Individualized Treatment for Acute Achilles Tendon Rupture Based on Barfod's Ultrasonographic Length Measure - a Randomized Controlled Trial
In Brief
A clinical study evaluating Individualized treatment of Acute Achilles tendon rupture., Non-operative treatment, and 1 other intervention for Achilles Tendon Rupture. Completed, enrolled 300 participants across 4 sites.
Detailed Summary
To asses the functional outcome after individualized treatment of acute achilles tendon rupture. The treatment is individualizes on the basis of ultrasonographic status of tendon overlap and Barfod's Ultrasonographic length measure. Patients are allocated for operative treatment if there the tendon overlap is less than 25 % or the tendon is elongated with 7% or more compared to the healthy, contralateral achilles tendon. The study includes two control groups of non-operative and operative treatment.

Timeline
Interventions
The most proximal border of the calcaneus and the most distal point of the musculotendinous junction of the Achilles tendon and 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 and consist of the free tendon and the fascia \[1\]. 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. The cut-off at 7% elongation is determined for 75% sensitivity and 65% specificity of elongation.
