Abstract

[Indexed for MEDLINE] 2. Achilles Tendinopathy. Medina Pabón MA(1), Bergman R(2), Naqvi U(3). In: StatPearls [Internet]. Treasure Island (FL): StatPearls Publishing; 2026 Jan–. 2026 Jun 8. Author information: (1)University Industrial Santander / University CES (2)Northwestern University Feinberg School of Medicine (3)Univ. of Miami/Jackson Health System The Achilles tendon, also known as the triceps surae, ranks as the strongest and largest tendon in the human body. This tendon connects the aponeuroses of the gastrocnemius, soleus, and plantaris muscles to the calcaneus bone. A sheath-like structure composed of a single layer of cells surrounds the tendon; this structure is not a true synovial sheath but is known as the paratenon. The paratenon supplies a significant portion of the blood supply to the tendon.  Results from studies identified a hypovascular area susceptible to injury, located approximately 2 to 6 cm proximal to the calcaneal insertion. The Achilles tendon is essential for transmitting force from the calf muscles to the heel during walking and running. Additionally, various factors can contribute to Achilles tendinopathies, with specific locations more commonly affected. This activity explores insertional and noninsertional tendinitis, paratenonitis, and tendon rupture. Copyright © 2026, StatPearls Publishing LLC.
