Background: Erosion on the undersurface of the acromion has been recently reported as complication after cuff repair using suture anchors, however its incidence is varied. Although we had lower a rate of these complications than those of other studies, postoperative MRIs often show subacromial effusion. The purpose of this study was to determine clinical significances of the subacromial effusion. Methods: Ninety-two shoulders from 88 patients were included in this study. The average age at surgery was 66.8 years old. There were 9 small, 63 medium, 18 large, and 2 massive tears. Subacromial effusion was noted in 50 shoulders (54.3%), acromial bony erosion was found in 17 (18.4%) on MRI 12 months after surgery. Patients were divided into two groups according to the presence or absence of subacromial erosion; SE(+) and SE(-). Results: There was no significant difference in age of the patients, size of the tear, duration of operation, and number of anchors or sutures used. Pre and postoperative JOA score was similar in the two groups. Active flexion was significantly better in SE(+) at six months after surgery. The incidence of acromial erosion was significantly higher in SE(+) when compared with SE(-). Conclusion: Subacromial effusion was found in more than half of the cases, which did not affect clinical outcomes. Subacromial effusion should be followed carefully, since these may closely correlate with acromial erosion.
