Abstract
A suture anchor includes a placement portion frangably connected to an attachment portion. The attachment portion includes an outwardly projecting barb. During insertion of the suture anchor within a bore hole formed on a bone, the barb scores at least a portion of the bone bounding the bore hole. Once the suture anchor is disposed within the bore hole, a withdrawal force is applied to the suture anchor such that the attachment portion thereof rotates within the bore hole and disconnects from the placement portion. In an alternative embodiment, the suture anchor can be formed without the outwardly projecting barb.
