Abstract

Fixation assemblies having a button captured by a continuous (i.e., closed) loop of thread, such as ultra high molecular weight polyethylene (UHMWPE) fiber are disclosed herein. Preferred assemblies are constructed such that the intact button cannot be detached from the continuous loop without breaking or opening the loop of fiber. The closed fiber advantageously contains at least one or two stitched, or otherwise secured or reinforced, sections positioned on the loop.

Claims (27)

1. A method of making a continuous loop fixation assembly comprising:

a) providing an open fiber having a first tail and a second tail and having a lumen;

b) inserting said first tail within said lumen of the fiber at a first position and pulling said first tail out of the lumen at a second position, and then retracting said first tail back into said lumen at said second position, to form a loop;

c) inserting said second tail within said lumen of said fiber at said second position and pulling the second tail out of the lumen at said first position, and then retracting said second tail back into said lumen at said first position, thereby creating a closed loop assembly with no free ends; and

d) reinforcing a first length of said loop that includes the first tail within the lumen, so that said first tail is retained in said lumen and a first reinforced section is created.

2. The method of claim 1 , further comprising:

a) providing an anchor button having an aperture; and

b) prior to inserting said first tail into said lumen, threading said open fiber through the aperture of said anchor button, so that said anchor button is engaged to said loop and forms a part of said closed loop assembly.

3. The method of claim 2 , wherein said anchor button has a first aperture and a second aperture, and wherein prior to inserting the first tail into said lumen, said open fiber is threaded through both said first aperture and said second aperture, so that said anchor button is engaged to said loop by said first and second aperture and forms a part of said closed loop assembly.

4. The method of claim 3 , wherein said anchor button has a third aperture and a fourth aperture, and wherein said open fiber is threaded through neither said third aperture or said fourth aperture, thereby leaving said third and fourth apertures available for securing additional sutures.

5. The method of claim 1 , wherein said first reinforced section of said loop includes said first and second positions, thereby retaining said first and second tails in position in said lumen.

6. The method of claim 5 , wherein said first and second tails overlap inside said lumen and further including reinforcing a second length of said loop that includes a portion of the overlap of said first tail and said second tail, thereby creating a second reinforced section and retaining said first tail and said second tail within said lumen.

7. The method of claim 6 , wherein said first and second reinforced sections of said loop are stitched.

8. The method of claim 1 , wherein said first tail and said second tail are inserted into said lumen with a lacing tool.

9. The method of claim 8 , further comprising:

a) inserting said lacing tool into said lumen at a first entry point in said fiber;

b) pushing said lacing tool out at a first exit point in said fiber;

c) coupling said first tail to said lacing tool;

d) pulling said lacing tool to insert said first tail into said lumen of said fiber;

e) inserting said lacing tool into said lumen at a second entry point in said fiber;

f) pushing said lacing tool out at a second exit point in said fiber;

g) coupling said second tail to said lacing tool; and

h) pulling said lacing tool to insert said second tail into said lumen of said fiber.

10. The method of claim 9 , wherein an end of said first tail coupled to said lacing tool is pulled out of said lumen through said first entry point and an end of said second tail coupled to said lacing tool is pulled out of said lumen through said second entry point, and further comprising retracting said first tail and second tail back into said lumen.

11. The method of claim 1 , wherein said first tail and second tail occupy an entire circumference of said loop's lumen, or substantially so.

12. The method of claim 1 , wherein said open fiber is ultra high molecular weight polyethylene.

13. The method of claim 1 , wherein said first tail is cut, prior to being retracted back into said lumen.
