In a prospective cohort study presented by Accousti et al 1, 56 patients were all managed by 6 weeks of immobilization following rotator cuff repair. When immobilization was removed, 13 patients were considered "stiff" with limited motion, and 43 had "good" passive motion. By one year none of the patients were considered stiff. In the "stiff" group rotator cuff repairs failed in 30%, whereas in the group with "good" motion at six weeks 62% of repairs failed.
