背景资料：异常的行走步态和跳跃着陆生物力学可能会影响创伤后骨关节炎的发展，并增加第二次前交叉韧带损伤的风险。它仍然是未知的，如果个人谁表现出改变行走步态生物力学表现出类似的改变生物力学在跳跃着陆。我们的目的是确定单侧前交叉韧带重建患者的行走步态和跳跃着陆任务之间的膝关节生物力学峰值和肢体对称性指数之间的相关性。35个人（74%为妇女，22.1 [3.4]岁，25 [3.89] kg/m2），前交叉韧带重建，进行5次自选行走步态和跳跃着陆试验。峰值动力学和运动学提取的第一个50%的立场阶段在步行步态和第一个100毫秒后，地面接触跳跃着陆。Pearson积差（r）和斯皮尔曼的Rho（p）分析用于评价结果测量之间的关系。先验地设定显著性（P
Background: Aberrant walking-gait and jump-landing biomechanics may influence the development of post traumatic osteoarthritis and increase the risk of a second anterior cruciate ligament injury, respectively. It remains unknown if individuals who demonstrate altered walking-gait biomechanics demonstrate similar altered biomechanics during jump-landing. Our aim was to determine associations in peak knee biomechanics and limb symmetry indices between walking-gait and jump-landing tasks in individuals with a unilateral anterior cruciate ligament reconstruction.Methods: Thirty-five individuals (74% women, 22.1 [3.4] years old, 25 [3.89] kg/m(2)) with an anterior cruciate ligament reconstruction performed 5-trials of self-selected walking-gait and jump-landing. Peak kinetics and kinematics were extracted from the first 50% of stance phase during walking-gait and first 100 ms following ground contact for jump-landing. Pearson product-moment (r) and Spearman's Rho (p) analyses were used to evaluate relationships between outcome measures. Significance was set a priori (P
