Editorial Commentary: Don't Pig Out When Selecting a Shoulder, Rotator Cuff Augmentation Graft! Xenografts Are Not the Way to Go.

Porcine xenograft dermal onlay augmentation of rotator cuff repair does not provide improved cuff integrity or provide better clinical outcomes. The retear rate was actually higher in repairs augmented with a porcine xenograft than the control group. Adverse events occurred in 60% of the xenograft patients compared with 40% of the controls. The use of liquid platelet-rich plasma had no discernible impact. A total of 85% of the observed failures with the suture-bridging double-row repair were at the medial cuff (Cho type 2).
