1. A suture anchor assembly comprising:
an anchor body including a longitudinal axis, an exterior surface, a proximal end, and a distal end, the anchor body including a first opening at the proximal end of the anchor body, the anchor body including an internal passage extending along the longitudinal axis from the first opening through at least a portion of a length of the anchor body, the anchor body including an external helical thread on the exterior surface, the external helical thread extending along the anchor body, the anchor body including a second opening through the exterior surface of the anchor body, wherein the second opening is distal of the first opening, the anchor body including a third opening through the exterior surface of the anchor body and distal of a rigid support of the anchor body, wherein the third opening is distal of the second opening, the rigid support having a leading distal surface, wherein the rigid support extends across the longitudinal axis of the anchor body, a wall is defined by the external helical thread on the exterior surface of the anchor body and a surface of the internal passage, and the rigid support is attached to the surface of the internal passage at an axially fixed longitudinal position, wherein the external helical thread extends 360 degrees around the longitudinal axis for at least a portion of the length of the anchor body; and a suture strand extending out of the first opening of the anchor body, wherein a portion of the suture strand is disposed in the internal passage between the rigid support and the first opening, the suture strand is supported by the leading distal surface of the rigid support, and the suture strand is disposed in the first opening, the second opening and the third opening of the anchor body. |
