Outcomes of acromioclavicular joint dislocation using tightrope arthroscopy

Abstract

Background: Based on different treatment outcomes and different treatment methods for acromioclavicular dislocation, we decided to evaluate the treatment outcomes of acromioclavicular joint dislocation using tightrope arthroscopy. Methods: This retrospective cross-sectional study was performed on patients with acromioclavicular joint dislocation referred to Alzahra Hospital in Isfahan and Abadan-Iran from 2015 to 2017. Information that was assessed included age, sex, type of dislocation (Figure 1), duration of injury, cause of injury, complications such as osteoarthritis, changes in the distance between the joints, as well as the American Shoulder and Elbow Surgeons Shoulder Score (ASES) were collected after 6 months of surgery. Results: There was a significant relationship between horizontal change instability and type of injury that 9 cases (60) of type 5 of injury and 0 of type 3 had horizontal change instability (P=0.01). There was a reverse significant correlation between ASES score and duration of injury (r=-0.58, P=0.01). Conclusion: Acromioclavicular joint dislocations could successfully be treated with the TightRope system. We also showed that patient's pain and functions are diversely correlated with injury durations.
