Arthroscopic-Assisted Triple-Bundle Reconstruction for Acromioclavicular Joint Dislocation.

Abstract

This article describes a practical technique for treating acute and chronic acromioclavicular joint dislocations. With the aid of intraoperative arthroscopy, tunnels were drilled on the clavicle and coracoid process, and Tightrope and Endobutton devices were introduced to anatomically reconstruct the conoid and trapezoid ligaments, respectively. Subsequently, the acromioclavicular ligaments were reconstructed using wire ties, to restore the sagittal and axial stability of the acromioclavicular joint as much as possible through the reconstruction of the triple bundle. Its main advantages were anatomical reconstruction, simultaneous restoration of axial stability, and reduction of the occurrence of redislocations and iatrogenic fractures.
