A suture anchor includes two clamping surfaces that secure one or more suture strands between them. Cooperating engaging structures, such as recesses and a projection enable the clamping surfaces to be incrementally moved closer together such that the force applied between the clamping surfaces is increased in predetermined increments to secure the suture strands. If the applied force is too high, the clamping surfaces can be released from a fixed position, and the force applied by the clamping surfaces can again be incrementally increased to the desired clamping force. A guide is provided to mark the location of the hole that has been drilled in the bone. A suture anchor delivery tool is provided to insert and secure the suture anchor in the hole in the bone. The suture anchor delivery tool enables the surgeon to move the clamping surfaces of the suture anchor towards each other.
