The repairs were cyclically loaded at 0.5 Hz from 10 to 200 N, then pulled to failure. Elongation, stiffness, maximum load at failure, and mode of failure were recorded and calculated.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>There were no significant differences in graft elongation or stiffness among the 3 techniques ( P &gt; .37 and P &gt; .26, respectively). Maximum load to failure was significantly greater in technique 1 (mean \u00b1 SD, 427.85 \u00b1 119.70 N) than technique 3 (319.5 \u00b1 57.60 N) ( P = 0.024).
