<B>Background:</B> There is seldom report regarding to the relationship between trauma and rotator cuff tear.<BR><B>Methods:</B> Patients who underwent rotator cuff repair between Sep. 2008 and Mar. 2011 were included in this study. All patients were evaluated by JOA score before and 1-year operation after. 65 patients, 67 shoulders were included. Age, trauma history, the period they had been symptomatic and JOA score were evaluated. These patients were divided into three groups: TR group as those who became symptomatic after direct trauma, TE group as those who became symptomatic after trifling episode, NT group as those who had no trauma.<BR>There were 14 patients (14 shoulders) who abducted actively below 90 degrees at first referral. Same evaluation was done separately for all patients.<BR><B>Results:</B> JOA score was improved significantly after operation (p < 0.001). In all patients, there was no significant difference between three groups in age and JOA score before operation. Although there was significant difference between three groups in the symptomatic period, there was no significant difference between them in JOA score after operation.<BR>In the patients who abducted below 90 degrees, the patients in NT group tended to be symptomatic for a longer period. The patients in TR and TE group tended to have a better JOA score after operation than those in NT group regardless of rotator cuff size.<BR><B>Discussion:</B> The trauma history itself didn't affect the outcome of the rotator cuff repair. However, active abduction was impaired after trauma, good results were expected.
