Human Dermal Allograft Patch Augmentation of Degenerate Rotator Cuff Tendon Using a Single Lateral-Row Technique

Bioactive fiber-reinforced hydrogel to tailor cell microenvironment for structural and functional regeneration of myotendinous junction

“…To date, surgical suturing and conventional therapy are the mainstream clinical treatment approaches for MTJ injuries. However, these treatments often induce scar tissue formation and suture cut-through, lacking the native structure and enough mechanical properties required for functional maintenance, consequently leading to retear and failed MTJ reconstruction (3)(4)(5). A few previous studies have attempted to construct mechanically, structurally, and biochemically biomimetic scaffolds for MTJ repair and regeneration.…”

“…Current clinical treatments for MTJ injuries include conservative treatments such as nonsteroidal anti-inflammatory drugs and physical therapy, as well as surgical intervention using various suturing technologies. However, several limitations impede their effectiveness, including the following: (i) the formation of scar tissue leading to insufficient mechanical strength, contributing to a high recurrence rate after treatment ( 3 , 4 ); (ii) the suture cut-through at or near MTJ injury, often resulting in failed MTJ reconstruction ( 5 , 6 ); and (iii) challenging repair of large MTJ defects, especially in cases where muscle and tendon retract after injuries ( 5 , 7 ). Consequently, current interventions are unable to promote both the structural and functional repair of MTJ, necessitating the development of promising strategies for high-quality MTJ regeneration.…”

Arthroscopic Incomplete Rotator Cuff Repair With Patch Augmentation Using Acellular Dermal Matrix Allograft

“…However, ARCR with patch augmentation is technically challenging due to several difficulties, such as delivering the patch, securing it in the proper location, managing multiple sutures, and extended surgical time. Although several articles have reported relatively simplified techniques, 16 , 17 , 18 , 19 , 20 , 21 we report a systematic and consistent surgical technique to achieve a firm fixation of the patch on the incompletely repaired tendon ( Table 2 ). Thus, this article describes a combined technique of incomplete repair 3 and patch augmentation using the ADM allograft.…”
