Transtendinous Rotator Cuff Tear Repair with Bone Marrow Aspirate Concentrate Dermal Allograft Augmentation.

Rotator cuff tears involving the musculotendinous junction with a significant amount of tendon still attached to the footprint laterally represent a challenging scenario for shoulder arthroscopists. Because of these challenges, adjunctive techniques to bridge tissue gaps may be required, and biologic augmentation may be considered to improve the healing environment. The following technique presents a stepwise approach to accomplishing the dual goals of a stable anatomic repair and biologic augmentation of this difficult pattern of rotator cuff pathology.
