外膝内收力矩可以通过鞋类干预来减少，但体内内侧关节负荷的确切变化仍然未知。使用内固定膝关节置换术来评估单个患者使用可变刚度干预鞋行走时体内内侧关节负荷的变化。我们假设，在使用负荷改变可变刚度鞋干预的步行过程中：（1）与受试者的个人鞋相比，第一峰值膝关节内收力矩将降低;（2）与个人鞋相比，第一峰值体内内侧接触力将降低;（3）膝关节内收力矩的降低将与内侧接触力的降低相关。手术工具包括运动捕捉系统、测力板和膝关节假体。与个人鞋相比，干预鞋降低了第一峰值膝关节内收力矩（13.3%，p=0.011）和内侧间室关节接触力（22%; p=0.008）。第一峰值膝关节内收力矩的变化与第一峰值内侧接触力的变化显著相关（R2=0.67，p=0.007）。因此，对于具有全膝关节假体的单个受试者，可变刚度鞋减少了关节的受影响间室上的负荷。膝关节外收力矩的减少表明该干预的体内内侧压缩力减少。
External knee adduction moment can be reduced using footwear interventions, but the exact changes in in vivo medial joint loading remain unknown. An instrumented knee replacement was used to assess changes in in vivo medial joint loading in a single patient walking with a variable-stiffness intervention shoe. We hypothesized that during walking with a load modifying variable-stiffness shoe intervention: (1) the first peak knee adduction moment will be reduced compared to a subject's personal shoes; (2) the first peak in vivo medial contact force will be reduced compared to personal shoes; and (3) the reduction in knee adduction moment will be correlated with the reduction in medial contact force. The instrumentation included a motion capture system, force plate, and the instrumented knee prosthesis. The intervention shoe reduced the first peak knee adduction moment (13.3%, p=0.011) and medial compartment joint contact force (22%; p=0.008) compared to the personal shoe. The change in first peak knee adduction moment was significantly correlated with the change in first peak medial contact force (R2=0.67, p=0.007). Thus, for a single subject with a total knee prosthesis the variable-stiffness shoe reduces loading on the affected compartment of the joint. The reductions in the external knee adduction moment are indicative of reductions in in vivo medial compressive force with this intervention.
