- Alternative Names
- Heel cord
- Calcaneal tendon
- Coalescence of the Gastrocnemius and Soleus muscles to form a common tendon
- Plantaris, when present, also inserts into Achilles
- Arises in the middle calf
- Approximately 12-15 cm long
- Thickest, strongest and largest tendon in the human body
- No tendon sheath, just a large highly vascularized paratenon
- Acts as a conduit for the vasculature of the tendon and facilitates tendon gliding between the subcutaneous tissue and posterior fascia
- Kager's fat pad
- Located anterior to Achilles tendon
- Protects blood vessels entering the tendon
- Named after Greek hero Achilles

- Proximal and distal: Recurrent branch of the Posterior Tibial Artery
