Initiation and progression of rotator cuff tears due to fatigue loading: a cadaveric study
In a biomechanical model of RC tears induced by fatigue loading, tear initiation was observed approximately 16 mm posterior to the biceps tendon, positioning it further posterior than previously believed. Alterations to the biomechanical properties occur due to tear progression. However, these changes are most severe and significant when tears progress to >100 mm<sup>2</sup> and further progress to >400 mm<sup>2</sup>. These insights provide a potentially clinically relevant definition of tear progression based on biomechanical changes to the supraspinatus tendon.
