There are limited studies regarding the effects of high tibial osteotomy (HTO) on other areas of lower extremity. In current study, we investigated the changes of tibiotalar joint following HTO.
A total of 39 patients with genu varum requiring HTO were enrolled in this before and after study. The genu varus, joint diversion (JDA), lateral distal tibial (LDTA) and lateral distal tibial-ground surface (LDT-GSA) angles were measured before the operation and compared with 6 months after the surgery.
Twenty threeout of39 patients (59%) were females. The genu varus angle decreased significantly (13°±1.7° versus 0.6°±1°). No significant changes were seen in JDA (=0.45) and LDTA (=0.071). LDT-GSA changed significantly (=0.011) from 8.1°±1° in varus to -0.3°±0.5° in valgus.
Although HTO did not change the JDA and LDTA, however, significant change in LDT-GSAindicates that HTO can significantly decrease the shearing forces exerted on the ankle joint.
关于高位胫骨截骨术（HTO）对下肢其他部位影响的研究有限。在本研究中，我们调查了HTO术后胫距关节的变化。
本项前后对照研究共纳入39例需要进行HTO的膝内翻患者。术前测量膝内翻、关节偏移（JDA）、胫骨远端外侧角（LDTA）和胫骨远端外侧与地面夹角（LDT-GSA），并与术后6个月进行比较。
39例患者中23例（59%）为女性。膝内翻角度显著减小（13°±1.7°对0.6°±1°）。JDA（=0.45）和LDTA（=0.071）无显著变化。LDT-GSA有显著变化（=0.011），从内翻时的8.1°±1°变为外翻时的-0.3°±0.5°。
尽管HTO未改变JDA和LDTA，但LDT-GSA的显著变化表明HTO可显著降低作用于踝关节的剪切力。
