Each subject performed the following exercises: running (run pelvic drop [RPD]), single\u2010leg drop jump and single\u2010leg hop, with 3D analysis synchronised to force platforms. Isometric abduction strength was assessed using the VALD system. Binary and ordinal logistic analyses (likelihood ratio [LR] type II test, false discovery rate [FDR] correction) identified predictors of proximal instability on the operated and contralateral sides.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      On the operated side, pelvic and trunk oscillations were the main predictors of greater pelvic drop (LR\n                      <jats:italic>\u03c7<\/jats:italic>\n                      \u00b2\u2009=\u200996\u2013174,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.001), with less knee flexion.

The isometric strength of the GM and quadriceps showed no significant associations with RPD except for the knee flexors that showed a modest effect on RPD (LR\n                      <jats:italic>\u03c7<\/jats:italic>\n                      \u00b2\u2009=\u20096.09\/6.4,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009\u2248\u20090.013\/0.04).
