title: The role of transforming growth factor-beta and bone morphogenetic protein with fibrin glue in healing of bone-tendon junction injury.
abstract: Bone-tendon junction injuries have poor healing potential. This study evaluated the role of TGF-beta and BMP-2 in a fibrin glue carrier in healing of injuries at bone-tendon junction. Seventy-two skeletally mature male rabbits were divided into 4 groups. The tendo-Achilles was surgically transected at its insertion and reattached with a pullout suture. Group 1 served as a control. In groups 2, 3, and 4, fibrin glue, a mixture of TGF-beta and fibrin glue, and a mixture of BMP-2 and fibrin glue were injected into the bone-tendon junction. The animals were sacrificed at 2, 4 and 8 weeks after surgical procedure. The addition of TGF-beta to fibrin glue did not significantly improve the biomechanical properties of repair tissue. BMP-2 in combination with fibrin glue accelerates healing in a bone-tendon injury and also improves the histological and biomechanical properties of the repair tissue so formed.
