Advantages and Disadvantages of Arthroscopic Rotator Cuff Repair Using Minced Autologous Subacromial Bursa

Advantages	Disadvantages
Most surgeons have comfort performing a subacromial bursectomy.	Requires some time for surgical assistant to transfer bursal tissue to syringe.
Tissue is minced which improves MSC yield.	Must have a dry shoulder at time of reimplantation of bursal tissue.
No additional device or suture is required for fixation.	Requires use of a graft collection device.
Can be used with any type of rotator cuff repair.	Unproven efficacy.
Can be used with any type of rotator cuff repair.
Less costly than other forms of biologic augmentation.	Still adds cost.
Applied on bursal surface of tendon, so can be used in conjunction with tendon/bone interface biologics or marrow stimulation.	No evidence that tissue remains where it is placed.

MSC, mesenchymal stem cells.
