Matched-pair randomization was performed, with each side per specimen assigned to 1 of 2 groups. In group 1, the ACL was sectioned, followed by the anterolateral ligament (ALL); in group 2, the ACL was sectioned, followed by sequential sectioning of the posterolateral meniscocapsular complex (PLMCC) and posteromedial meniscocapsular complex (PMMCC). The primary outcome was the change in relative tibial IR during a simulated pivot-shift test with 5 N\u00b7m of IR torque and 8.9 N of valgus force. The secondary outcomes were the International Knee Documentation Committee grade in the pivot-shift test and the incidence of the grade 3 pivot shift.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>In group 1, compared with baseline, the change in relative tibial IR at 0\u00b0 of knee flexion was 1.4\u00b0 (95% CI, \u20130.1\u00b0 to 2.9\u00b0; P = .052) after ALL release. In group 2, it was 2.5\u00b0 (95% CI, 0.4\u00b0 to 4.8\u00b0; P = .007) after PLMCC release and 4.1\u00b0 (95% CI, 0.5\u00b0 to 7.8\u00b0; P = .017) after combined PLMCC and PMMCC release. Combined PLMCC and PMMCC release resulted in greater change of tibial IR with statistical significance at 0\u00b0, 15\u00b0, and 30\u00b0 of knee flexion ( P = .008, .057, and .004, respectively) compared with ALL release. The incidence of grade 3 pivot shifts was 10% in group 1 and 90% in group 2.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n
