This disclosure relates to the field of surgery, and more particularly to various surgical locking devices that are capable of locking suture when performing a variety of tensionable knotless surgical procedures.
Repetitive trauma to a joint, such as a knee, ankle, hip, elbow, or shoulder joint, for example, may result in the development of tissue defects (e.g., soft tissue tears, cartilage defects, etc.). If not treated, tissue defects could further deteriorate, thereby causing joint instability and discomfort.
This disclosure relates to systems and methods for performing tensionable knotless surgical procedures, such as tissue repairs or reconstructions, for example. Surgical locking devices that include a one-way locking mechanism may be utilized when performing the tensionable knotless surgical procedures for tensioning and locking one or more strands of suture.
An exemplary suture locking device may include, inter alia, a surgical button including a first opening and a second opening, and a plurality of locking barbs that establish a one-way locking mechanism for locking a suture relative to the surgical button.
Another exemplary suture locking device may include, inter alia, a bone plate including an opening, and a plurality of locking barbs that establish a one-way locking mechanism for locking a suture relative to the bone plate.
The embodiments, examples, and alternatives of the preceding paragraphs, the claims, or the following description and drawings, including any of their various aspects or respective individual features, may be taken independently or in any combination. Features described in connection with one embodiment are applicable to all embodiments, unless such features are incompatible.
The various features and advantages of this disclosure will become apparent to those skilled in the art from the following detailed description. The drawings that accompany the detailed description can be briefly described as follows.
This disclosure relates to systems and methods for performing tensionable knotless surgical procedures.

The locking ferrule 10 is an exemplary suture locking device that can include a cap portion 12 and a barrel portion 14 that protrudes from the cap portion 12. The cap portion 12 and the barrel portion 14 may be formed together as part of a unitary structure of the locking ferrule 10. In an embodiment, the cap portion 12 and the barrel portion 14 are arranged to provide a top hat-like appearance of the locking ferrule 10. However, the specific size, shape, and material make-up of the locking ferrule 10 are not intended to limit this disclosure.
The cap portion 12 of the locking ferrule 10 may include a top surface 16, a bottom surface 18, and a side wall 20 that extends between the top surface 16 and the bottom surface 18. The bottom surface 18 may include a slightly concave curvature for conforming to the contour of a bone. The barrel portion 14 may protrude outwardly from the bottom surface 18 of the cap portion 12. As further detailed below, the locking ferrule 10 may be positioned relative to a bone such that the barrel portion 14 is accommodated within a socket or tunnel formed in the bone and the cap portion 12 is seated relative to the cortex of the bone. In the seated position, the top surface 16 of the cap portion 12 faces away from the bone and the bottom surface 18 faces toward the bone.
A cannulation 22 may extend through the cap portion 12 and the barrel portion 14. The cannulation 22 may establish an internal passageway for accommodating one or more strands of suture 24 (see
The cannulation 22 may be circumscribed by an interior wall 26 of the locking ferrule 10. The interior wall 26 may be established by both the cap portion 12 and the barrel portion 14. The cannulation 22 may be straight or may taper in a direction toward a distal tip of the barrel portion 14. An outer diameter wall 28 of the barrel portion 14 may be smooth or could alternatively include threads, barbs, or other features for facilitating bone fixation.
A plurality of locking barbs 30 may protrude inwardly from the interior wall 26. The locking barbs 30 may therefore occupy at least a portion of the open space of the cannulation 22. In an embodiment, the locking barbs 30 are integrally formed (e.g., molded) features of the body of the locking ferrule 10. The locking barbs 30 may be provided along an entire length of the cannulation 22 or at only select portions thereof. The locking barbs 30 may be either rigid or flexible structures.
The locking barbs 30 may be arranged in multiple rows along the length of the cannulation 22. For example, the locking barbs 30 may be arranged in a least a first row R1 and a second row R2 (see
Each locking barb 30 may include a sharp or pointed tip 32, and, in this implementation, each locking barb 30 may be angled in a direction toward the cap portion 12. The locking barbs 30 may therefore establish a one-way locking mechanism that permits one or more sutures 24 to pass through the cannulation 22 in a first direction D1 while preventing the suture(s) 24 from being tensioned or otherwise moved in a second direction D2. The staggered relationship of the rows of locking barbs 30 can maximize engagement with the suture 24 once it is passed through the cannulation 22.
The suture 24 may be FiberWire®, FiberTape®, or any other suitable suture product. FiberWire® and FiberTape® are suture products marketed and sold by Arthrex, Inc. However, other suture products could be utilized for the suture 24 within the scope of this disclosure. The size and type of suture utilized in conjunction with the locking ferrule 10 are not intended to limit this disclosure.
The suture 24 may include a varying thickness. The suture 24 may therefore include one or more tapered regions 25 where the suture 24 transitions between a thickened section 27 and a thinned section 29 (see, e.g.,
In an embodiment, the thickened sections 27 of the suture 24 are about twice as thick as the thinned sections 29. However, other ratios (e.g., 1.5:1, 3:1, etc.) between the relative thicknesses (e.g., outer diameters) of the thickened sections 27 and the thinned sections 29 are contemplated within the scope of this disclosure.
The surgical method may include preparing a socket 38 in the bone 36. The socket 38 may be sized for receiving a portion of the graft 34. One or more sutures 24 may be attached to the graft 34 and can be used to pull or otherwise position the graft 34 within the socket 38. The suture 24 may be passed through the cannulation 22 of the locking ferrule 10 either before or after inserting the barrel portion 14 of the locking ferrule into a passage 40 of the bone 36 that is connected to the socket 38.
At this point of the surgical method, the graft 34 may be reduced into place within the socket 38. The suture 24 may subsequently be tensioned and locked in place by the locking ferrule 10. For example, after loading the suture 24 through the cannulation 22 of the locking ferrule 10, the suture 24 may be tensioned in the direction D1 to allow the pointed tips 32 of the locking barbs 30 to interdigitate with the section of the suture 24 accommodated within the cannulation 22, thereby locking the suture 24 in place and preventing it from sliding back in the second direction D2. The graft 34 can therefore be securely tensioned and fixated within the socket 38 of the bone 36.
In the above surgical method, a single locking ferrule 10 is used to tension and lock the suture 24. However, other surgical methods, such as a docking technique for performing an UCL repair, for example, may involve the use of multiple locking ferrules 10 for securing a graft 42 relative to a bone 44 (see
The suture 24 may be secured relative to the first bone 46 by a button 50. The suture 24 may subsequently be tensioned and locked in place relative to the second bone 48 using the locking ferrule 10. For example, after loading the suture 24 through the cannulation 22 of the locking ferrule 10, the suture 24 may be tensioned in the direction D1 to allow the pointed tips 32 of the locking barbs 30 to interdigitate with the section of the suture 24 accommodated within the cannulation 22, thereby locking the suture 24 in place and preventing it from sliding back toward the second direction D2. The suture 24 may be passed through the cannulation 22 of the locking ferrule 10 either before or after inserting the barrel portion 14 of the locking ferrule 10 into a passage 52 formed in the second bone 48. The suture 24 may tensioned until the second bone 48 is located at a desired position relative to the first bone 46.
The cap portion 112 of the locking ferrule 110 may include a top surface 116, a bottom surface 118, and a side wall 120 that extends between the top surface 116 and the bottom surface 118. The bottom surface 118 may include a slightly concave curvature for conforming to the contour of a bone. The barrel portion 114 may protrude outwardly from the bottom surface 118 of the cap portion 112. An outer diameter wall 128 of the barrel portion 114 may be smooth or could alternatively include threads, barbs, or other features for facilitating bone fixation.
A first cannulation 122A and a second cannulation 122B may extend through the cap portion 112 and the barrel portion 114. The first and second cannulations 122A, 122B may establish internal passageways for accommodating one or more strands of suture 124 (see, e.g.,
A dividing wall 154 may separate the first cannulation 122A and the second cannulation 122B from one another. The dividing wall 154 may be established by both the cap portion 112 and the barrel portion 114 of the locking ferrule 110.
The first cannulation 122A may include a plurality of locking barbs 130. The locking barbs 130 may protrude inwardly from an interior wall 126A that circumscribes the first cannulation 122A. The locking barbs 130 may therefore occupy at least a portion of the open space of the first cannulation 122A. In an embodiment, the locking barbs 130 are integrally formed (e.g., molded) features of the body of the locking ferrule 110. The locking barbs 130 may be provided along an entire length of the cannulation 122A or at only select portions thereof. Each locking barb 130 may include a sharp or pointed tip 132, and, in an exemplary implementation, each locking barb 130 may be angled in a direction toward the cap portion 112. The locking barbs 130 may establish a one-way locking mechanism that permits one or more sutures 124 (see
The second cannulation 122B may be circumscribed by an interior wall 126B. The second cannulation 122B may exclude locking barbs, and therefore the interior wall 126B can provide a substantially smooth surface that allows one or more sutures 124 to be shuttled through the locking ferrule 110 prior to being locked in place via the locking barbs 130 of the first cannulation 122A.
As shown in
Alternatively, as shown in
A post 169 may protrude from a distal end of the barrel portion 114 at a location between the first cannulation 122A and the second cannulation 122B. The post 169 may be curved to provide a smooth surface for suture 124 to glide over as it is being shuttled through the locking ferrule 110.
The locking ferrule 110 described above and shown in
The surgical method may include preparing a socket 138 in the bone 136. The locking ferrule 110 may be inserted into the bottom of the socket 138 either before or after connecting the suture 124 that is attached to the graft 134 to the locking ferrule 110.
At this point of the surgical method, the graft 134 may be reduced into place relative to the socket 138. The suture 124 may subsequently be tensioned and locked in place using the locking ferrule 110. For example, after loading the suture 124 through the first and second cannulations 122A, 122B of the locking ferrule 110, the suture 124 may be tensioned in the direction D1 to allow the pointed tips 132 of the locking barbs 130 to interdigitate with the section of the suture 124 accommodated within the first cannulation 122A, thereby locking the suture 124 in place and preventing it from sliding in the second direction D2.
The cannulation 222 may be circumscribed by an interior wall 226 of the locking ferrule 210. An outer diameter wall 228 of the barrel portion 214 may be smooth or could alternatively include threads, barbs, or other features for facilitating bone fixation.
A plurality of locking barbs 230 may protrude inwardly from the interior wall 226. The locking barbs 230 may therefore occupy at least a portion of the open space of the cannulation 222. The locking barbs 230 may establish a one-way locking mechanism that permits suture 224 to pass through the cannulation 222 in a first direction while preventing the suture(s) from being tensioned or otherwise moved in a second direction.
One or more slots 266 may be formed in the cap portion 212. Each slot 266 may open into the cannulation 222. Each slot 266 may function as a cleat for locking the suture 224 relative to the locking ferrule 210. The size and shape of the slots 266 is not intended to limit this disclosure as is evident from the exemplary design options illustrated in
In an embodiment, the slots 266 do not extend through a side wall 220 of the cap portion 212 (see
In an embodiment, suture 224 may be arranged within the cannulation 222 in a manner that forms a loop 268 in the suture 224 (see, e.g.,
In the embodiments described above, the exemplary locking ferrules include both a cap portion and a barrel portion that are arranged together to provide a top hat-like appearance of the locking ferrule. However, other locking ferrule implementations could exclude the cap portion, and therefore locking ferules that do not exhibit a top hat-like appearance are also contemplated within the scope of this disclosure. For example,
A cannulation 322 may extend through the barrel portion 314 and may establish an internal passageway for accommodating one or more strands of suture 324. The cannulation 322 may be circumscribed by an interior wall 326 of the locking ferrule 310. An outer diameter wall 328 of the barrel portion 314 may be smooth or could alternatively include threads, barbs, or other features for facilitating bone fixation.
A plurality of locking barbs 330 may protrude inwardly from the interior wall 326. The locking barbs 330 may therefore occupy at least a portion of the open space of the cannulation 322. The locking barbs 330 may establish a one-way locking mechanism that permits one or more sutures 324 to pass through the cannulation 322 in a first direction while preventing the suture(s) from being tensioned or otherwise moved in a second direction.
One or more side openings 372 may be formed through the barrel portion 314. Each side opening 372 may open through both the interior wall 326 and the outer diameter wall 328. The side openings 372 are therefore connected to the cannulation 322.
In an embodiment, the suture 324 may be arranged within the cannulation 322 in a manner that forms a loop 368 in the suture 324. The loop 368 can be used to suspend a graft within a bone tunnel or fixate soft tissue or bone, for example. Free ends 370 of the suture 324 may be passed through each side opening 372 and then tensioned to help force the portions of the suture 324 that are passed through the cannulation 322 into increased engagement with the locking barbs 330.
One or more side openings 472 may be formed through the barrel portion 414. Each side opening 472 may open through both the interior wall 426 and the outer diameter wall 428. The side openings 472 are therefore connected to the cannulation 422.
Each side opening 472 may include a plurality of locking barbs 430. The locking barbs 430 may establish a one-way locking mechanism that permits the suture 424 to pass through the side openings 472 in a first direction while preventing the suture(s) from being tensioned or otherwise moved in a second direction. Although not specifically shown in the exemplary embodiment, the cannulation 422 could be provided with additional locking barbs.
Free ends 470 of the suture 424 may be passed through each side opening 472 and then tensioned to lock the suture 424 in place relative to the locking ferrule 410. In an embodiment, the suture 424 may include a plurality of partitions 474 (see
The first and second cannulations 522A, 522B may establish internal passageways for accommodating one or more strands of suture 524 (see
The first cannulation 522A may include a plurality of locking barbs 530. The locking barbs 530 may protrude inwardly from an interior wall 526A that circumscribes the first cannulation 522A. The locking barbs 530 may therefore occupy at least a portion of the open space of the first cannulation 522A. The locking barbs 530 may establish a one-way locking mechanism for locking suture 524 relative to the locking ferrule 510.
The second cannulation 522B may be circumscribed by an interior wall 526B. In an embodiment, the second cannulation 522B excludes locking barbs, and therefore the interior wall 526B can be configured to provide a substantially smooth surface that allows the suture 524 to be shuttled through the locking ferrule 510 prior to being locked in place via the locking barbs 530 of the first cannulation 522A. The suture 524 may be retained relative to the second cannulation 522B by a knot 576.
In another embodiment, the second cannulation 522B includes an additional plurality of locking barbs 530 (see
The surgical button 678 may include a first opening 680 and a second opening 682 formed through a body of the surgical button 678 and separated by a bridge 684. The first and second openings 680, 682 may establish through-passages for accommodating and locking one or more strands of suture 624 relative to the surgical button 678.
The first opening 680 may include a plurality of locking barbs 630. The locking barbs 630 may establish a one-way locking mechanism for locking the suture 624 relative to the surgical button 678. The second opening 682 may exclude locking barbs and therefore provides a substantially smooth surface that allows the suture 624 to be shuttled through the surgical button 678 prior to being locked in place via the locking barbs 630.
The suture 624 may be shuttled through the second opening 682 and then through the first opening 680 of the surgical button 678 using a shuttle device 656. The shuttle device 656 may be a passing wire or another suture, for example. The suture 624 may be passed through an eyelet 658 of the shuttle device 656, and a free end 660 of the shuttle device 656 may then be pulled (in the direction 677) to shuttle the suture 624 through the surgical button 678.
In the illustrated embodiment, the locking barbs 630 are integrally formed features of the body of the surgical button 678. However, the locking barbs 630 could alternatively be provided within a separate locking ferrule 610 that is insertable into the first opening 680 or the second opening 682 of the surgical button 678 (see, e.g.,
The bone plate 786 may include a plurality of openings 788 formed through a plate body of the bone plate 786. The openings 788 may establish through-passages for accommodating other devices, such as suture, screws, etc. and/or for locking one or more strands of suture 724 relative to the bone plate 786.
One or more of the openings 788 may include a plurality of locking barbs 730. The locking barbs 730 may establish a one-way locking mechanism for locking the suture 724 relative to the bone plate 786. The suture 724 may be passed through the opening 788 in a first direction and may be prevented from moving in a second direction by the locking barbs 730.
In an embodiment, the locking barbs 730 may only be provided at select portions of the respective opening, with remaining portions left smooth by omitting the locking barbs (see, e.g., opening identified at 788-2). In another embodiment, at least a portion of the openings 788 of the bone plate 786 may completely omit any locking barbs 730 (see, e.g., openings identified at 788-3 and 788-4).
In the illustrated embodiment, the locking barbs 730 are integrally formed features of the plate body of the bone plate 786. However, the locking barbs 730 could alternatively be provided as part of a separate locking ferrule 710 that is insertable into one of the openings 788 of the bone plate 786 (see, e.g.,
A locking ferrule 810 may be inserted into any one of the openings 888. The locking ferrule 810 may include an engagement portion 890 and an eyelet portion 892. The engagement portion 890 may be configured to connect to the opening 888, such as via a threaded engagement, for example. The eyelet portion 892 may be configured to receive and lock suture 824 relative to the bone plate 886.
The eyelet portion 892 may include a plurality of locking barbs 830. The locking barbs 830 may establish a one-way locking mechanism for locking the suture 824 relative to the bone plate 886. The suture 824 may be passed through the eyelet portion 892 in a first direction and may be prevented from moving in a second direction by the locking barbs 830.
After inserting the locking ferrule 810 into one of the openings 888, the suture 824 may be passed through or around a tissue 894 (e.g., bone, see
The arthroplasty implant 996 may include one or more openings 988 formed through a body of the arthroplasty implant 996. A locking ferrule 910 may be inserted into any one of the openings 988. The locking ferrule 910 may include a cannulation 922 that includes a plurality of locking barbs 930. The locking barbs 930 may establish a one-way locking mechanism for locking the suture 924 relative to the locking ferrule 910.
In an embodiment, the suture 924 may be passed through or around a tissue 994 (e.g., tendon, see
The suture anchor 1098 may additionally include one or more locking ferrules 1010 that may be positioned within an internal bore 1097 of the sheath 1099. Each locking ferrule 1010 may include a cannulation 1022 that includes a first plurality of locking barbs 1030A. The locking barbs 1030A may establish a one-way locking mechanism for locking suture 1024 relative to the locking ferrule 1010. An outer diameter wall 1028 of the locking ferrule 1010 may include a second plurality of barbs 1030B that are configured to engage the internal wall of the sheath 1099 for locking a position of the locking ferrule 1010 within the internal bore 1097.
In an embodiment, the sheath 1099 of the suture anchor 1098 may be inserted into a socket 1095 formed in a bone 1093. The socket 1095 may be a preformed opening formed in the bone 1093 that is sized for receiving the sheath 1099. The suture 1024 may be passed through or around a tissue 1094 (e.g., ligament, tendon, etc., see
A plurality of locking barbs 1130 may protrude inwardly from the interior wall 1126. The locking barbs 1130 may therefore occupy at least a portion of the open space of the cannulation 1122. The locking barbs 1130 may establish a one-way locking mechanism that permits suture 1124 to pass through the cannulation 1122 in a first direction while preventing the suture 1124 from being tensioned or otherwise moved in a second direction.
In an embodiment, the cannulation 1122 may extend along a longitudinal centerline axis B that extends at an oblique angle α relative to a longitudinal centerline axis A of the barrel portion 1114. Arranging the cannulation 1122 at the oblique angle α through the locking ferrule 1110 can help force the suture 1124 into increased engagement with the locking barbs 1130.
The suture locking devices of this disclosure may be utilized for performing various tensionable knotless surgical repairs or other surgical procedures. The suture locking devices provide for tensioning and retensioning suture(s) at various points of the repair, including subsequent to implantation of accompanying fixation devices, thus providing numerous advantages over prior tissue repair systems and techniques.
