The purpose of this study was to compare pre\u2010 and post\u2010landing muscle activation in ACL\u2010D individuals and uninjured controls during normal and surprise landings. Nineteen ACL\u2010D and 17 uninjured volunteered. Participants performed repeated single leg landings from 30 and 15\u00a0cm heights. During 15\u00a0cm landings, a single surprise landing was performed where participants unexpectedly fell through a false surface at 15\u00a0cm to the solid floor a further 15\u00a0cm below. Electromyography (EMG) amplitude from vastus lateralis (VL), lateral hamstrings (LH), and soleus (Sol) was recorded. Pre\u2010landing (\u221260 to 0\u00a0ms), post\u2010landing short latency (31\u201060\u00a0ms), and post\u2010landing medium latency (61\u201090\u00a0ms) periods were examined. Comparisons in EMG amplitudes were made across limbs (ACL\u2010D, ACL intact, and control) in 30\u00a0cm landings. Additionally, the ratio of EMG amplitude in surprise:30\u00a0cm normal landings was analyzed. Post\u2010landing LH EMG was reduced in the ACL\u2010D compared to control limbs at short latencies (\n                    <jats:italic>P<\/jats:italic>\n                    \u00a0&lt;\u00a00.05). Post\u2010landing VL EMG was reduced in the ACL\u2010D and ACL intact compared to the control limb at both latencies (\n                    <jats:italic>P<\/jats:italic>\n                    \u00a0&lt;\u00a00.05). Surprise landings notably increased post\u2010landing EMG in all muscles, across all limbs (\n                    <jats:italic>P<\/jats:italic>\n                    \u00a0&lt;\u00a00.001). However, the gain in VL EMG was significantly greater in ACL\u2010D and ACL intact limbs (\n                    <jats:italic>P<\/jats:italic>\n                    \u00a0&lt;\u00a00.05). These changes in neuromuscular control of ACL\u2010D individuals during expected and surprise landings may have important implications for rehabilitation, instability, and the risk of secondary injury.\n
