单侧下肢截肢的人在其完整肢体中有发生骨关节炎的风险。在没有截肢的人中，膝关节骨关节炎疾病的严重程度与额状面膝关节力矩升高有关。因此，本研究的目的是检查单侧经胫骨截肢患者的膝关节和髋关节额状面力矩。我们假设，膝关节和髋关节内外展力矩是更大的完整的肢体相比，假体侧。对10名单侧经胫骨截肢者在行走过程中进行双侧三维步态力学测量，以计算下肢关节力矩。完整肢体膝关节和髋关节峰值内展力矩分别比假体侧大46%和39%。完整侧膝关节和髋关节峰值内外展力矩分别比正常值高17%和6%。较大的力矩表明关节载荷在完整侧上具有较高的幅度，这可能倾向于过早的关节退变，特别是膝关节骨关节炎。(c)2005 Elsevier B.V.保留所有权利。
Persons with unilateral, lower-extremity amputation are at risk of developing osteoarthritis in their intact limb. Among persons without amputation, knee osteoarthritis disease severity has been linked to elevated frontal plane knee moments. Therefore, the purpose of this study was to examine knee and hip frontal plane moments in persons with unilateral, trans-tibial amputation. We hypothesized that knee and hip internal abduction moments are greater in the intact limb compared to the prosthetic side. Three-dimensional gait mechanics were measured bilaterally from 10 persons with unilateral, trans-tibial amputation during walking, to calculate lower-extremity joint moments. The intact limb knee and hip peak internal abduction moments were 46% and 39% greater, respectively, than on the prosthetic side. The intact side knee and hip peak internal abduction moments were 17% and 6% greater, respectively, than normal. Larger moments suggest joint loading is of higher magnitude on the intact side, which may be predisposed to premature joint degeneration, particularly knee osteoarthritis. (c) 2005 Elsevier B.V.
