Cannulated anchors are provided that may be optimally forced in, press fit, screwed in or otherwise installed into tissue with minimal damage to the flexible members or sutures attached thereto. Systems for installing at least one flexible member into tissue include the cannulated anchor, the at least one flexible member capable of being received by the cannulated anchor and an installer with a driver head insertable into the cannulation of the anchor proximate the trailing end and with an essentially longitudinal cannulation centrally disposed along the axis and sized to accept a guidewire therethrough. Movement of the installer about the longitudinal axis causes corresponding movement of the cannulated anchor such that the outer surface of the cannulated anchor is capable of effecting anchoring into the tissue.
