Evaluation of High-Purity Type I Collagen Biologic Wrap to Improve Function After Extensor Tendon Repair of the Hand

Brief Summary

Tendon injuries of the hand, particularly extensor tendons, are prone to postoperative adhesions, extensor lag, and stiffness, leading to functional impairment. This multicentric randomized controlled trial evaluates whether wrapping repaired extensor tendons with a high-purity Type I collagen (HPTC) biologic membrane can reduce adhesion formation and improve functional outcomes compared with standard repair alone.
