Lecithin-based multifunctional composite hydrogel membrane: Synergistic prevention of postoperative tendon adhesion via hydration lubrication and immunomodulation.
Postoperative tendon adhesion is mainly driven by mechanical irritation and oxidative stress-induced inflammation at the injury site, which activates fibroblasts and disrupts the local immune microenvironment, thereby impairing tendon gliding and functional recovery. Thus, a biomaterial integrating lubrication, anti-ad...
