1. A method of augmenting reattachment of a tendon to a bone using an implant having a peg portion and a sheet portion, the method comprising:
creating a cavity in the bone;
placing the peg portion of the implant into the cavity in the bone; and
using sutures to re-approximate and tie down the tendon to effect the reattachment of the tendon to bone,
wherein the implant comprises:
a plurality of fibers made from demineralized bone fibers (DBF), collagen fibers, biocompatible polymer fibers, and/or resorbable polymer fibers, the plurality of fibers forming a contiguous shape comprising the peg portion and the sheet portion;
wherein the peg portion has a cone or truncated cone shape with a distal open or closed end and a proximal open end;
wherein the peg portion is capable of being inserted by the distal open or closed end first into a cavity of a bone;
wherein the sheet portion is attached to and surrounds the proximal open end of the peg portion;
wherein the sheet portion has a first side and a second side, and
wherein, during use: the first side is in contact with an area on the surface of the bone adjacent the cavity, and the second side contacts the tendon, the sheet portion thereby forming an interface between the tendon and the bone.
