Players were excluded if they had previous ACL injury. Medial and lateral PTS, delta PTS (lateral\u2013medial PTS), TTTG, static axial TF rotation and knee flexion were independently measured by two musculoskeletal radiologists, and multivariable regression and generalized linear mixed\u2010effects models were used to assess the effects of PTS, time and LET on axial TF rotation and TTTG.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Fifty\u2010six professional soccer players (mean age 23.1\u2009\u00b1\u20094.4 years) were included, of whom 41 (73.2%) underwent concomitant LET.
