A comparison of double Endobutton and triple Endobutton techniques for acute acromioclavicular joint dislocation

80 patients with moderate to severe acromioclavicular joint dislocation scheduled for coracoclavicular ligament reconstruction were randomized to either triple Endobutton fixation or double Endobutton fixation. The purpose of this study was to determine if triple Endobutton fixation was beneficial over double Endobutton fixation with respect to surgical outcomes, patient-reported functional outcomes, and radiographic outcomes over a minimum 12-month follow-up. Results demonstrated no significant differences between groups for any outcome measure, with the exception of significantly higher hospital costs in the triple Endobutton group compared to double Endobutton group.
