前十字韧带(ACL)断裂与重建(ACLR)后的运动学和动力学变化是理解机械破坏负荷的基础，因为它促进了创伤后骨关节炎的发展。这些分析忽略了肌肉活动的潜在贡献，因为它与关节负荷环境有关。在前交叉韧带损伤后，男性和女性都表现出独特的膝关节运动学和动力学。这项研究的目的是对这些个体进行性别特异性分析，以探索前交叉韧带断裂后步态中的肌肉活动时间。受试者39人(女性12人，男性27人)。分别在术前、术后和ACLR术后6个月进行步态肌肉活动评估。对表面肌电信号数据进行评估，以确定七块肌肉的时间(例如，肌肉活动开始(ON)和结束(OFF)的时间)：股外侧肌和内侧肌(VL，Vm)、外侧和内侧腿筋(Lh，MH)、外侧和内侧腓肠肌(Lg，MG)和比目鱼肌(SOL)。带有广义估计方程的一般线性模型检测了肢体和时间对肌肉活动计时的影响。男性在术前和术后出现了更多的肢体不对称，其中VL开(p<；0.001)和关(p=0.007)，Vm开和关(p<；0.001)和MH关(p<；0.001)，但所有的肢体差异在ACLL术后6个月都消失了。随着时间的推移，男性肌肉活动的变化在两条腿上都很普遍。女性患者术前肢体间无明显差异，仅患肢VL Off(p=0.027)、Vm Off(p=0.003)和Lh Off(p<；0.038)随时间变化。我们的数据表明，肢体间肌肉活动在不同时间点的差异以及在物理治疗过程中肌肉活动时间的变化是性别特有的。男性在不同时间点的肢体间肌肉活动差异更大，而女性在术前物理治疗前后的不对称性较少。这些数据支持，在评估ACLR术后的生物力学变化时，应考虑性别差异的适应性。
Kinematic and kinetic changes following anterior cruciate ligament (ACL) rupture and reconstruction (ACLR) have been fundamental to the understanding of mechanical disrupted load as it contributes to the development of posttraumatic osteoarthritis. These analyses overlook the potential contribution of muscle activity as it relates to the joint loading environment. Males and females classified as non-copers present with unique knee kinematics and kinetics after ACL injury. The purpose of this study was to perform sex-specific analyses in these individuals to explore muscle activity timing during gait after ACL rupture. Thirty-nine participants (12 females, 27 males) were enrolled. Muscle activity during gait was evaluated before and after pre-operative physical therapy, and six months after ACLR. Surface electromyography data were evaluated to determine timing (e.g., the time the muscle activity begins (‘On’) and ends (‘Off’)) for seven muscles: vastus lateralis and medialis (VL, VM), lateral and medial hamstrings (LH, MH), lateral and medial gastrocnemius (LG, MG), and soleus (SOL). General linear models with generalized estimating equations detected the effects of limb and time for muscle activity timing. Males presented with more limb asymmetries before and after pre-operative PT in the VL On (p < 0.001) and Off (p = 0.007), VM On and Off (p < 0.001), and MH off (p < 0.001), but all limb differences resolved by six months post ACLR. Changes in muscle activity in males were pervasive over time in both limbs. Females presented with no interlimb differences pre-operatively, and only involved limb VL off (p = 0.027) and VM off (p = 0.003) and the LH off in both limbs (p < 0.038) changed over time. Our data indicate that inter-limb differences in muscle activity across time points and changes in muscle activity timing over the course of physical therapy were sex specific. Males presented with more inter-limb differences in muscle activity across time points, and females presented with fewer asymmetries before and after pre-operative physical therapy. These data support that sex-specific adaptations should be taken into consideration when assessing biomechanical changes after ACLR.
