Brief Summary:
The purpose of this study is to estimate the effective of two suture methods in the treatment of Achilles rupture.

Condition or disease Intervention/treatment Phase
Achilles Tendon Rupture Procedure: sewed indirectly Procedure: sewed directly Not Applicable

Detailed Description:
Achilles tendon rupture is one of the most common tendon injuries in the adult population. The incidence of this injury is increasing as aging adults continue their participation in high-demand sports. Although the impact of an Achilles tendon rupture is substantial, often resulting in prolonged disability and rehabilitation. Studies have showed that the operation treatment of acute Achilles tendon ruptures had some advantages. But the rebuild of blood supply was not involved in previous studies. And the epitenon of tendon is the interior layer, closest to the endotenons which contains the vascular supply. Main difference of two suture methods were if the epitenon was repaired and sewed indirectly or unrepaired and sewed directly.

    Calf circumference was measured at six weeks after surgery.

  2. Complications [ Time Frame: six months ]
    Infection and rerupture at six month after surgery.
