Biologic Augmentation of Arthroscopic Rotator Cuff Repair Using Minced Autologous Subacromial Bursa
Neel Pancholi, James M. Gregory
Abstract
Failure of rotator cuff repair surgery can be attributed to a variety of factors, including insufficient biologic environment to support healing. The subacromial bursal tissue has been shown to have a reservoir of mesenchymal stem cells and is a potential source for biologic augmentation during rotator cuff repair. We have developed a technique to capture the subacromial bursal tissue during subacromial bursectomy and then reimplant the tissue on the bursal surface of the rotator cuff tendon after rotator cuff repair. Our goal is to describe our technique of subacromial tissue collection and reimplantation that obviates the need of suturing a whole sleeve of bursal tissue while improving cell yield for rotator cuff healing.
