UNASSIGNED: Between April 2021 and December 2022, 176 patients (60 males and 116 females) were investigated. Full-weight-bearing coronal whole-leg radiographs were obtained with the patella centred on the femoral condyle. Patients were divided by Kellgren-Lawrence grade (KL-0, KL-I, KL-II and KL-III) and assessed in two standing positions: legs closed and legs spread. Patients with flexion contractures or those unable to stand with full weight bearing were excluded. The mechanical distal femoral angle, medial proximal tibial angle (MPTA), femorotibial angle, joint line convergence angle, percentage weight-bearing line (%WBL) and hip-knee-ankle angle (HKAA) were measured. The Student\'s t test was used to compare the two standing positions. A p value < 0.05 indicated a statistically significant difference.
UNASSIGNED: The MPTAs of legs closed standing and legs spread standing were 84.9 ± 2.6° and 85.1 ± 2.4° in KL-0, 84.7 ± 2.0° and 84.9 ± 2.1° in KL-I and 85.0 ± 2.43° and 85.4 ± 2.4° in KL-II, respectively. There were statistically significant differences in the MPTA between the two standing positions in KL-0, KL-I and KL-II. In contrast, the %WBL and HKAA did not change regardless of the standing position. In the KL-III group, no statistical significance was observed for any of the anatomical parameters.
UNASSIGNED: Several anatomical parameters were changed between the legs closed standing and the legs spread standing positions. It was suggested that the standing position should be taken into consideration in the planning for HTO.
UNASSIGNED: Level IV, Case series with no comparison group.
■在2021年4月至2022年12月之间,对176名患者(60名男性和116名女性)进行了调查。获得了全负重冠状全腿X线照片,髌骨以股骨髁为中心。患者按Kellgren-Lawrence分级(KL-0,KL-I,KL-II和KL-III),并以两种站立姿势进行评估:双腿闭合和双腿伸展。排除屈曲挛缩或无法完全负重站立的患者。股骨远端机械角度,胫骨近端内侧角(MPTA),股胫骨角,连接线收敛角,测量负重线百分比(%WBL)和髋-膝-踝角度(HKAA)。学生t检验用于比较两个站立位置。P值<0.05表示统计学上显著的差异。
■腿部闭合站立和腿部伸展站立的MPTA在KL-0中为84.9±2.6°和85.1±2.4°,在KL-I中为84.7±2.0°和84.9±2.1°,在KL-II中为85.0±2.43°和85.4±2.4°,分别。在KL-0,KL-I和KL-II的两个站立位置之间的MPTA存在统计学上的显着差异。相比之下,无论站立位置如何,%WBL和HKAA都没有变化。在KL-III组中,任何解剖学参数均未观察到统计学意义.
■在双腿闭合站立和双腿伸展站立位置之间改变了几个解剖参数。有人建议,在规划HTO时应考虑到常设立场。
■四级,病例系列无对比组。
