“…6,15,23,24 Chronic tendon deficiency can lead to degradation of tendon tissue quality, fatty infiltration of muscle, and superior migration of the humeral head. 6,10,11,30,31 There have been a number of suggested solutions to this problem, including debridement, 28 partial rotator cuff repair, 4 subscapularis tendon transfer, 2 transfer of the subscapularis and teres minor, 21 transfer of the long head of the triceps, 16 transfer of the teres major, 29 interposition of a biceps tendon autograft, 21 a freeze-dried rotator cuff allograft, 22 and use of synthetic grafts. 26 The results of these procedures have been highly dependent on multiple factors, including the quality of the local tendinous tissue and the mobility or viability of the torn cuff muscles.…”
