Both groups followed the same standardised rehabilitation protocol, with the braced group using a rigid orthosis for 6 weeks postoperatively. Functional outcomes were assessed through 3D kinematic analysis using inertial measurement units during walking, running, countermovement jumps (CMJ) and drop jumps (DJ) at 6\u2010 and 12\u2010month postoperatively. Statistical parametric mapping (SPM) was used to analyse time\u2010continuous biomechanical data.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>At 6 months, the braced group demonstrated a significant deficit in knee extension during push\u2010off (22.7%\u201334.5% of the running step, max effect size [ES]\u2009=\u2009\u20130.60, min ES\u2009=\u2009\u20130.69) and reduced ankle extension during the push\u2010off phase of DJs (98.5%\u201399.9% of the loading phase, max ES\u2009=\u2009\u20130.55, min ES\u2009=\u2009\u20130.56).
