This prospective cohort followed 22 patients after arthroscopic repair of large (>3 cm) and massive rotator cuff tears. Serial ultrasound at 7 time points over 2 years mapped exactly when repairs fail. It asks whether retears occur early (mechanical) or late (biologic), and whether they worsen outcomes.
The clinical takeaway is a timing rule: if a large or massive cuff repair is going to fail structurally, it almost always does so within the first 3 months, and essentially never after 6 months.
That reframes how you think about failure. The authors split it into two mechanisms. Early failure (<3 months) is mechanical, most likely the suture pulling through degenerative tendon. Later failure (>3 months) is biologic, meaning the construct held but the enthesis never healed.
Because two failures happened while patients were still immobilized, you cannot blame overaggressive therapy alone. This argues for secure intraoperative fixation and attention to tissue quality at the suture-tendon interface.
For boards, remember that intact repairs trend toward better outcomes, but patients frequently improve symptomatically even after retear, likely from partial restoration of force couples, bursectomy, and rehabilitation.
