However, concerns remain that LET may overconstrain the lateral compartment, alter gait biomechanics, and contribute to degenerative changes, especially in pediatric patients.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Hypothesis\/Purpose:<\/jats:title>\n                    <jats:p>The purpose of this study was to compare 3-dimensional (3D) knee kinematics during gait between pediatric patients who underwent ACLR with LET (ACLR+LET) and those who underwent isolated ACLR (iACLR). It was hypothesized that patients with ACLR+LET would show modified postoperative gait biomechanics compared to those with iACLR, namely decreased tibial internal rotation and increased valgus during the unloading phase.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Study Design:<\/jats:title>\n                    <jats:p>Cohort study; Level of evidence, 3.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>This retrospective study included pediatric patients (\u226418 years of age) who underwent ACLR with or without LET between January 2023 and January 2026.
