1. A bone anchor for coupling soft tissue to bone comprising:
- a bone coupling portion including a plurality of bone locking features;
a tissue coupling portion adjacent to the bone coupling portion, the tissue coupling portion defining an aperture and a suture coupling feature; and
a suture construct seated within the aperture, the suture construct extending from a first end to a second end and including a first adjustable loop and a second adjustable loop, wherein the first end of the suture construct extends through a first passage portion defined by the suture construct and the second end of the suture construct extends through a second passage portion defined by the suture construct,wherein pulling the first end of the suture construct decreases a length of the first adjustable loop,wherein the first and second passage portions positioned at the aperture in the tissue coupling portion to substantially fix the passage portion at the aperture.

Abstract
A method and apparatus for coupling a soft tissue implant into a locking cavity formed within a bone. The method includes the following: implanting in bone a first anchor including a first suture construct connected to the first anchor; passing a first adjustable loop of the first suture construct at least one of over or through the soft tissue; coupling the first adjustable loop to one of a first locking feature of the first anchor or a second locking feature of a second anchor; adjusting the first adjustable loop by pulling a first end of the first suture construct; and securing the soft tissue against bone by pulling the first end of the first suture construct.

7. A bone anchor comprising:
-
a bone coupling portion including a bone locking feature; a suture coupling feature for coupling a first portion of a suture and defining an aperture; and a suture construct configured to be disposed within the aperture, wherein the suture construct includes a continuous braided body defining a longitudinally extending first passage portion and a longitudinally extending second passage portion, and a first suture portion extending from the continuous braided body and passing into the first passage portion and out of the first passage portion so as to place the first suture portion outside of the first passage portion, and define an adjustable first loop, and a second suture portion extending from the continuous braided body and passing into the second passage portion and out the second passage portion, so as to place the second suture portion outside of the second passage portion, and define an adjustable second loop, wherein the first passage portion and the second passage portion are positioned at the aperture in the suture coupling feature to couple the suture construct to the aperture. - View Dependent Claims (8, 9, 10, 11, 12)

13. An anchor for coupling soft tissue to bone comprising:
-
a bone coupling portion at a first end of the anchor; a suture coupling hook at a second end of the anchor; and a suture construct disposed within an aperture at the second end of the anchor, wherein the suture construct includes;
(i) a continuous braided body defining a longitudinally extending passage;
(ii) a first end extending from the continuous braided body and passing through a first aperture in the continuous braided body, through a first portion of the passage in a first direction, and out a second aperture in the continuous braided body so as to place the first end outside of the passage, and define a first loop; and
(iii) a second end extending from the continuous braided body and passing through a third aperture in the continuous braided body, through a second portion of the passage in a second direction, the second direction being opposite of the first direction, and out a fourth aperture in the continuous braided body so as to place the second end outside of the passage, and define a second loop,wherein the longitudinally extending passage is positioned within the aperture at the second end of the anchor to couple the suture construct to the anchor. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
