Primary End-end Tendo-Achilles Repair for Defect of 7 cm: A Case Report with Literature Review

Achilles tendon is the thickest and strongest tendon and is only found in humans; it evolved as a result of bipedal gait. 1 Achilles is a common tendinous lesion affecting 18 in 100,000. The ability to run is a feature present in humans where the spring-like tendon reduces the cost of energy during transport. Tendo-Achilles lesions >4 weeks are termed chronic lesions. Causes of chronic Achilles tendon lesion include neglected spontaneous rupture and failed repair. Spontaneous rupture occurs at 2-6 cm proximal to insertion because of the small cross-section of the tendon and limited vascular supply.
