Yamanaka and Matsumoto used serial arthrography to track the natural history of 40 articular-surface (joint-side) partial rotator cuff tears managed conservatively over a mean of 412 days. The study asks a simple but clinically vital question: do these tears heal, stabilize, or progress?
When you see a joint-side partial rotator cuff tear, especially in a patient over 60 with a large, atraumatic lesion, expect progression — 28% will become full-thickness tears and 80% will worsen structurally even if symptoms improve modestly.
Don't let a rising symptom score reassure you that the tear is stable.
