Pre\u2010operative MRI images were evaluated by a fellowship\u2010trained shoulder surgeon, blinded to the surgical outcome. Stump location, tear dimension in the coronal and sagittal plane, fatty infiltration, muscle atrophy (occupation ratio, tangent sign), and superior migration of the humeral head (acromion\u2013humeral distance, inferior glenohumeral distance, and best\u2010fit humeral circle technique) were assessed as the predictors of repair.

On MRI, reparability was associated with increased medial\u2013lateral (ML) tear size (<jats:italic>p<\/jats:italic> = 0.003), but not increased AP tear size (n.s.). An association was seen between partial repair and tendon retraction to or beyond the glenoid (<jats:italic>p<\/jats:italic> = 0.0005), positive tangent sign (<jats:italic>p<\/jats:italic> = 0.04), advanced supraspinatus fatty infiltration in isolation (<jats:italic>p<\/jats:italic> = 0.046), combined advanced supraspinatus and infraspinatus fatty infiltration (<jats:italic>p<\/jats:italic> = 0.04), and superior migration of the humeral head as measured by the inferior glenohumeral distance only (<jats:italic>p<\/jats:italic> = 0.004).
