Abstract

Methods of attaching a soft tissue to an adjacent bone at a defect site are provided. At least one adjustable loop of a flexible construct is passed through the soft tissue. The at least one adjustable loop is passed through a passage construct. A locking member is passed through the at least one adjustable loop and the adjustable loop is reduced about or within the locking member such that the at least one loop is frictionally retained in the passage construct and locked in place by the locking member to thereby secure the soft tissue.

6. The method according to claim 1, wherein passing the locking member through the first and second adjustable loops includes passing the locking member through the first and second adjustable loops adjacent a surface of the second tissue facing a direction opposite the first tissue.

7. The method according to claim 1, wherein passing the locking member through the first and second adjustable loops includes passing an elbow slidably coupled to a flexible member loop through the first and second adjustable loops.

8. The method according to claim 1, wherein passing the locking member through the first and second adjustable loops further comprises forming a locking member assembly including:

forming a pathway construct as a coil using at least a second flexible member so as to position third and fourth adjustable loops relative to the coil; and

passing a portion of the locking member assembly through the first and second adjustable loops.

9. The method according to claim 8, wherein passing the portion of the locking member assembly through the first and second adjustable loops includes passing the third adjustable loop through the first and second adjustable loops.

10. The method according to claim 9, wherein passing the third adjustable loop through the first and second adjustable loops includes passing an elbow slidably coupled to the third adjustable loop through the first and second adjustable loops.

11. The method according to claim 10, further comprising:

positioning the fourth adjustable loop around respective portions of the first and second adjustable loops extending through the second tissue; and

reducing a size of the fourth adjustable loop so as to constrict the fourth adjustable loop around the respective portions of the first and second adjustable loops.

12. The method according to claim 11, wherein reducing the size of the fourth adjustable loop includes reducing the size of the fourth adjustable loop after passing the third adjustable loop though the first and second adjustable loops.

13. The method according to claim 11, wherein reducing a size of the first and second adjustable loops about the locking member includes reducing a size of the first and second adjustable loops about the elbow to retain the first and second adjustable loops relative to the second tissue and draw the elbow and second tissue toward the first tissue.

14. The method according to claim 1, wherein positioning the fastener in the first tissue includes positioning the fastener in bone.

15. A method of attaching a first tissue to a second tissue at a site, comprising:

attaching an adjustable flexible member construct to a fastener, the flexible member construct including a flexible member having a body defining a passage portion and first and second ends, the first and second ends extending through the passage portion to form first and second adjustable loops relative to the passage portion;

positioning the fastener in the first tissue;

attaching the first and second adjustable loops to the second tissue;

passing a portion of a locking member assembly through the first and second adjustable loops; and

reducing a size of the first and second adjustable loops about the portion of the locking member assembly such that the first and second adjustable loops are retained relative to the second tissue and the second tissue is fixed to the first tissue.

16. The method according to claim 15, further comprising forming the locking member assembly including:

forming a pathway construct as a coil using at least a second flexible member so as to position third and fourth adjustable loops relative to the coil; and
