A bone anchor insertion device (10) comprises a handle (12), a nosepiece (14) connected to a distal end of the handle, a bone anchor connected to the nosepiece (14), and an actuator (22) disposed on the handle (12) for deploying the bone anchor, which suture is also fixed to a portion of soft tissue to be attached to a portion of bone. A suture ratchet (20) or tensioning mechanism is disposed in the handle (12) for tensioning suture which is associated with the bone anchor. This mechanism (20) permits precise tensioning, while also permitting one hand operation, thereby allowing the practitioner to use his or her other hand for other activities, such as camera operation or the like.
