title: Arthroscopic reconstruction of the acromioclavicular joint disruption: surgical technique and preliminary results.
abstract: BACKGROUND
  Numerous operative procedures have been described for the reconstruction of acromioclavicular joint separation; however, the arthroscopic reconstruction has been rarely reported. Therefore, our objective was to propose a new technique of arthroscopic acromioclavicular joint surgery and to evaluate the preliminary results.
  
  
  METHODS
  Thirteen patients with a mean follow-up of 18 months underwent the arthroscopic acromioclavicular joint reconstruction using suture anchors and small titanium plate. The average age was 40.2 years (range 23-54 years). The shoulders were evaluated using Constant score and radiographs. The indications for surgery included acromioclavicular joint dislocation Rockwood type IV-V.
  
  
  RESULTS
  Twelve patients returned to their work without pain within 3 months after operation. The average Constant score at last follow-up was 95. Postoperative radiographs confirmed anatomic reduction in ten patients, residual subluxation in two patients and redislocation of the joint in one patient. One patient had radiographic evidence of coracoclavicular ossification. All patients but one were satisfied with results and cosmetic appearance.
  
  
  CONCLUSIONS
  Considering its less morbidity, excellent cosmesis, no need of hardware removal, and minimal complications from breakage or migration of metal implants, this new technique offers an attractive alternative in acromioclavicular joint stabilization.
