To assess the optimal duration of daily wear for a laterally wedged insole with subtalar strapping in subjects with medial compartment osteoarthritis of the knee (knee OA).
The setting was an outpatient clinic. Eighty-one patients with knee OA were prospectively randomized according to birth date and to either 2 weeks of treatment with a lateral wedge with subtalar strapping for less than 5 h (the short group), 5-10 h (the medium group) or greater than 10 h (the long group) each day, or to treatment with a subtalar strapping band without lateral wedge (the placebo group). Standing radiographs were used to analyze the femorotibial angle for each subject, both with and without their respective orthotic device. The remission scores of Lequesne index were compared among the four groups at the conclusion.
The short (n=21), medium (n=20) and long (n=18) groups demonstrated a significant greater valgus correction of the femorotibial angle than the placebo group (n=22) (P<0.0001). The remission score was significantly improved in the medium group compared to the placebo (P=0.001) and long (P=0.001) groups.
An optimal duration of insole with subtalar strapping wear for patients with varus deformity knee OA may be between 5 and 10 h each day.
评估在患有膝关节内侧间室骨关节炎（膝骨关节炎）的受试者中，佩戴带有距下绑扎的外侧楔形鞋垫的最佳每日时长。
研究地点为门诊诊所。81例膝骨关节炎患者根据出生日期前瞻性随机分组，分别接受以下治疗：每天佩戴带有距下绑扎的外侧楔形鞋垫少于5小时（短组）、5 - 10小时（中组）或超过10小时（长组），或佩戴无外侧楔形的距下绑扎带（安慰剂组）。使用站立位X线片分析每位受试者在佩戴和不佩戴各自矫形装置时的股胫角。在研究结束时比较四组的Lequesne指数缓解评分。
短组（n = 21）、中组（n = 20）和长组（n = 18）的股胫角外翻矫正程度显著大于安慰剂组（n = 22）（P < 0.0001）。与安慰剂组（P = 0.001）和长组（P = 0.001）相比，中组的缓解评分显著改善。
对于患有膝内翻畸形骨关节炎的患者，佩戴带有距下绑扎的鞋垫的最佳时长可能为每天5至10小时。
