Return to Work After Primary Rotator Cuff Repair: A Systematic Review and Meta-analysis.

BACKGROUND

Rotator cuff tears are a prevalent pathology in injured workers, causing significant economic ramifications and time away from work. To date, published articles on work outcomes after rotator cuff repair have not been cumulatively assessed and analyzed.

PURPOSE

To systematically review reports on return to work after rotator cuff repair and perform a meta-analysis on factors associated with improved work outcomes.

STUDY DESIGN

Systematic review and meta-analysis; Level of evidence, 4.

METHODS

A systematic review of return-to-work investigations was performed using PubMed, Embase, and the Cochrane Database of Systematic Reviews in accordance with the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Individual studies reporting rates of return to previous work with level of evidence 1 to 4 were independently screened by 2 authors for inclusion, and study quality was assessed using the Methodologic Index for Non-randomized Studies and Newcastle-Ottawa Scale. Work outcome data were synthesized and analyzed using random effects modeling to identify differences in rates of return to previous work as a function of operative technique, work intensity, and workers' compensation status.

RESULTS

Thirteen retrospective investigations comprising 1224 patients who underwent rotator cuff repair met inclusion criteria for this investigation. Across all investigations, a weighted average of 62.3% of patients returned to previous level of work at 8.15 ± 2.7 months (mean ± SD) after surgery. Based on random effects modeling, higher rates of return to previous work were identified with decreasing work intensity ( < .001), while rates were similar between open and arthroscopic repair technique ( = .418) and between workers' compensation and non-workers' compensation cohorts ( = .089). All shoulder pain and functional outcome assessments demonstrated significant improvements at final follow-up when compared with baseline across all investigations.

CONCLUSION

The majority of injured workers undergoing rotator cuff repair return to previous work at approximately 8 months after surgery. Despite this, >35% of patients are unable to return to their previous work level after their repair procedure. Similar rates of return to work can be anticipated regardless of workers' compensation status and operative technique, while patients in occupations with higher physical intensity experience inferior work outcomes.
