“…However, with the re-tear rates of massive rotator cuff tears ranging from 20 to 94% [7,34,46,49], many are considered functionally irreparable rotator cuff tears (FIRCT). The treatment options for a patient with a FIRCT include partial repair [9,17,26,58,91], augmentation or bridging with allografts [4,18,33,62,82,94], superior capsular reconstruction [3,6,22,25,27,51,61,63,65,67,81,84,102], subacromial balloon [90], latissimus dorsi tendon transfer [1, 8, 10, 13, 15, 19, 20, 23, 24, 28, 32, 36, 38, 39, 41, 44, 45, 50, 52, 54-56, 64, 71, 74, 76, 80, 83, 86, 87, 95, 98, 99, 103, 104], lower trapezius tendon transfer [30,31,95,97], and reverse shoulder arthroplasty [11,43,48,77]. Given that the results of partial repair [91] deteriorate with time and the reverse shoulder arthroplasty has been associated with complications [48,96] and functional limitations [2,…”
