The proposed systems and methods may utilize one or more soft suture staple assemblies and one or more knotless suture anchors for reducing and fixating tissue to bone. The soft suture staple assemblies and knotless suture anchors may be used as part of a multi-row fixation technique for providing a desired area of footprint compression over top of the tissue. ## Claims ### Claim 1 A surgical method, comprising: inserting a soft suture staple assembly through a tissue and into a bone that underlies the tissue, wherein the soft suture staple assembly includes a first suture sheath, a second suture sheath, and a suture routed through a bore of each of the first suture sheath and the second suture sheath to form a closed loop that interconnects the first suture sheath and the second suture sheath, wherein inserting the soft suture staple assembly includes simultaneously inserting the first suture sheath and the second suture sheath of the soft suture staple assembly through the tissue and into the bone; inserting a knotless suture anchor into the bone at a position that is lateral to the soft suture staple assembly; connecting a suture of the knotless suture anchor to a portion of the closed loop that extends over top of the tissue; and securing the suture back to the knotless suture anchor. ### Claim 2 (depends on 1) The surgical method as recited in claim 1, wherein the portion of the closed loop includes a mattress stitch that extends over top of the tissue. ### Claim 3 (depends on 2) The surgical method as recited in claim 2, wherein the mattress stitch is part of the suture that is routed through the first suture sheath and the second suture sheath of the soft suture staple assembly. ### Claim 4 (depends on 2) The surgical method as recited in claim 2, wherein the portion of the closed loop includes a first mattress stitch and a second mattress stitch that extend over top of the tissue. ### Claim 5 (depends on 1) The surgical method as recited in claim 1, wherein securing the suture back to the knotless suture anchor includes: splicing the suture through itself to establish a suture loop that is looped around the portion. ### Claim 6 (depends on 5) The surgical method as recited in claim 5, wherein securing the suture back to the knotless suture anchor includes: tensioning the suture to further reduce the portion into place and provide a desired area of footprint compression over top of the tissue, wherein tensioning the suture configures the portion in a bridging pattern over top of the tissue. ### Claim 7 (depends on 1) The surgical method as recited in claim 1, wherein connecting the suture of the knotless suture anchor to the portion of the closed loop includes: looping the suture around at least one mattress stitch of the closed loop. ### Claim 8 (depends on 1) The surgical method as recited in claim 1, wherein connecting the suture of the knotless suture anchor to the portion of the closed loop includes: passing the suture through at least one eyelet of the portion of closed loop. ### Claim 9 (depends on 1) The surgical method as recited in claim 1, wherein the soft suture staple assembly is comprised exclusively of soft, suture-based materials. ### Claim 10 A surgical method, comprising: inserting a soft suture staple assembly through a tissue and into a bone, wherein the soft suture staple assembly includes a first sheath, a second suture sheath, and a suture routed through a bore of each of the first suture sheath and the second suture sheath to form a closed loop that interconnects the first suture sheath and the second suture sheath; connecting a suture of a knotless suture anchor to a portion of the closed loop that extends over top of the tissue; tensioning the suture to compress the portion of the closed loop against the tissue; and fixating the suture relative to the bone with the knotless suture anchor. ### Claim 11 (depends on 10) The surgical method as recited in claim 10, wherein fixating the suture relative to the bone with the knotless suture anchor includes: inserting the knotless suture anchor into the bone at a position that is lateral to the soft suture staple assembly. ### Claim 12 (depends on 11) The surgical method as recited in claim 11, wherein the knotless suture anchor is inserted into the bone before connecting the suture to the portion of the closed loop. ### Claim 13 (depends on 12) The surgical method as recited in claim 12, wherein connecting the suture to the portion of the closed loop includes: splicing the suture through itself to establish a suture loop that is looped around the portion of the closed loop. ### Claim 14 (depends on 11) The surgical method as recited in claim 11, wherein the knotless suture anchor is inserted into the bone after connecting the suture to the portion of the closed loop. ### Claim 15 (depends on 14) The surgical method as recited in claim 14, wherein fixating the suture relative to the bone with the knotless suture anchor includes: feeding the suture through an eyelet of the knotless suture anchor; positioning the eyelet within a socket formed in the bone; tensioning the suture; and moving an anchor body of the knotless suture anchor toward the eyelet within the socket, thereby trapping the suture between the bone and the anchor body. ### Claim 16 (depends on 15) The surgical method as recited in claim 15, wherein tensioning the suture configures the portion of the closed loop in a bridging pattern over top of the tissue. ### Claim 17 (depends on 10) The surgical method as recited in claim 10, wherein tensioning the suture configures the portion of the closed loop in a bridging pattern over top of the tissue. ### Claim 18 (depends on 10) The surgical method as recited in claim 10, wherein the closed loop includes a mattress stitch that is part of the suture that is routed through the first suture sheath and the second suture sheath of the soft suture staple assembly. ### Claim 19 A surgical method, comprising: inserting a first suture sheath of a soft suture staple assembly through a tissue and into a bone that underlies the tissue, wherein the soft suture staple assembly includes the first suture sheath, a second suture sheath, and a first suture routed through a bore of each of the first sheath and the second sheath to form a closed loop that interconnects the first suture sheath and the second suture sheath; after inserting the first suture sheath, inserting the second suture sheath of the soft suture staple assembly through the tissue and into the bone, wherein, after inserting the first suture sheath and the second suture sheath through the tissue and into the bone, a portion of the closed loop extends over top of the tissue; inserting a knotless suture anchor into the bone at a position that is lateral to the soft suture staple assembly; looping a second suture of the knotless suture anchor around the portion of the closed loop that extends over top of the tissue; and securing the second suture back to the knotless suture anchor.
