Seven separate tibialis anterior grafts were then prepared by suturing a running-locking No. 2 suture on each tail of the graft. Three specimens had fixation of the graft to the acetabulum using an adjustable cortical suspension suture button; the remaining 4 were fixed to the acetabulum using a knotless suture anchor. Specimens were then mounted onto a custom jig within a mechanical test frame to allow for the in-line pull of the graft fixation construct. After a preload of 5 N, each specimen was loaded to failure at 0.5 mm\/s. Stiffness and load to failure were measured for each specimen construct.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>Suture button fixation had a higher mean load to failure when compared with the knotless anchor fixation method (mean \u00b1 SD, 438.1 \u00b1 114.3 vs 195.9 \u00b1 50.0 N; P = .01).
