Posterior shift of the humeral head in patients with rotator cuff tears and its clinical implication

In some patients with rotator cuff tears, the axial view of magnetic resonance imaging (MRI) shows posterior shift (PS) of the humeral head to the glenoid. This is considered a result of loss of centralization due to loss of rotator cuff function. However, the clinical implication of PS has not been reported. The purpose of this study was to investigate the clinical implication of PS in arthroscopic rotator cuff repair (ARCR). We included consecutive patients who underwent ARCR at our institute and were followed up for at least 1 year.
