The Achilles tendon is fibrous tissue that connects the heel to the muscles of the lower leg: the calf muscles. The Achilles tendon joins three muscles: the two heads of the gastrocnemius and the soleus. The gastrocnemius heads arise from the posterior portions of the femoral condyles. The soleus arises from the posterior aspect of the tibia and fibula. The bulk of the Achilles tendon inserts into the posterior superior third of the calcaneus. Some fibers course distally and continue to where portions of the plantar fascia insert into the plantar aspect of the calcaneus. Leg muscles are the most powerful muscle group in the body and the Achilles tendon is the thickest and strongest tendon in the body.
