Since 1982, the authors have progressively settled a technique to repair the calcaneal tendon, the result of which is a percutaneous tenorraphy exclusively used for more than 2 years. Their study includes 28 cases between 1989 and 1992, with an average post operative time of 15.6 months. The technique is fully described, its aim was to restore a normal length of the ruptured tendon in placing together the 2 tendinous ends during the required time to obtain natural regeneration of the Achilles tendon. It reduces the theoric immobilization time, makes rehabilitation easier as well as the return to sportive and professional activities. The suture was percutaneously made with a special material: A Dacron yarn with a 5 mm wide hook set on a 12 long flexible needle. The results were globally good and only very few complications were observed.
