SCAFFOLD APPARATUS FOR PROMOTING TENDON-TO-BONE FIXATION

摘要

This invention provides a graft collar for fixing tendon to bone. In one embodiment, the graft collar comprises a sheet of biopolymer mesh. In another embodiment, the graft collar comprises a polymer-fiber mesh. In another embodiment, the graft collar comprises (a) a first region comprising a biopolymer mesh and hydrogel and (b) a second region adjoining the first region and comprising a biopolymer mesh. In another embodiment, the graft collar comprises (a) a first region comprising a polymer-fiber mesh and hydrogel and (b) a second region adjoining the first region and comprising a polymer-fiber mesh.
