Preoperative clinical and imaging features also predict the likelihood of success of a rotator cuff tendon repair and are important to recognize. In patients with irreparable rotator cuff tears and relatively preserved glenohumeral cartilage, various joint-preserving surgical options are available and seen increasingly in clinical practice.The acceptable range of postoperative imaging findings correlating with a functionally intact rotator cuff repaired tendon, and MRI findings that are either suggestive of or definitive for rotator cuff tendon repair failure are discussed in detail, with attention to the Sugaya classification. Ancillary features, such as progressive retraction of the myotendinous junction and the degree of muscle fatty atrophy, can be used as problem-solving tools in cases equivocal for rotator cuff retear.
