前交叉韧带重建后神经肌肉适应的持久性尚不清楚。本研究的目的是比较双侧肌肉共同收缩指数，时间达到峰值地面反作用力，肌肉开始重建后10-15年的前交叉韧带重建受试者与匹配的未受伤的对照组在单腿跳跃着陆的时间。招募了9名健康对照和9名重建受试者。进行临床和功能膝关节检查。测量双侧下肢共收缩指数、地面反作用力峰值时间和肌肉起始时间。采用非配对t检验评估临床和功能结局的差异，并采用混合模型重复测量来检查肌电图测量中组、肢体和相互作用项的影响。89%的对照膝关节临床上“正常”，而只有33%的重建膝关节是“正常”的。前交叉韧带重建的受试者倾向于实现较短的功能跳跃距离，但表现出对称的下肢肌电图测量结果与对照组无差异，除了股二头肌激活在地面接触前双侧延迟，但在着陆的损伤风险阶段更大。除腘绳肌激活外，下肢肌电图测量在韧带重建和匹配的对照受试者之间基本相似，这与临床结果相反。这一结果在长期随访中对神经肌肉功能的重要性提出了质疑，但也提出了关于对称性和损伤前风险的新问题。
The permanence of neuromuscular adaptations following anterior cruciate ligament reconstruction is not known. The aim of this study was to compare bilateral muscle co-contraction indices, time to peak ground reaction force, and timing of muscle onset between anterior cruciate ligament reconstruction subjects 10–15 years post reconstruction with those of matched uninjured controls during a one-leg hop landing. Nine healthy controls and 9 reconstruction subjects were recruited. Clinical and functional knee exams were administered. Lower limb co-contraction indices, time to peak ground reaction force, and muscle onset times were measured bilaterally. Differences in clinical and functional outcomes were assessed with unpaired t-tests, and mixed model repeated measures were used to examine effects of group, limb and interaction terms in electromyography measures. 89% of control knees were clinically “normal”, whereas only 33% of reconstructed knees were “normal”. Anterior cruciate ligament-reconstructed subjects tended to achieve shorter functional hop distances but demonstrated symmetrical lower limb electromyography measures that were no different from those of controls’ with the exception that biceps femoris activation was delayed bilaterally prior to ground contact but was greater during the injury risk phase of landing. With the exception of hamstring activation, lower limb electromyography measures were largely similar between ligament-reconstructed and matched control subjects, which was in contrast to the clinical findings. This result brings into question the significance of neuromuscular function at this long-term follow-up but raises new questions regarding the role of symmetry and pre-injury risk.
