Tarsus: Achilles tendinopathy

Synonym(s): Common calcaneal tendinopathy; Gastrocnemius tendonopathy/enthesopathy; Gastrocnemius tendon avulsion

Contributor(s): Prof Mark Rochat

Introduction

  • Chronic degenerative condition of the tendon.
  • Cause: etiology unknown.
  • Debate exists regarding the role of blood supply in the most commonly affected region of the tendon.  
  • Signs: marked tendon thickening often most prominent near the insertion of the tendon on the calcaneus common.
  • Large breeds most susceptible.
  • Prognosis: generally good to guarded.

Pathogenesis

Etiology

  • Idiopathic but can seemingly present as a traumatic injury following vigorous activity in some cases.
