title: [Case-control study on the reconstruction of near distal tendo achillis rupture by suture anchors and traditional steel wire].
abstract: OBJECTIVE
  To compare the curative effects of newly suture anchors and traditional steel wire for the reconstruction of near distal tendo achillis rupture.
  
  
  METHODS
  The clinical data of 56 patients with near distal tendo achillis rupture from June 2007 to February 2011 were retrospectively analyzed. Among 31 patients receiving reconstruction by suture anchors, 22 patients were male and 9 patients were female, with a mean age of 35.5 years (ranging from 16 to 52 years ). Among 25 patients treated with traditional steel wire, 19 patients were male and 6 patients were female, with a mean age of 37.6 years (ranging from 22 to 53 years). The different rehabilitation was conducted for every patient at different times after operation. The position of suture anchor and steel wire were recorded. The clinical data such as operative time, complications of the surgery and the function of stendo achillis were analyzed. The healing of stendo achillis and functional recovery were assessed by Arner-Lindholm standard.
  
  
  RESULTS
  All the patients were followed up with an average during of 24.2 months. There were no intraoperative injuries on blood vessels, nerve and tendon. The average operative time and postoperative complications of suture anchors were lower than there of the traditional steel wire (t = 8.75, P = 0.00; Chi2 = 5.42, P = 0.02). The functional recovery of tendo achillis repaired by suture anchors was better than that in the group of traditional steel wire (Chi2 = 7.65, P = 0.02).
  
  
  CONCLUSIONS
  Compared to the traditional steel wire, suture anchor demonstrate the superior performance on repairing rupture of the near distal tendo achillis, which is a reliable and effective treatment methods.
