osteotomy around the knee is one of the most common corrective surgeries for lower limb deformities. The exact relationship between the effects of these surgeries on the ankle joint is unclear.This study aimed to investigate the effect of HTO on the subtalar joint in patients with genu varum.
In the case series study33 patients including 27.2% men and 72.7% womenwith an average age of 41.9, with genu varum who underwent corrective surgery of open wedge high tibial osteotomy were studied. the heel alignment angle was determined before and after surgery in 10-months follow-up based on Saltzman view in conventional radiography. The data were then compared.
Average genu varum correction angle was 11.9±1.3. Heel alignment degree was 5.9±1.3 before HTO surgery, and after the surgery,in final follow-up,it was to 3.4±1.2 valgus, this value was statisticallysignificant(p=0.04). Moreover, there was a significant statistical relationship between average correction of Varus deformity and heel alignment anglechanges (P=0.02, r=0.3).
Correcting Varus knee deformity can be effectiveon heel alignment angle in patients undergoing HTO surgery with genu varum. The angle of the subtalar valgus decreases as a result.
膝关节周围截骨术是下肢畸形最常见的矫正手术之一。这些手术对踝关节的影响的确切关系尚不清楚。本研究旨在调查高位胫骨截骨术（HTO）对膝内翻患者距下关节的影响。
在该病例系列研究中，对33例患者进行了研究，其中男性占27.2%，女性占72.7%，平均年龄41.9岁，均为接受开放性楔形高位胫骨截骨矫正手术的膝内翻患者。在术后10个月的随访中，根据传统X线摄影中的Saltzman位确定手术前后的足跟对线角度。然后对数据进行比较。
平均膝内翻矫正角度为11.9±1.3。HTO手术前足跟对线角度为5.9±1.3，术后最终随访时变为外翻3.4±1.2，该值具有统计学意义（p = 0.04）。此外，内翻畸形的平均矫正与足跟对线角度变化之间存在显著的统计学关系（P = 0.02，r = 0.3）。
对于接受HTO手术的膝内翻患者，矫正膝内翻畸形可有效改善足跟对线角度。结果导致距下外翻角度减小。
