Objectives: To evaluate the clinical and radiological outcomes of open anatomical reconstruction of both the coracoclavicular and acromioclavicular ligaments using semitendinosus autograft augmented with a cortical button construct in acute high-grade acromioclavicular joint dislocation. Methods: This retrospective consecutive case series included patients treated for acute Rockwood type III-V acromioclavicular joint dislocation between 2018 and 2023. All patients underwent open anatomical ligament reconstruction using semitendinosus autograft with cortical button augmentation. Clinical outcomes were assessed using the Constant-Murley, Quick Disabilities of the Arm, Shoulder and Hand, and Simple Shoulder Test scores. Radiological evaluation included coracoclavicular distance measurements preoperatively and at final follow-up. Complications and loss of reduction were recorded. Results: Thirteen patients (mean age 35.4+/-8.7 years) were included, with a mean follow-up of 28.6+/-4.3 months. All functional scores significantly improved (p<0.001). The coracoclavicular distance decreased from 17.3 mm to 8.5 mm. Loss of reduction occurred in two patients (15%) but remained asymptomatic. Twelve patients (92%) returned to previous activities. No major complications or revision surgeries were observed. Conclusion: Combined anatomical coracoclavicular and acromioclavicular ligament reconstruction with semitendinosus autograft and cortical button augmentation provides reliable functional recovery, satisfactory radiological stability, and a low complication rate in acute high-grade injuries.
