[Injuries of the acromioclavicular joint in athletes]

Acromioclavicular joint (ACJ) dislocation is a common injury to the shoulder girdle, especially in contact and high velocity sports. Besides the severity of the injury, and particularly in competitive and elite athletes and the type of sports, individual career plans and in and out of season injuries have to be taken into account when advising treatment for athletes. Conservative treatment is reserved for low-grade dislocations and in-season athletes. The aim is fast pain relief and a safe return to competitive sport. High-grade ACJ dislocations in athletes should be treated surgically. Arthroscopic and arthroscopically-assisted techniques can offer a lower risk of infection, a higher patient acceptance in terms of cosmetic perspectives and the potential to treat concomitant glenohumeral lesions and may avoid potential disadvantages of open techniques, such as secondary obligatory implant removal and extensive soft tissue preparation with a relevant approach morbidity.
