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.
