title: Comparison of the Tight Rope Technique and Clavicular Hook Plate for the Treatment of Rockwood Type III Acromioclavicular Joint Dislocation.
abstract: OBJECTIVE
  Acromioclavicular joint dislocation is one of the most common shoulder problems and may lead to instability or degenerative changes. The aim of this study was to compare the clinical outcomes of the Tight Rope system and clavicular hook plate for Rockwood type III acromioclavicular joint dislocation in adults.
  
  
  METHODS
  This was a prospective, randomized study in a hospital setting. From January 2012 to December 2014, 69 patients with type III injury were reviewed. Patients were randomly divided into two groups: Group A was treated using the TightRope system and Group B with the clavicular hook plate. All participants were followed up for 12 months. Clinical outcomes, radiological results and postoperative complications were recorded.
  
  
  RESULTS
  The length of incision was significantly shorter in Goup A than that in Group B. The blood loss of surgery was significantly less in the Group A. Significant difference could be found between the two groups regarding the Visual Analogue Scale scores one day after surgery, at the 3 and 12 months follow-up. There were no differences according to the improvement of the Constant-Murley score and the coracoclavicular distance between the groups.
  
  
  CONCLUSIONS
  The two groups have similar clinical and radiological outcomes. Both treatments could relieve the pain of dislocation, improve the function of Acromioclavicular joint and rectify the coracoclavicular distance measured in plain films. However, the TightRope system exhibited some advantages in terms of length of incision, blood loss of surgery, the pain postoperatively and no need for a second surgery.
