Key Points

The review aims to evaluate the histologic and biochemical impacts of scaffold augmentation in rotator cuff repairs and compare different materials.
Conducted a PRISMA-guided search of PubMed, Scopus, and Embase for relevant studies.
Included forty-two studies focusing on histologic and biochemical outcomes following patch augmentation.
Excluded biomechanical or imaging outcome studies and in vitro or cadaveric models.
Dermal matrix patches improved neovascularization and collagen synthesis, but resulted in incomplete fibrocartilage formation.
ECM-derived patches led to better collagen alignment but showed some inflammation.
Synthetic polymers produced dense type 1 collagen with variable immune responses.
Biologically augmented scaffolds exhibited the highest collagen density and minimal macrophage infiltration.
Demineralized bone matrix achieved mature collagen integration by eight weeks with low inflammation.
