Abstract Summary
Individuals with lower limb amputation often develop overuse injuries and osteoarthritis in the intact knee. Unfortunately, how prosthetic foot stiffness and load carriage technique influences intact knee joint loading during amputee gait is not well understood. This study found that during unloaded walking, using a standard of care prosthetic foot resulted in the lowest intact knee joint loading. However, while carrying both an anterior and posterior load, the standard of care foot produced higher knee joint loading compared to stiffer feet such as those with a heel-stiffening wedge.
