背景资料：最近的研究表明，与健康对照组相比，前交叉韧带重建患者在行走步态期间表现出增加的峰值膝关节内收力矩。膝关节内收力矩峰值增加被认为是膝关节骨关节炎退变的潜在机制。该领域的少数研究没有考虑专门的女性前交叉韧带重建组。本研究验证了女性前交叉韧带重建患者的膝关节内收力矩峰值高于对照组的假设。方法：在实验室中以自选的速度进行了10次15 m步行试验，比较了一组前交叉韧带重建女性和一组女性活动匹配对照组在步行过程中的膝关节内收力矩峰值。前交叉韧带重建组的峰值膝关节内收力矩较低（N = 17，M = 0.31 Nm/kg中心点m，SD = 0.08）（N = 17，M = 0.41 Nm/kg中心点m，SD = 0.12; t（32）= 2.483，p = 0.010，单侧，eta平方效应量= 0.16）。解释：一组女性前交叉韧带重建受试者没有表现出步态特征，而步态特征被认为与以下因素有关：膝关节骨性关节炎的发展，并已被证明存在于男性和混合性别的前交叉韧带重建人群以前。(C)2013爱思唯尔有限公司保留所有权利。
Background: Recent work has shown that anterior cruciate ligament reconstructed patients exhibit an increased peak knee adduction moment during walking gait compared to healthy controls. An increased peak knee adduction moment has been suggested to be a potential mechanism of degeneration for knee osteoarthritis. The few studies in this area have not considered an exclusively female anterior cruciate ligament reconstructed group. This study tested the hypothesis that female anterior cruciate ligament-reconstructed patients would have higher peak knee adduction moments than controls.Methods: Peak knee adduction moment during walking was compared between a group of anterior cruciate ligament reconstructed females and a group of female activity matched controls over ten 15 m walking trials in a laboratory at a self-selected pace.Findings: Peak knee adduction moment was lower for the anterior cruciate ligament reconstructed group (N = 17, M = 0.31 Nm/kg center dot m, SD = 0.08) than for the control group (N = 17, M = 0.41 Nm/kg center dot m, SD = 0.12; t(32) = 2.483, p = 0.010, one-tailed, eta squared effect size = 0.16).Interpretation: A group of female anterior cruciate ligament reconstructed subjects did not exhibit a gait characteristic which has been suggested to be associated with knee osteoarthritis development and has been shown to be present in male and mixed sex anterior cruciate ligament reconstructed populations previously.
