前交叉韧带（ACL）是体育活动中最常见的膝关节韧带损伤。受伤后，大多数人在日常活动中都会出现膝关节让位的情况（非患者）。非coppe患者表现出不对称的股四头肌力量和运动模式，这可能对膝关节的完整性产生长期有害影响。本研究的目的是确定非手术患者是否在术后两年内解决了他们的力量和运动不对称。招募26名非手术患者进行术前股四头肌力量测试和三维步态分析。受试者接受手术重建韧带，然后进行物理治疗，重点是恢复正常的活动范围、股四头肌力量和功能。手术后6个月和2年，受试者返回进行股四头肌力量测试和步态分析。急性损伤后，四肢之间的股四头肌力量不对称，但在手术后6个月消退。不对称的膝关节角度、膝关节力矩、膝关节和髋关节力量分布也在受伤后被观察到，并且在手术后6个月持续存在，尽管受试者获得了对称的股四头肌力量。手术后两年，受累肢体的股四头肌力量继续改善，大多数运动学和动力学不对称得到解决。这些发现表明，足够的股四头肌力量并不能立即解决非铜的步态不对称。他们还表明，在前交叉韧带重建后很长一段时间内，非手术者有能力改善他们的股四头肌力量和步态对称性。
The anterior cruciate ligament (ACL) is the most commonly-injured knee ligament during sporting activities. After injury, most individuals experience episodes of the knee giving way during daily activities (non-copers). Non-copers demonstrate asymmetrical quadriceps strength and movement patterns which could have long-term deleterious effects on the integrity of the knee joint. The purpose of this study was to determine if non-copers resolve their strength and movement asymmetries within two years after surgery. 26 non-copers were recruited to undergo pre-operative quadriceps strength testing and 3-dimensional gait analysis. Subjects underwent surgery to reconstruct the ligament followed by physical therapy focused on restoring normal range of motion, quadriceps strength, and function. Subjects returned for quadriceps strength testing and gait analysis six months and two years after surgery. Acutely after injury, quadriceps strength was asymmetric between limbs, but resolved six months after surgery. Asymmetric knee angles, knee moments, and knee and hip power profiles were also observed acutely after injury and persisted six months after surgery despite subjects achieving symmetrical quadriceps strength. Two years after surgery, quadriceps strength in the involved limb continued to improve and most kinematic and kinetic asymmetries resolved. These findings suggest that adequate quadriceps strength does not immediately resolve gait asymmetries in non-copers. They also suggest that non-copers have the capacity to improve their quadriceps strength and gait symmetry long after ACL reconstruction.
