Narrative review highlights macrophage polarization through biomaterials in tendon-bone repair, suggesting targeted immune modulation improves tissue regeneration.

Key Points

To review the distinct roles of macrophage phenotypes in tendon-bone healing and evaluate immunomodulatory biomaterials designed to guide macrophage responses for improved tissue repair.
Synthesized literature examining the physiological and mechanical challenges of repairing the tendon-to-bone interface.
Assessed the temporal shifts between pro-inflammatory M1 and pro-regenerative M2 macrophage phenotypes during healing.
Evaluated emerging biomaterial strategies engineered to modulate macrophage phenotypes and identified current translational challenges.
Injuries to the tendon-to-bone interface typically heal with biomechanically inferior fibrous scar tissue rather than regenerating the native structure.
Tendon-bone healing requires a coordinated transition from early-stage M1 macrophages to late-stage M2 macrophages to successfully promote structural integration.
Immunomodulatory biomaterials capable of guiding macrophage phenotypic switching improve healing outcomes, though significant challenges remain for clinical application.
