Method and apparatus for coupling soft tissue to a bone
A method and apparatus for coupling a soft tissue implant into a locking cavity formed within a bone is disclosed. The apparatus includes a member to pull the soft tissue implant into a femoral tunnel. The member includes a suture having first and second ends which are passed through first and second openings associated with the longitudinal passage to form a pair of loops. Portions of the suture lay parallel to each other within the suture. Application of tension onto the suture construction causes retraction of the soft tissue implant into the femoral tunnel.
1. A method for securing soft tissue to bone, comprising:
locating an elongate bone engaging member in a longitudinal bore formed in a bone with an adjustable suture construct extending down into the elongate bone engaging member through an opening in a trailing end of the elongate bone engaging member, around an interior portion of the elongate bone engaging member, and back out the elongate bone engaging member through the opening in the trailing end of the elongate bone engaging member to couple the adjustable suture construct to the elongate bone engaging member,
wherein the adjustable suture construct includes a suture with a first free end and a second free end,
wherein the suture further comprises a first aperture and a second aperture which are separate apertures in the suture and which occur successively along the suture such that, in a direction from the first free end to the second free end, the first aperture precedes the second aperture,
wherein the first free end extends into the suture through the second aperture, longitudinally within the suture along a longitudinal passage in the suture between the second aperture and the first aperture, and out of the suture through the first aperture to form a self-locking adjustable loop,
wherein the adjustable suture construct includes only a single self-locking adjustable loop which is said self-locking adjustable loop,
wherein the adjustable suture construct being coupled to the elongate bone engaging member includes the longitudinal passage in the suture extending longitudinally within the elongate bone engaging member and further includes the second aperture in the suture being positioned within the elongate bone engaging member,
wherein the adjustable suture construct includes a knot formed in the suture between the second aperture and the second free end of the suture, and
wherein at least a portion of the self-locking adjustable loop protrudes from the opening in the trailing end of the elongate bone engaging member and extends around a portion of soft tissue positioned over the bone; and
pulling on the first free end of the suture from outside the bone so as to decrease a size of the self-locking adjustable loop for pulling the portion of soft tissue toward the bone.
2. The method of claim 1 further comprising coupling the adjustable suture construct to a second elongate bone engaging member that is located in a second longitudinal bore in the bone spaced from the first longitudinal bore.
3. The method of claim 1 , wherein the elongate bone engaging member comprises a threaded member.
4. The method of claim 1 , wherein the suture comprises a braided body.
5. The method of claim 4 , wherein the first aperture and the second aperture are formed during the braiding process as loose portions between pairs of fibers.
6. The method of claim 1 , wherein the first aperture in the suture is also positioned within the elongate bone engaging member.
7. The method of claim 1 , wherein the soft tissue is a rotator cuff.
8. A method for securing soft tissue to bone, comprising:
locating an elongate bone engaging member in a longitudinal bore formed in a bone with a suture extending down into the elongate bone engaging member through an opening in a trailing end of the elongate bone engaging member to couple the suture to the elongate bone engaging member, the suture including a first free end and a second free end;
passing the first free end of the suture up through a soft tissue positioned over the bone; and
pulling on the first free end of the suture from outside the bone as the suture is extending through the soft tissue, wherein the first free end has been made to extend through a longitudinal passage in the suture to form a self-locking adjustable loop that includes at least a portion of the self-locking adjustable loop protruding from the opening in the trailing end of the elongate bone engaging member and extending around a portion of the soft tissue,
wherein the suture comprises a first aperture and a second aperture which are separate apertures in the suture and which occur successively along the suture such that, in a direction from the first free end to the second free end, the first aperture precedes the second aperture,
wherein the first free end extends into the suture through the second aperture, longitudinally within the suture along the longitudinal passage, and out of the suture through the first aperture to form the self-locking adjustable loop,
wherein the adjustable suture construct has been made to include only a single self-locking adjustable loop which is said self-locking adjustable loop,
wherein the adjustable suture construct has been made to include a knot formed in the suture between the second aperture and the second free end of the suture, and
wherein said pulling decreases a size of the self-locking adjustable loop for pulling the portion of the soft tissue toward the bone.
9. The method of claim 8 further comprising coupling the adjustable suture construct to a second elongate bone engaging member that is located in a second longitudinal bore in the bone spaced from the first longitudinal bore.
10. The method of claim 8 , wherein the elongate bone engaging member comprises a threaded member.
11. The method of claim 8 , wherein the suture comprises a braided body.
12. The method of claim 11 , wherein the first aperture and the second aperture are formed during the braiding process as loose portions between pairs of fibers.
13. The method of claim 8 , wherein the longitudinal passage in the suture extends longitudinally within the elongate bone engaging member.
14. The method of claim 13 , wherein the second aperture in the suture is positioned within the elongate bone engaging member.
15. A method for securing soft tissue to bone, comprising:
passing suture of an adjustable suture construct through soft tissue positioned over a bone, wherein during said passing the suture is anchored inside the bone to an elongate bone engaging member located in a longitudinal bore formed in the bone, the anchored suture extending down into the elongate bone engaging member through an opening in a trailing end of the elongate bone engaging member, around an interior portion of the elongate bone engaging member, and back out of the elongate bone engaging member through the opening in the trailing end of the elongate bone engaging member, the adjustable suture construct including a suture with a first free end that extends longitudinally through a longitudinal passage in the suture to form a self-locking adjustable loop, wherein at least part of the self-locking adjustable loop extends around a portion of the soft tissue following said passing; and
pulling on the first free end of the suture from outside the bone so as to decrease a size of the self-locking adjustable loop for pulling the portion of the soft tissue toward the bone,
wherein the suture further comprises a first aperture and a second aperture which are separate apertures in the suture and which occur successively along the suture such that, in a direction from the first free end to a second free end of the suture, the first aperture precedes the second aperture,
wherein the first free end extends into the suture through the second aperture, longitudinally along the longitudinal passage in the suture between the second aperture and the first aperture, and out of the suture through the first aperture to form the self-locking adjustable loop,
wherein the adjustable suture construct includes only a single self-locking adjustable loop which is said self-locking adjustable loop,
