The disclosure provides examples of an open architecture anchor for securing soft tissue to bone, for example, to repair a torn rotor cuff. The anchor includes at least one open helical coil defining a polygonal internal volume and at least one rib disposed within the polygonal internal volume and connected to at least two turns of the at least one open helical coil. The at least one rib is sized to engage a driver and a combination of the at least one rib and the polygonal internal volume is sized to provide an anchor drive torque required to drive the anchor into bone.
