A knotless anchor (100) includes an elongate body (102), a plurality of wings (104) extending outward from the body, a plurality of grooves (106) corresponding to the wings formed in the body, and a transverse bore (110) in communication with the grooves. The wings may be pivotably attached to the body, allowing movement between an open position, where the wings do not engage the grooves, and a closed position, where at least a portion of each wing engages its corresponding groove. A suture (122) routed through the grooves and the transverse bore is frictionally secured to the suture when the wings are urged in the closed position. In use, the wings may be urged into the closed position when inserted into a recess smaller than the cross-section of the anchor, such as a hole formed in a bone.
