus and brevis) from slipping out of their groove (retromalleolar groove) as the ankle moves

Insertion: It inserted into dorsum of the shaft of the 5th metatarsal bone

Description: It is the large bony prominence on the medial side of the ankle

Functions: It forms the medial side of the ankle joint; it articulates with the medial surface of the talus. It provides attachment points for the deltoid ligament (also known as the medial collateral ligament)

Description: It is an enlarged distal end of the fibula

Functions: It forms the lateral side of the ankle joint; it articulates with the lateral surface of the talus. It provides attachment points for the lateral collateral ligaments
