Editorial Commentary: Bio-inductive Collagen Implant to Augment Repair of Rotator Cuff Tears May Be Less Effective for Massive Tears and Revision Repair.

To improve healing after rotator cuff repair, synthetic, allograft, and dermal xenograft patches have been shown to significantly improve strength and load. Recent research has shown that a bio-inductive bovine collagen implant results in improvement in healing in partial-thickness, small, medium, and even large tears, but thus far, repair of massive and revision tears with augmentation is no better than repair alone. Optimizing these challenging repairs remains difficult and elusive.
