A total of 356 of these patients were randomized at centers participating in the functional assessments. Our primary outcome was Limb Symmetry Index, calculated using a series of 4\u2010hop tests at 6, 12, and 24 months postoperatively. Secondary outcome measures included pain, patient\u2010reported function, and isokinetic strength testing.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      We found no statistically significant difference in the proportion of patients either unwilling or unfit to complete the hop testing in the ACLR alone or ACLR with LET group at 6 months (40 vs 40 respectively;\n                      <jats:italic>P<\/jats:italic>\n                      \u00a0= 1.00), 12 months (25 vs 27;\n                      <jats:italic>P<\/jats:italic>\n                      \u00a0= .76), and 24 months (21 vs 23;\n                      <jats:italic>P<\/jats:italic>\n                      \u00a0= .87). Of those who completed hop testing, there were no statistically significant differences between groups in Limb Symmetry Index at 6, 12, or 24 months. Self\u2010reported function (Lower Extremity Functional Score) significantly favored the ACLR alone group at 3 (\n                      <jats:italic>P<\/jats:italic>\n                      \u00a0= .01) and 6 months (\n                      <jats:italic>P<\/jats:italic>\n                      \u00a0= .02) postoperative but was similar by 12 months postoperative. Pain scores (P4) also showed a statistically significant difference in favor of the ACL alone group, but this also resolved by 6 months. Quadriceps peak torque (\n                      <jats:italic>P<\/jats:italic>\n                      \u00a0= .03) and average power (\n                      <jats:italic>P<\/jats:italic>\n                      \u00a0= .01) were also significantly different in favor of the ACLR alone group at 6 months postoperative; however, these were similar between groups by 12 months postoperative (\n                      <jats:italic>P<\/jats:italic>\n                      \u00a0= .11 and\n                      <jats:italic>P<\/jats:italic>\n                      \u00a0= .32, respectively).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>The addition of a LET to ACLR results in slightly increased pain, a mild reduction in quadriceps strength, and reduced subjective functional recovery up to 6 months postoperatively.
