Comparison of Short-term Complications Between 2 Methods of Coracoclavicular Ligament Reconstruction: A Multicenter Study

Background:Numerous techniques have been used to treat acromioclavicular (AC) joint dislocation, with anatomic reconstruction of the coracoclavicular (CC) ligaments becoming a popular method of fixation. Anatomic CC ligament reconstruction is commonly performed with cortical fixation buttons (CFBs) or tendon grafts (TGs).Purpose:To report and compare short-term complications associated with AC joint stabilization procedures using CFBs or TGs.Study Design:Cohort study; Level of evidence, 3.Methods:We conducted a retrospective review of the operative treatment of AC joint injuries between April 2007 and January 2013 at 2 institutions. Thirty-eight patients who had undergone a procedure for AC joint instability were evaluated. In these 38 patients with a mean age of 36.2 years, 18 shoulders underwent fixation using the CFB technique and 20 shoulders underwent reconstruction using the TG technique.Results:The overall complication rate was 42.1% (16/38). There were 11 complications in the 18 patients in the CF...
