Acromioclavicular (AC) dislocation is a common lesion often resulting from a sports injury. Nowadays, treatment is still controversial mainly in grade III lesions according to the Rockwood classification. For most surgically treated AC acute dislocations, treatment is performed with an arthroscopic procedure that anatomically reconstructs the coracoclavicular ligaments. Increasing knowledge about AC joint biomechanics has underlined the importance of its horizontal stability through the superior and inferior AC ligaments. Moreover, the pattern of lesion tends to repeat itself, with the superior AC ligament being torn most frequently from the clavicular side in a peeling fashion. Therefore, the purpose of this note is to describe the technical aspects of additional horizontal stability through superior AC ligament repair using suture anchors.
