Return to work after acromioclavicular joint stabilization: a retrospective case control study

BACKGROUND: Considering the epidemiology of acromioclavicular (AC) dislocation related to young and active patients, the impact on working capacity is highly relevant. The purpose of this study was to determine the capacity of work and time to return to work (RTW) after AC joint stabilization. We hypothesized that manual working patients show more restrictions returning to work. METHODS: In this retrospective case series, pre- and posttraumatic working capacity of 54 patients (FU-rate 80.1%, FU time 23, range 18–45 month) stabilized in single TightRope technique was analyzed. Clinical outcome (DASH, Constant-Murley score) and complications were evaluated in addition. RESULTS: Fifty one of 54 patients (94.5%) were returned to work at final follow-up. The median time to return was 13 (5–143) weeks. Manual working patients showed lower RTW-rates (91.2% vs. 100%; p = .151), longer RTW-time (15.5 vs. 6 weeks; p = .008), and more often persistent shoulder symptoms at work (55.9% vs. 5%; p < .001). CONCLUSION: After stabilization of AC joint dislocation, the majority of patients returned to work, needing substantial time to return. Manual working patients required more time and often suffer under persistent symptoms at work.
