One of each pair of shoulders was randomly assigned to receive the classic or congruent-arc technique. Coracoid and glenoid anatomic measurements were collected before biomechanical testing. A tensile force was applied through the conjoined tendon to replicate forces experienced by the coracoid graft in the early postoperative period, and the failure load was determined for each specimen.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      The mean \u00b1 SD surface area available for fixation was 263 \u00b1 63 mm\n                      <jats:sup>2<\/jats:sup>\n                      in the classic technique compared with 177 \u00b1 63 mm\n                      <jats:sup>2<\/jats:sup>\n                      in the congruent-arc group ( P &lt; .001). 36% of the glenoid width was recreated in the classic group and 50% in the congruent-arc group ( P &lt; .001). The congruent-arc technique resulted in a significantly lower ( P = .005) mean failure load (239 \u00b1 91 N) compared with the classic technique (303 \u00b1 114 N). Failure load was significantly higher in males ( P = .037); male specimens had a mean failure load of 344 \u00b1 122 N for the classic technique and 289 \u00b1 73 N for the congruent-arc technique, and females had a mean failure load of 266 \u00b1 98 N and 194 \u00b1 84 N, respectively.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>In this biomechanical model, the classic technique of the Latarjet procedure provided a greater surface area for healing to the glenoid and superior initial fixation when compared with the congruent-arc technique.
