To determine possible differences in single-hop kinematics and kinetics in females with anterior cruciate ligament reconstruction compared to healthy controls. A second purpose was to make comparisons between the healthy and reconstructed limbs.
Subjects were grouped based on surgical status (33 ACLR patients and 31 healthy controls). 3D motion capture synchronized with force plates was used to capture the landing phase of three successful trials of single hop for distance during a single data collection session. Peak values during the loading phase were analysed. Subjects additionally completed three successful trials of the triple hop for distance Tegner activity scale and International Knee Document Committee 2000 (IKDC).
Controls demonstrated greater peak knee flexion and greater internal knee extension moment and hip extension moment than ACLR subjects. Within the ACLR group, the healthy limb exhibited greater peak knee flexion, hip flexion, hip extension moment, single hop and triple hops for distance and normalized quadriceps strength.
Patients who undergo anterior cruciate ligament reconstruction land in a more extended posture when compared to healthy controls and compared to their healthy limb.

确定与健康对照组相比，前交叉韧带重建女性单跳运动学和动力学的可能差异。第二个目的是比较健康肢体和重建肢体。
根据手术状态对受试者进行分组（33例前交叉韧带重建患者和31例健康对照）。在单次数据收集期间，使用与测力台同步的三维运动捕捉技术，捕捉三次成功的单跳远距离试验的着地阶段。分析加载阶段的峰值。受试者还完成了三次成功的远距离三级跳试验、Tegner活动量表和国际膝关节文献委员会2000版（IKDC）。
与前交叉韧带重建受试者相比，对照组表现出更大的膝关节屈曲峰值、更大的膝关节内翻伸展力矩和髋关节伸展力矩。在前交叉韧带重建组中，健康肢体表现出更大的膝关节屈曲峰值、髋关节屈曲、髋关节伸展力矩、单跳和三级跳远距离以及标准化股四头肌力量。
与健康对照组及其健康肢体相比，接受前交叉韧带重建的患者着地时姿势更伸展。
