1. A fastener for securing a suture relative to a body tissue, comprising:

  • a first member comprised of an outer shell defining a circumferential longitudinal passage along a central longitudinal axis having a pair of slots through the outer shell of the first member and at least two key elements positioned about the interior surface of the circumferential longitudinal passage of the first member; and

    a second member configured for insertion along the central longitudinal axis into the circumferential longitudinal passage of the first member and rotatable about the central longitudinal axis in a first direction with respect to the first member, the second member comprising a first end, a second end, and a center portion, the center portion having a passage transverse to the central longitudinal axis, wherein at least one of the first and second ends of the second member have a cross sectional area larger than the cross sectional area of the center portion, and the second member having a plurality of engagement members radially positioned thereon,wherein the slots of the first member are configured to align with the passage transverse to the central longitudinal axis of the second member to enable passage of a suture through the first member and the second member,wherein rotation of the second member about the longitudinal axis in the first direction causes a portion of suture to wrap around a portion of the second member between the first and second members,wherein the key elements engage the engagement members to prevent rotation of the second member with respect to the first member in a second direction opposite to the first direction, andwherein the fastener is configured to secure soft tissue to bone.
