该研究的目的是评估非骨关节炎 (n=24) 与骨关节炎 (n=9) 受试者单侧前十字韧带重建手术 5 年后步态力学的差异。对于受影响的膝盖，骨关节炎组表现出明显较低的峰值膝关节屈曲角度（非骨关节炎=24.3 +/- 4.6度，骨关节炎=19.1 +/- 2.9度，p=0.01）和峰值膝关节屈曲力矩（非骨关节炎=5.3 +/- 1.2%体重x身高，骨关节炎=4.4 +/- 1.2%体重x高度， p=0.05）。膝内收峰值时刻的差异接近显着性，骨关节炎组的差异更大（非骨关节炎=2.4 +/- 0.8% 体重x身高，骨关节炎=2.9 +/- 0.5% 体重x身高，p=0.09）。使用肌电图通知的神经肌肉骨骼模型评估峰值内侧室关节负荷。两组受累膝关节的峰值内侧间室关节负荷没有差异（非骨关节炎=2.4 +/- 0.4 体重，骨关节炎=2.3 +/- 0.6 体重）。结果表明，具有不同峰值膝力矩的受试者可以具有相似的峰值内侧间室关节负荷大小。两组均没有肢体间不对称的证据。鉴于所涉及的膝关节存在组间差异（非骨关节炎与骨关节炎），但任一组均不存在肢体间不对称性，因此在评估膝关节步态参数时，可能有必要评估随着时间的推移如何实现对称性，并区分好与坏的肢体间对称性。 (c) 2016 年骨科研究学会。由 Wiley periodicals, Inc. 出版。J Orthop Res 35:625-633，2017 年。
The objective of the study was to evaluate differences in gait mechanics 5 years after unilateral anterior cruciate ligament reconstruction surgery, for non-osteoarthritic (n=24) versus osteoarthritic (n=9) subjects. For the involved knee, the osteoarthritic group demonstrated significantly lower peak knee flexion angles (non-osteoarthritic=24.3 +/- 4.6 degrees, osteoarthritic=19.1 +/- 2.9 degrees, p=0.01) and peak knee flexion moments (non-osteoarthritic=5.3 +/- 1.2% Body WeightxHeight, osteoarthritic=4.4 +/- 1.2% Body WeightxHeight, p=0.05). Differences in peak knee adduction moment approached significance, with a higher magnitude for the osteoarthritic group (non-osteoarthritic=2.4 +/- 0.8% Body WeightxHeight, osteoarthritic=2.9 +/- 0.5% Body WeightxHeight, p=0.09). Peak medial compartment joint load was evaluated using electromyography-informed neuromusculoskeletal modeling. Peak medial compartment joint load in the involved knee for the two groups was not different (non-osteoarthritic=2.4 +/- 0.4 Body Weight, osteoarthritic=2.3 +/- 0.6 Body Weight). The results suggest that subjects with dissimilar peak knee moments can have similar peak medial compartment joint load magnitudes. There was no evidence of inter-limb asymmetry for either group. Given the presence of inter-group differences (non-osteoarthritic vs. osteoarthritic) for the involved knee, but an absence of inter-limb asymmetry in either group, it may be necessary to evaluate how symmetry is achieved, over time, and to differentiate between good versus bad inter-limb symmetry, when evaluating knee gait parameters.
