Primary Outcome Measures:
  • Blood supply condition [ Time Frame: six weeks ]
    Blood supply was estimated by ultrasonic contrast at six weeks after surgery.

Secondary Outcome Measures:
  • Calf circumference [ Time Frame: six weeks ]
    Calf circumference was measured at six weeks after surgery.

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

Estimated Study Completion Date: June 2013
Estimated Primary Completion Date: May 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions

Procedure: sewed directly
The epitenon was unrepaired and sewed directly.

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.
