Relationship between the Hamada Grade and underlying pathological conditions in the rotator cuff and long head of biceps in symptomatic patients with rotator cuff tears

Development of a novel animal model of rotator cuff tear arthropathy replicating clinical features of progressive osteoarthritis with subchondral bone collapse

Therefore, combined destruction of the superior capsule and the LHB tendon is likely to be the crucial event allowing CTA to progress.…”
