The Achilles tendon is the largest tendon in the body, connecting the gastrocnemius and soleus muscles to the calcaneus. It contains both a retrocalcanean bursa anterior to the tendon when it is inserted and a larger and more superficial subcutaneous bursa posterior to the tendon. Although Achilles superficial bursitis is not related to a specific injury, it is usually due to repetitive stress on the insertion of the tendon on the calcaneus. There are several causes for this, including a sudden increase in exercise regimen, tense gastrocnemius muscles, and calcaneal spurs. In addition, it can be seen in active middle-aged people who play recreational sports or who suddenly increase their intensity or training time. Treatments include physical therapy, strengthening exercises, anti-inflammatory drugs, orthotics, heel lift and activity modification.
