Barcia AM, et al. - This study was intended to systematically examine the literature to ascertain the association between rotator cuff tear presence and size on scapular motion, and if rotator cuff repair restoring normal motion. Using PRISMA guidelines, a systematic review was accomplished to include all studies with biomechanical or clinical outcomes of scapular motion in the presence of rotator cuff tears (RCTs). Researchers enrolled 16 studies including 335 rotator cuff tears. The results of this study exhibited that the scapular motion is abnormal in the presence of an RCT, but the literature is inconsistent regarding a universally affected variable or consistent degree of scapular dysfunction in this setting. Moreover, it remains unknown which variations are adaptive vs. pathologic. According to the findings, understanding the association between rotator cuff tearing and scapular dyskinesis will need better biomechanical models that consider scapular dyskinesis in their design.
