The provided system includes an inserter, a bone anchor, and one or more sutures. The inserter includes a tube and a plunger within the tube's interior. The bone anchor is structured with multiple deformable members such that it can be transitioned from a compact configuration to an expanded configuration. When inserting the bone anchor, the bone anchor may initially be in a compact configuration within the inserter tube. The inserter tube may be inserted into a bone hole. Then, while the plunger is maintained in its positioned, the tube may be retracted so that the bone anchor is deployed from within the tube. The bone anchor may then be transitioned to an expanded configuration. In some instances, suture tension transitions the bone anchor. In other instances, a pre-set shape of a shape memory material transitions the bone anchor.
