Subscapularis re-tears associated with preoperative advanced fatty infiltration and greater subscapularis involvement, leading to inferior functional outcomes and decreased acromiohumeral distance

ConclusionAfter a minimum 5-year follow-up after arthroscopic partial repair of anterosuperior MRCT, subscapularis re-tear was identified in 35% of patients (20/57) on early postoperative follow-up MRA/CTA. The subscapularis re-tear group exhibited more preoperative advanced fatty infiltration and greater extents of subscapularis involvement, which led to statistically inferior functional outcomes and decreased acromiohumeral distance at final follow-up. Nonetheless, in terms of a minimal clinically important difference, substantial clinical benefit, and patient-acceptable symptomatic state for clinical significance, there were no significant differences between the groups.Level of evidenceIII.
