Achilles tendon rupture.

Abstract

The Achilles tendon (AT) is the largest tendon in the human body, but it is also the one that frequently undergoes a complete subcutaneous tear. Men are more frequently affected than women, in particular between 30–40 years old. An AT tear is usually the end result of an asymptomatic process of failed heling typical of tendinopathy. The diagnosis of acute tear of the AT is clinical, based on careful history taking and detailed clinical examination. Operative management of acute AT ruptures provides lower re-rupture rate, early functional treatment, less calf atrophy, and better functional results, in particular in athletes. Minimally invasive Achilles tendon repair provides many advantages and should be considered in young and active patients. Simple parameters as single-legged concentric strengthening, range of motion, and calf circumference can be used to predict the ability to return to activity. On the basis of current evidence-based studies, the routine use of PRP to improve tendon AT healing is not recommended.
