Functional and radiographic outcomes after allograft anatomic coracoclavicular ligament reconstruction

Abstract

Introduction: Acromioclavicular joint dislocation is a commonly encountered shoulder injury. Various surgical methods are available for the treatment of complete AC Joint dislocation, however, optimal surgical treatment is still controversial. The purpose of this study was to evaluate the functional and radiographic outcomes after allograft anatomic coracoclavicular ligament reconstruction.Materials and Methods: 18 patients with grade III to V AC joint disruptions underwent allograft anatomic coracoclavicular ligament reconstruction. Functional and radiographic outcomes were assessed using DASH score and Constant score.Results: The mean coracoclavicular (CC) distance decreased from 16.98±3.20 mm (pre-operative) to 8.93±1.25 mm (at final follow-up). Based on Constant Scores there were 10 (50.56%) excellent outcomes, 4(22.22%) good outcomes, 2(11.11%) fair outcomes, and 2(11.11%) poor outcomes.Conclusion: Allograft anatomic coracoclavicular ligament reconstruction results in generally good-toexcellent outcomes at the final follow-up.
