[0024] This disclosure relates to systems and methods for performing tensionable knotless tissue repairs. Locking collars, including a one-way locking mechanism, can be used as part of a tensionable knotless tissue repair for tensioning and locking one or more strands of suture. These and other features of this disclosure are described in more detail below.

[0025] An exemplary locking collar for performing tissue repair may in particular include a body extending between a first end and a second end and including an outer diameter wall, an inner diameter wall, and a cannula surrounded by the inner diameter wall. An eyelet is connected to the body. A plurality of locking barbs extend into the cannula and are configured to lock sutures received through the eyelet and the cannula relative to the body.

[0026] In any other embodiment, the eyelet is integrally formed with the body.

[0027] In any other embodiment, the body is made of a first material, and the aperture is made of a second material different from the first material.

[0028] In any other embodiment, the second material includes sutures.

[0029] In any other embodiment, the eyelet is connected to the second end.

[0030] In any other embodiment, the eyelet includes a band attached to the second end and a suture channel extending between the band and the second end.

[0031] In any other embodiment, the suture is looped around the band.

[0032] In any other embodiment, the plurality of locking barbs are angled in the direction toward the eyelet.

[0033] In any other embodiment, the plurality of locking barbs are angled in a direction away from the eyelet.

[0034] In any other embodiment, the eyelet is connected to the first end.

[0035] In any other embodiment, a cap is provided at the second end.

[0036] In any other embodiment, the cap includes a diameter that is increased compared to the diameter of the outer diameter wall of the body.

[0037] In any other embodiment, each of the plurality of locking barbs protrudes inward from the inner diameter wall.

[0038] In any other embodiment, a plurality of locking barbs are arranged in at least a first row and a second row.

[0039] In any other embodiment, the first portions of the plurality of locking barbs in the first row are staggered relative to the second portions of the plurality of locking barbs in the second row.

[0040] Exemplary surgical methods may include loading a suture through an eyelet of a locking collar, passing the suture through a cannula of the locking collar, tensioning the suture in a first direction, and locking the suture within the cannula to prevent movement of the suture in a second direction.

[0041] In any other embodiment, the surgical method includes passing the suture through or around the tissue before passing the suture through the locking collar of the cannula.

[0042] In any other embodiment, the body of the locking collar includes a first end and a second end, and an eyelet is connected to the first end. Passing the suture through the cannula includes inserting it at the first end and passing the suture through the cannula in a direction toward the second end of the body.

[0043] In any other embodiment, the body of the locking collar includes a first end and a second end, and an eyelet is connected to the second end. Passing the suture through the cannula includes inserting it at the first end and passing the suture through the cannula in a direction toward the second end of the body.

[0044] Another exemplary locking collar for performing tissue repair may include a body comprising an outer diameter wall, an inner diameter wall, and a cannula surrounded by the inner diameter wall. A plurality of locking barbs extend into the cannula and are configured to lock sutures received through the cannula relative to the body. A transverse through-hole extends through the body between a first and second row of the plurality of locking barbs.

[0045] Figures 1 to 4 An exemplary locking collar 10 is shown that can be used in performing various tensionable knotless tissue repairs. For example, the locking collar 10 can be used during surgical procedures to attach tissue (e.g., ligaments, tendons, grafts, etc.) to bone, to repair fractures as part of a cerclage technique, to perform tissue reconstruction surgery (e.g., ACL / PCL reconstruction), or to repair any other type of tissue effect.

[0046] The locking collar 10 may include a body 12 extending along a longitudinal axis A between a first end 14 and a second end 16. The body 12 may be tubular and may be made of metallic or plastic material. However, the specific size, shape, and material composition of the body 12 are not intended to limit this disclosure.

[0047] The cannula 18 can extend through the body 12 and can be configured to accommodate one or more strands of suture (see example). Figure 4The internal channel of the suture 20 shown. The cannula 18 can extend along the entire length of the body 12, and thus from the first end 14 to the second end 16. The longitudinal axis A can bisect the cannula 18.

[0048] The body 12 may include an outer diameter wall 22 and an inner diameter wall 24. The outer diameter wall 22 may be smooth, or may alternatively include threads, barbs, or other features for facilitating bone fixation. The inner diameter wall 24 may surround the cannula 18. In some embodiments, the cannula 18 may taper toward the first end 14 or the second end 16.

[0049] Multiple locking barbs 26 may protrude inward from the inner diameter wall 24. Therefore, the locking barbs 26 may occupy at least a portion of the open space of the cannula 18. In one embodiment, the locking barbs 26 are integrally formed (e.g., molded) features of the body 12 of the locking collar 10. The locking barbs 26 may be provided along the entire length of the cannula 18 or only at selected portions thereof. The locking barbs 26 may be a rigid or flexible structure.

[0050] The locking barbs 26 can be arranged in multiple rows along the length of the cannula 18. For example, the locking barbs 26 can be arranged in at least a first row R1 and a second row R2 (see...). Figure 3 In one embodiment, the locking barbs 26 of the second row R2 are staggered relative to the locking barbs 26 of the first row R1 (see [link]). Figure 3 ).

[0051] Each locking barb 26 may include a sharp or pointed tip 28, and in this embodiment, each locking barb 26 may be angled in a direction toward the second end 16. Thus, the locking barbs 26 can establish a one-way locking mechanism that allows one or more sutures 20 to pass through the cannula in a first direction D1 while preventing the sutures 20 from being tensioned or otherwise moved in a second direction D2. Once the sutures 20 have passed through the cannula 18, the staggered arrangement of the rows of locking barbs 26 can provide maximum engagement with the suture.

[0052] The locking collar 10 may additionally include an eyelet 30. The eyelet 30 may include a band 32 attached to or integrally formed with the body 12 of the locking collar 10. The band 32 may be made of the same material as the body 12 or a different material (e.g., thread). In one embodiment, the band 32 is attached to the body 12 at or near its second end 16. Thus, in this embodiment, the locking barb 26 is angled in a direction toward the band 32. The open space extending between the band 32 and the second end 16 of the body 12 can establish a stitch channel 34 for the eyelet 30.

[0053] Currently, the main reference is... Figure 4 Continue to refer to Figures 1 to 3One or more sutures 20 can be loaded through eyelets 30 and then passed through cannula 18. Sutures 20 can be FiberWire®, FiberTape®, or any other suitable suture product. FiberWire® and FiberTape® are suture products sold by Arthrex, Inc. However, other suture products can be used for sutures 20 within the scope of this disclosure. The size and type of suture used in conjunction with the locking loop 10 are not intended to limit this disclosure. Sutures 20 can include a constant thickness or a varying thickness.

[0054] One or more sutures 20 can be accommodated within the suture channel 34, such that the sutures 20 form loops around the band 32. The sutures 20 can then be inserted into and pass through the cannula 18 at the first end 14 of the body 12. Once the sutures 20 have passed through the cannula 18, the free end 36 of the sutures 20 can be further tensioned in the first direction D1 to tension and lock the sutures 20 relative to the locking collar 10 in place. Locking barbs 26 prevent the sutures 20 from regressing or otherwise moving in the second direction D2. The tips 28 of the locking barbs 26 can cross each other with the sutures 20 to lock the sutures 20 and prevent their movement in the second direction D2.

[0055] Although shown in the above embodiment as locking a single folded suture 20, the locking loop 10 can be configured to receive and lock multiple strands of suture and / or sutures of different sizes.

[0056] As part of a variety of surgical procedures, the above-described and Figures 1 to 4 The locking collar 10 shown can be used to tension and secure one or more sutures 20 knotlessly. Figure 5 This schematically illustrates one such surgical method for repairing a fractured bone 38 as part of a cerclage technique. For example, a suture 20 can be received through the eyelet 30 of a locking loop 10 and then wrapped around the fractured bone 38. The suture 20 can then be inserted into a first end 14, passed through a cannula 18 in a direction toward a second end 16, and then tensioned to lock the suture 20 in place, thereby forming a cerclage to allow the fractured bone 38 to heal properly.

[0057] Figure 6Another exemplary surgical method that can benefit from the use of the locking collar 10 is illustrated schematically. For example, the locking collar 10 can be used to attach tissue 40 to bone 42, such as when tissue 40 is torn from bone 42. For example, suture 20 can be received through eyelet 30 and then passed through or around tissue 40 before the locking collar 10 is inserted into the opening 44 formed in bone 42. Suture 20 can then be passed through cannula 18 in a direction extending from first end 14 toward second end 16 and then tensioned to lock suture 20 in place, thereby bringing tissue 40 close to bone 42.

[0058] Figure 7 Another exemplary locking collar 110 is shown that can be used in performing various tensionable knotless tissue repairs. The locking collar 110 is similar to that discussed above and... Figures 1 to 6 The locking collar 10 is shown. However, in this embodiment, the eyelet 30 is located at or near the first end 14 of the body 12, rather than at or near the second end 16. Therefore, the locking barb 26 of the insertion tube 18 can be angled in a direction away from the eyelet 30 and the band 32.

[0059] In one embodiment, the cap 46 is disposed at or near the second end 16 of the body 12 of the locking collar 10. Thus, the cap 46 can be located on the end of the body 12 opposite the eyelet 30. The cap 46 may include a diameter increased compared to the outer diameter wall 22 of the body 12, and is therefore configured to be cortically positioned relative to the bone to provide cortical bone fixation. However, in some specific embodiments, the cap 46 may be omitted from the locking collar 110 (see, for example...). Figure 8 ).

[0060] Currently, the main reference is... Figure 9 Continue to refer to Figure 7 One or more sutures 20 can be loaded through eyelets 30 and then passed through cannula 18. The sutures 20 can first pass through suture channels 34, forming a loop around band 32. Then, the sutures 20 can be inserted into cannula 18 through the first end 14 of body 12 and extend through the length of cannula 18 in the direction toward the second end 16. Once the sutures 20 have fully passed through cannula 18, the free end 36 of the sutures 20 can be further tensioned in the first direction D1 to tension and lock the sutures 20 in place relative to locking collar 110. Locking barbs 26 prevent the sutures 20 from regressing or otherwise moving in the second direction D2. The tips 28 of the locking barbs 26 can cross each other with the sutures 20 to lock the sutures 20 and prevent their movement in the second direction D2.

[0061] In this embodiment, at least in part due to the positioning of the eyelet 30 at the first end 14, the suture 20 can form a suture loop 48 as it loops around the band 32 already around the eyelet 30 and passes through the cannula 18 in a direction extending from the first end 14 toward the second end 16. As part of the ligament reconstruction surgery, the graft 50 can be looped on the suture loop 48 and then secured by a locking collar 110 (see...). Figure 10 The locking collar 110 is suspended within the bone tunnel 52 of the bone 54. The locking collar 110 can be positioned relative to the bone 54 such that the body 12 of the locking collar 110 is accommodated within the bone tunnel 52, and the cap 46 is positioned relative to the cortex of the bone 54.

[0062] Figure 11 and Figure 12 Another exemplary locking collar 210 is shown that can be used in performing various tensionable knotless tissue repairs. In this embodiment, the locking collar 210 includes a transverse through-hole 60 instead of the eyelet 30 described above for connecting the suture 20. The transverse through-hole 60 may be formed through the body 12 and may extend along an axis B that is transverse to (e.g., perpendicular to) the longitudinal axis A of the body 12. The transverse through-hole 60 may traverse the cannula 18 and may extend at a location between locking barbs 26 in adjacent rows. Thus, the suture 20 can pass through the transverse through-hole 60 without engaging any locking barbs 26. The transverse through-hole 60 may be positioned closer to the first end 14 or the second end 16 than to the opposite end. In the illustrated embodiment, the transverse through-hole 60 is positioned closer to the second end 16 than to the first end 14. However, other configurations are possible within the scope of this disclosure.

[0063] The suture 20 can be loaded through the transverse through-hole 60 and then passed through the cannula 18 from either end, depending on the type of surgery being performed. Once the suture 20 has been passed through the cannula 18, the free end 36 of the suture 20 can be tensioned in the first direction D1 to tension and lock the suture 20 in place relative to the locking collar 210. The locking barb 26 prevents the suture 20 from regressing or otherwise moving in the second direction D2.

[0064] Figure 13 An exemplary suture 20 is shown that can be used in any of the specific embodiments described above. The suture 20 may include varying thicknesses. Thus, the suture 20 may include one or more tapered regions 70, wherein the suture 20 transitions between a thickened section 72 and a thinning section 74. The thinning section 74 may facilitate the passage of the suture 20 through the cannula 18 and / or through-hole 60, such as via a suitable suture loader, which may be provided as part of a suture locking system including, for example, a locking collar 10, and the thickened section 72 may provide a larger surface area for engagement of the locking barbs 26 to fully lock the suture 20 relative to the locking collar 10.

[0065] In one embodiment, the thickness of the thickened section 72 of the suture 20 is approximately twice that of the thinned section 74. However, other ratios (e.g., 1.5:1, 3:1, etc.) between the relative thicknesses (e.g., outer diameters) of the thickened section 72 and the thinned section 74 are contemplated within the scope of this disclosure.

[0066] The locking collar of this disclosure can be used to perform a variety of tensionable knotless tissue repairs. The locking collar provides tension and retension of the sutures at various points in the tissue repair (including after the implantation of the attached fixation device), thus offering many advantages over existing tissue repair techniques.

[0067] Although different non-limiting embodiments are shown to have specific components or steps, the embodiments disclosed herein are not limited to those specific combinations. It is possible to use some components or features from any non-limiting embodiment in combination with features or components from any other non-limiting embodiment.

[0068] It should be understood that the same reference numerals identify corresponding or similar elements throughout the various figures. It should also be understood that while particular component arrangements are disclosed and shown in these exemplary embodiments, other arrangements may also benefit from the teachings of this disclosure.

[0069] The foregoing description should be interpreted illustratively and not in any restrictive sense.
