AB  - BACKGROUND: Acromioclavicular (AC) joint separation is a common injury. The 
      anatomic coracoclavicular ligament reconstruction (ACCR) technique is a viable 
      treatment option, designed to restore the native joint anatomy. PURPOSE: To 
      evaluate the clinical and radiographic outcomes of patients undergoing ACCR for 
      the treatment of type III and V AC joint injuries with a minimum 2-year 
      follow-up. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: A 
      retrospective chart review was performed on prospectively collected data. 
      Patients who underwent ACCR for type III or V AC joint injuries between January 
      2003 and December 2015 were analyzed. Clinical outcome measures included the 
      American Shoulder and Elbow Surgeons (ASES) score, Rowe score, Simple Shoulder 
      Test (SST), and Constant-Murley (CM) score. To determine the clinical relevance 
      of the ASES score, the minimal clinically important difference (MCID), 
      substantial clinical benefit (SCB), and patient acceptable symptomatic state 
      (PASS) were used. The pre- and postoperative coracoclavicular distance (CCD) and 
      side-to-side difference in the CCD were measured for radiographic analysis. 
      RESULTS: A total of 43 patients (22 acute, 21 chronic) were included in the 
      study. The mean patient age was 43.4 +/- 11.4 years, with a mean follow-up of 3.4 
      years (range, 2.0-7.5 years). With regard to the ASES score, 92% of patients 
      achieved the MCID, 81% achieved the SCB, and 49% reached or exceeded the PASS. 
      There was no significant difference when stratifying by type (III vs V) or 
      chronicity (acute vs chronic) of injury (both P > .05). The Rowe score improved 
      from 66.6 +/- 15.9 preoperatively to 88.6 +/- 12.3 postoperatively, the CM score from 
      61.6 +/- 18.8 to 87.4 +/- 15.1, and the SST score from 6.2 +/- 3.6 to 9.4 +/- 3.7 (all P 
      < .001). The postoperative side-to-side difference in the CCD was 3.1 +/- 2.7 mm, 
      with type III injuries (2.4 +/- 1.9 mm) showing significantly lower measurements 
      compared with type V (4.2 +/- 3.4 mm) (P = .02). No significant trend was found 
      between joint reduction and the improvement in clinical outcomes (P > .05). 
      CONCLUSION: Patients undergoing ACCR for acute and chronic type III and V AC 
      joint injuries maintained significant improvement in clinical and radiographic 
      outcomes at a minimum 2-year follow-up. Additionally, 81% of patients reached the 
      SCB after surgical reconstruction.
