The term 'rotator cuff tear' can refer to anything from a small gap in the tendon from use and wear
to a larger tear involving the supraspinatus tendon from an old injury with what appears to be sufficient quality and quantity of tissue for a robust repair
to a long-standing large tear without enough tissue for a repair
to a massive tear of the entire rotator cuff
to tears with deterioration of the joint surface of the humeral head
to full on rotator cuff tear arthropathy without or with collapse of the humeral head and essentially no rotator cuff remaining.
