摘要：

文题释义：

前交叉韧带重建：是一种用于治疗前交叉韧带断裂或损伤的手术方法。前交叉韧带是膝关节内重要的稳定结构，对维持膝关节的稳定性和正常运动功能起着关键作用。当韧带发生断裂或严重损伤后，难以自行愈合，需通过自体或异体肌腱等替代物，在膝关节内重建稳定结构，以恢复膝关节的稳定性。
髋关节肌肉力量：是指髋部周围肌肉能够产生的力量，其对维持膝关节的稳定性和正常功能起着重要作用。前交叉韧带重建后膝关节的稳定性会受到影响，而髋关节肌肉力量不仅可以提高髋关节的稳定性，其在改善步态和运动模式等方面也具有重要作用。因此，针对髋关节肌肉力量的训练是前交叉韧带重建术后康复的关键环节之一，对于恢复患者正常的关节功能、重返运动均具有重要意义。


摘要
背景：膝关节功能和肌肉力量的恢复是前交叉韧带重建后的康复重点，但下肢关节间异常的力学模式可能会改变运动中的下肢生物力学特征，增加前交叉韧带损伤的风险。
目的：探究前交叉韧带重建患者手术2年后单腿落地时双侧下肢生物力学特征及其与髋关节肌肉力量的相关性。
方法：招募前交叉韧带重建术受试者23例，采用Qualisys三维运动捕捉系统和AMTI三维测力台分别采集单腿落地时双侧下肢的运动学和动力学数据，采用Biodex等速肌力测试系统采集60 (°)/s角速度下双侧髋、膝关节的肌肉力量；采用配对样本t检验对比双侧下肢关节生物力学特征及60 (°)/s角速度下双侧髋、膝关节等速肌力的差异，采用皮尔逊相关性分析探究单腿落地测试中的动力学数据与髋、膝关节等速肌力的相关性。
结果与结论：①在单腿落地时，前交叉韧带重建患者术侧表现出较小的触地时刻膝伸展角度、膝屈/伸活动度、垂直地面反作用力、髋伸展、髋外展及膝伸展力矩峰值，较大的触地时刻髋屈曲角度、髋屈/伸活动度；②在60 (°)/s角速度下，术侧髋外展、髋伸展、膝屈曲及膝伸展肌力矩显著减小；③术侧腿落地时术侧的垂直地面反作用力峰值、髋关节伸展力矩峰值与髋外展肌力显著相关，而术侧腿落地时术侧膝关节伸展力矩峰值与髋外展、屈曲、伸展肌力显著相关；④结果表明前交叉韧带重建患者在手术2年后术侧肌力并未恢复至健侧水平，这可能与手术引发的神经抑制相关；患者在单腿落地时采取募集髋关节肌力的缓冲策略主动降低垂直地面反作用力，但术侧较小的髋外展力矩峰值也降低了膝关节冠状面的稳定性；因此，建议前交叉韧带重建术后2年持续进行髋、膝关节肌力训练，尤其是髋外展、伸展和膝屈曲、伸展肌力，同时针对性地引入神经肌肉训练和运动技术指导，以改善运动时的神经肌肉控制能力，避免不良代偿策略对运动的负面影响。

Abstract: BACKGROUND: Recovery of knee joint function and muscle strength is a key focus of rehabilitation after anterior cruciate ligament reconstruction. However, abnormal inter-joint mechanical patterns of the lower limbs may alter lower limb biomechanics during movement and increase the risk of anterior cruciate ligament injury. 
OBJECTIVE: To explore the lower limb biomechanical characteristics of anterior cruciate ligament reconstruction patients during single-leg landing 2 years after surgery, and their correlation with hip joint muscle strength. 
METHODS: Totally 23 subjects who underwent anterior cruciate ligament reconstruction were randomly recruited. The Qualisys three-dimensional motion capture system and AMTI three-dimensional force platforms were used to capture kinematic and kinetic data of both lower limbs during single-leg landing. The Biodex isokinetic muscle testing system was used to measure muscle strength of both hip and knee joints at an angular velocity of 60°/s. Paired sample t-tests were used to compare the biomechanical characteristics of bilateral lower limb joints and the isokinetic muscle strength of the hip and knee joints at 60°/s. Pearson correlation analysis was employed to examine the correlation between kinetic data from the single-leg landing test and the isokinetic muscle strength of the hip and knee. 
RESULTS AND CONCLUSION: (1) At the moment of single-leg landing, patients who had undergone anterior cruciate ligament reconstruction on the affected side showed smaller knee extension angles, smaller ranges of knee flexion/extension motion, smaller vertical ground reaction forces, smaller peak moments of hip extension, hip abduction, and knee extension, and larger hip extension angles and larger ranges of hip flexion/extension motion at the time of contact. (2) During angular movement at 60°/s, the muscle strength of the operated side for hip abduction, hip extension, knee flexion, and knee extension was significantly lower. (3) During single-leg landing, the peak vertical ground reaction force on the operated side was significantly related to the peak hip extension torque and hip abduction strength, while the peak knee extension torque on the operated side was significantly related to the strength of hip abduction, flexion, and extension. (4) The results showed that two years post-anterior cruciate ligament reconstruction, patients fail to regain equal strength on the operated side, possibly due to neural inhibition induced by surgery. To reduce vertical ground reaction force during single-leg landing, they use a hip-muscle-powered buffering strategy. Yet, the operated side's lower hip abduction torque peak also compromises coronal-plane knee stability. Therefore, it is recommended that after anterior cruciate ligament reconstruction, patients continue to do hip and knee strengthening exercises for 2 years, focusing on hip abduction, extension, and knee flexion and extension while specifically including neuromuscular training and sport-specific technique guidance. This will enhance neuromuscular control during movement and prevent negative impacts from faulty movement patterns.
