Abstract
Rotator cuff tears are increasing in frequency in the aging population and are a common issue seen by orthopaedic surgeons. In patients with large, multi-tendon rotator cuff tears or retears, treatment can be challenging. Failure rates of up to 90% have been reported for rotator cuff repair (RCR) of large, multi-tendon tears. Biological augmentation has been an area of interest because of the distinctly different biology of the repaired tendon compared with the native tendon. These biological differences affect the ultimate tensile properties of the repair and may contribute to gap formation and the high failure rate of repairs. RCR with allograft augmentation is a technique that shows potential benefit to healing and preventing retears. Arthroscopic augmentation of RCRs can be challenging. The technique described in this Technical Note illustrates a simple and easily reproducible method for augmenting RCRs with human acellular dermal allograft.
