title: Can a double-row anchorage technique improve tendon healing in arthroscopic rotator cuff repair?: A prospective, nonrandomized, comparative study of double-row and single-row anchorage techniques with computed tomographic arthrography tendon healing assessment.
abstract: BACKGROUND
  Increasing the rate of watertight tendon healing has been suggested as an important criterion for optimizing clinical results in rotator cuff arthroscopic repair.
  
  
  OBJECTIVE
  A double-row anchorage technique for rotator cuff repair will produce better clinical results and a better rate of tendon healing than a single-row technique.
  
  
  METHODS
  Cohort study; Level of evidence, 2.
  
  
  METHODS
  We compared 31 patients undergoing surgery with a double-row anchorage technique using Panalok anchors and Cuff Tack anchors and 35 patients with rotator cuff tear undergoing surgery with a single-row anchorage arthroscopic technique using Panalok anchors. We compared pre- and postoperative Constant score and tendon healing, as evaluated by computed tomographic arthrography 6 months after surgery, in these 2 groups.
  
  
  RESULTS
  The Constant score increased significantly in both groups, with no difference between the 2 groups (P = .4). Rotator cuff healing was judged anatomic in 19 patients with double-row anchorage and in 14 patients with single-row anchorage; this difference between the groups was significant (P = .03).
  
  
  CONCLUSIONS
  In this first study comparing double- and single-row anchorage techniques, we found no significant difference in clinical results, but tendon healing rates were better with the double-row anchorage. Improvements in the double-row technique might lead to better clinical and tendon healing results.
