Type: article
Abstract: Background: Acromioclavicular (AC) joint dislocations are found in about 12% of all shoulder injuries, and Rockwood type III–VI lesions frequently need to be treated operatively. Conventionally used fixation techniques have risks of hardware complications and soft tissue disruption. This article compares the clinical and radiologic results of a minimally invasive reconstruction method using a knotless adjustable double loop Endobutton device. Methods: A prospective observational study was performed from December 2022 to December 2023 on five patients aged 20–40 years with acute Rockwood type III–V AC dislocations. Percutaneous coracoclavicular reconstruction with a double loop Endobutton system was performed in the patients. Postoperative rehabilitation consisted of passive range of motion at two weeks and return to full activity by 3–4 months. Outcomes were measured clinically with the Constant and UCLA scores, and radiologically to assess reduction maintenance. Results: All patients showed progressive improvement in shoulder function, with Constant and UCLA scores of 87 and 31, respectively, at one-year follow-up. No redislocation, suture loosening, or infection was noted. One patient had an implant cut-out without compromising stability or revision requirement. 1 patient had residual subluxation.The technique afforded consistent reduction, minimal soft tissue trauma, and stable fixation during follow-up. Conclusion: The knotless adjustable double loop Endobutton method is a secure and effective means of treating acute AC joint dislocations. It reduces soft tissue damage, preserves long-term reduction, and facilitates early functional recovery with low complication rates.
