Methods of this disclosure are contemplated for preparing a graft at a site outside of a hospital setting, storing offsite, and/or later transporting to the hospital for use with a patient. ## Claims ### Claim 1 A method for preparing a graft for a patient at a location that is separate from an operating room or a hospital, the method comprising: suturing a first proximal end and a first distal end of a tendon; positioning a first implant between the first proximal and first distal ends, the first implant comprising a loop oriented about the graft between the proximal and distal ends; then folding the first distal or first proximal end of the graft about the loop of the first implant until the first distal or proximal end are in contact or adjacent the other of the ends, wherein a second proximal end and a second distal end are now formed by the folding of the graft, the second proximal end being adjacent the first proximal and distal ends; then positioning a second implant between the second proximal and second distal ends, the second implant comprising a loop oriented about the graft between the second proximal and distal ends; then folding the second distal end of the graft about the loop of the second implant until the second distal end contacts or is adjacent the first proximal and/or distal end; then moving the second distal end away from the first proximal and/or distal end; then distally moving the first implant towards the second implant and orienting downward the loop of the first implant, the first implant being distally moved between folded segments of the graft; then stitching and/or suturing portions of second proximal and/or distal ends together. ### Claim 2 (depends on 1) The method according to claim 1, further comprising then transporting the prepared graft to a hospital. ### Claim 3 (depends on 2) The method according to claim 2, further comprising: administering cephalexin to the patient; and then reconstructing a treatment site of interest of a patient with the prepared graft. ### Claim 4 (depends on 3) The method according to claim 3, wherein the cephalexin is orally administered using a capsule equivalent to 250 mg cephalexin. ### Claim 5 (depends on 3) The method according to claim 3, wherein the cephalexin is orally administered using a capsule equivalent to 500 mg cephalexin. ### Claim 6 (depends on 3) The method according to claim 3, wherein the cephalexin is orally administered using a capsule equivalent to 700 mg cephalexin. ### Claim 7 (depends on 2) The method according to claim 2, further comprising: administering cefazolin via intravenous therapy, and/or Clindamycin to the patient; and then reconstructing a treatment site of interest of the patient with the prepared graft. ### Claim 8 (depends on 1) The method according to claim 1, wherein a duration of time to perform each step of the method is approximately 30 minutes. ### Claim 9 (depends on 1) The method according to claim 1, wherein a step of providing the graft relates to one or more tendons from the semitendinosus, the gracilis, the anterior tibialis, or the posterior tibialis. ### Claim 10 (depends on 1) The method according to claim 1, wherein a step of providing the graft relates to one or more tendons from the peroneus longus. ### Claim 11 (depends on 1) The method according to claim 1, wherein the step of suturing the first proximal end and suturing the first distal end is implemented using the Krackow method. ### Claim 12 (depends on 1) The method according to claim 1, wherein the step of suturing the first proximal end and suturing the first distal end is implemented using suture tape of 1.5 mm and/or 2.0 mm. ### Claim 13 (depends on 1) The method according to claim 1, wherein the step of moving the second distal end away from the first proximal and/or distal end is implemented by pivoting the second distal end about a pivot point between the second distal end and the first proximal and/or distal end. ### Claim 14 (depends on 1) The method according to claim 1, wherein the step of moving the second distal end away from the first proximal and/or distal end is implemented by pivoting the second distal end a predetermined distance away from the first proximal and/or distal end, the predetermined distance being greater than a width of the first implant. ### Claim 15 (depends on 1) The method according to claim 1, wherein the step of moving the second distal end away from the first proximal and/or distal end is implemented by pivoting the second distal end a predetermined distance away from the first proximal and/or distal end, the predetermined distance being greater than a thickness of the first implant. ### Claim 16 (depends on 1) The method according to claim 1, wherein the first and second implants comprise one or more durable elongate ropes constructed from a high tension biocompatible material. ### Claim 17 (depends on 1) The method according to claim 1, wherein the step of orienting downward the loop of the first implant comprises reorienting the first implant at least 90 degrees until being positioned by having its loop angled substantially downward. ### Claim 18 (depends on 1) The method according to claim 1, wherein the step of stitching and/or suturing portions of second proximal and/or distal ends together further comprises implanting at least five half-stiches. ### Claim 19 (depends on 1) The method according to claim 1, wherein the graft measures 230 mm-260 mm length by 8.5 mm 10.0 mm. ### Claim 20 (depends on 1) A graft prepared according to claim 1, wherein the first and second implants comprise one or more durable elongate ropes constructed from a biocompatible material.
