外侧脚楔入治疗膝关节内侧骨关节炎的方法正在研究中。有趣的是，很少有人对长期使用的生物力学效果进行评估。因此，我们的目的是评估动态膝关节负荷（通过膝关节内收力矩进行评估）和其他次要步态参数，这些患者在基线就诊时和佩戴外侧足楔1年后佩戴内侧膝关节骨性关节炎。在干预组中，19名症状性膝内侧骨关节炎患者在0个月和12个月时佩戴他们规定的外侧楔形足矫形器，获取三维步态数据。根据降压试验的症状反应来规定楔形剂量。对照组19例患者在0个月和12个月时佩戴规定的中性矫形器。另外还记录了佩戴中性矫形器的干预组的步态。行走速度和鞋子都受到控制。进行方差分析，以检验按时间分组（使用指定矫形器的组之间）和按时间分组（干预组内）的相互作用、主要效应和简单效应。我们观察到，随着时间的推移，对照组的膝关节内收力矩和额平面运动增加，但干预组没有。此外，在干预组内，侧楔的机械有效性没有降低。在内侧膝骨关节炎患者中，外侧脚楔入对内侧膝骨关节炎相关的病理力学的影响是有利的，并持续一段时间。
The use of lateral foot wedging in the management of medial knee osteoarthritis is under scrutiny. Interestingly, there have been minimal efforts to evaluate biomechanical effectiveness with long term use. Therefore, we aimed to evaluate dynamic knee loading (assessed using the knee adduction moment) and other secondary gait parameters in patients with medial knee osteoarthritis wearing lateral foot wedging at a baseline visit and after 1 year of wear. 3-dimensional gait data were captured in an intervention group of 19 patients with symptomatic medial knee osteoarthritis wearing their prescribed laterally wedged foot orthoses at 0 and 12 months. Wedge amounts were prescribed based on symptom response to a step-down test. A control group of 19 patients wearing prescribed neutral orthoses were also captured at 0 and 12 months. The gait of the intervention group wearing neutral orthoses was additionally captured. Walking speed and shoes were controlled. Analyses of variance were conducted to examine for group-by-time (between the groups in their prescribed orthoses) and condition-by-time (within the intervention group) interactions, main effects, and simple effects. We observed increased knee adduction moments and frontal plane motion over time in the control group but not the intervention group. Further, within the intervention group, the mechanical effectiveness of the lateral wedging did not decrease. In patients with medial knee osteoarthritis, the effects of lateral foot wedging on pathomechanics associated with medial knee osteoarthritis were favorable and sustained over time.
