Achilles Tendon Elongation and Gait Pattern After Rupture.

The most proximal border of the calcaneus and the most distal point of the musculotendinous junction of the medial gastrocnemius muscle is identified and marked on the skin. These two points on the un-injured leg defines the original length of the total Achilles tendon \[1\]. The difference in length between the injure and the un-injured leg determines elongation for the ruptured Achilles tendon. The relative elongation of the ruptured tendon together with overlap of the tendon ends on the cross-sectional area determines the treatment for the patients receiving individualized treatment: 1) patients with 0-6% elongation of the tendon and a minimum of 25% tendon are treated non-operatively 2) patients with 7% elongation or more or less than 25% tendon overlap are treated operatively.
