1. A method for securing a sleeve in a bore hole in bone, the bore hole having an opening, a base and a wall extending between the base and opening, the method comprising the steps of:

disposing at least a portion of a length of filament into the bore hole;

implanting the sleeve into the bore hole such that a first pathway extending through first and second ends of the sleeve opens in a direction toward the opening of the bore hole and in a direction toward the base of the bore hole;

pulling at least a portion of the length of filament through the first pathway of the sleeve, thereby forming a first loop configuration extending from the first end and at least one free end of the length of filament extending from the second end;

passing the at least one free end through the first loop configuration while the sleeve is in the bore hole to create a one-way cinch.

2. The method of claim 1 , wherein the length of filament is adapted to apply tension to a tissue in working relationship with the length of filament.

3. The method of claim 1 , wherein the sleeve is made of filamentary material.

4. The method of claim 1 , further comprising:

engaging the length of filament with an inserter device prior to the disposing step; and

disengaging the inserter device from the length of filament after the pulling step.

5. The method of claim 4 , wherein the inserter device includes a filament engagement element for engaging and retaining the length of filament, and wherein disengaging the inserter device from the first loop configuration includes moving the filament engagement element from a first position to a second position to release the length of filament.

6. The method of claim 1 , further comprising tensioning the at least one free end such that the first loop configuration, with the at least one free end positioned therethrough, travels toward and into the first pathway of the sleeve.

7. The method of claim 1 , wherein the sleeve further includes a sidewall and a plurality of fenestrations extending through the sidewall into the first pathway, and wherein when the sleeve is implanted in the bore hole, each of the plurality of fenestrations are disposed adjacent to and open towards the wall of the bore hole.

8. The method of claim 1 , wherein the implanting step includes orienting the sleeve in the bore hole so that the second end of the sleeve faces the base and the first end of the sleeve faces the opening and so that the free end of the length of filament extends from the second end of the sleeve toward the opening of the bore hole between the bone and an outer surface of the sleeve.

9. A method for securing a sleeve in a bore hole in bone, the bore hole having a base, an opening, and a wall disposed between the base and opening, the method comprising the steps of:

implanting the sleeve into the bore hole, the sleeve having a length defined between a first end and a second end and a first pathway extending along the length of the sleeve;

passing at least a portion of a length of filament through the first pathway from the second end through the first end such that the at least a portion of the length of filament forms a first loop configuration that extends from the first pathway at the first end and at least one free segment of the length of filament having a free end that extends from the second end; and

after the implanting step, passing the free end of the at least one free segment through the first loop configuration such that the first loop configuration, with the free end positioned therethrough, forms a one-way cinch.

10. The method of claim 9 , wherein the first loop configuration and the first end of the sleeve traps the at least one free segment to form the one-way cinch.

11. The method of claim 9 , prior to the passing steps, further comprising the step of engaging the at least a portion of the length of filament with an inserter device.

12. The method of claim 11 , further comprising disengaging the inserter device from the length of filament after the step of passing the at least a portion of the length of filament through the first pathway to form the first loop configuration.

13. The method of claim 12 , wherein disengaging the inserter device from the first loop configuration includes actuating a filament engagement element to release the length of filament.

14. The method of claim 9 , wherein the sleeve further includes an outer surface and a plurality of openings extending from the outer surface into the first pathway, and wherein when the sleeve is implanted in the bore hole, each of the plurality of openings are disposed adjacent to and open towards the wall of the bore hole.

15. The method of claim 9 , wherein the implanting step includes orienting the sleeve in the bore hole so that the second end of the sleeve faces the base and the first end of the sleeve faces the opening and so that the free end of the length of filament extends from the second end of the sleeve toward the opening of the bore hole between the bone and an outer surface of the sleeve.
