通过体格检查和步态分析，研究了长期使用假肢的非截肢腿负荷增加导致骨关节炎风险增加的假设。 根据一组有经验的经胫骨截肢者和一组相似的非截肢者对照组的临床结果，截肢者组在其非截肢腿的膝关节骨关节炎的发生率显著更高（p < 0.05）。 截肢者组的膝关节反作用力、关节冲量、净关节力矩和净关节功率始终较大。 截肢者在步态双支撑阶段的垂直冲量和净关节功率显著较高（p < 0.05）。 这些结果支持了这一假设，即老年人，经胫骨截肢者有更高的风险发展为骨关节炎和经验更大的力量，在膝盖的非截肢肢体比人没有下肢截肢。
The hypothesis that an increased load on the nonamputated leg of long-term prosthetic users leads to an increased risk of developing osteoarthritis was investigated using physical examinations and gait analysis. Based on the clinical results from an elderly group of experienced trans-tibial amputees and a similar control group of nonamputees, the amputee group experienced a significantly greater incidence of osteoarthritis (p < 0.05) in the knee of their nonamputated leg. The amputee group had consistently larger knee joint reaction forces, joint impulses, net joint moments, and net joint powers. Significantly higher results (p < 0.05) were found for amputee vertical impulse and net joint power during the double support phase of gait. These results support the hypothesis that elderly, trans-tibial amputees have a higher risk of developing osteoarthritis and experience larger forces at the knee of their nonamputated limb than people without lower extremity amputations.
