摘要: [摘要]〓
〖HTH〗目的〖HTSS〗〖KG*2〗根据股骨及胫骨的形态学改变对膝内翻进行影像学分型并探讨其临床价值。
〖HTH〗方法〖HTSS〗〖KG*2〗回顾性分析1 422侧不同程度膝内翻患者下肢全长拼接正位X线片,测量相关力线和角度,并根据股骨机械轴远端内侧角(mechanical medial distal femoral angle,mMDFA)、胫骨近端内侧角(medial proximal tibial angle,MPTA)和关节线交角(joint line convergence angle,JLCA)对其进行影像学分型。比较各分型在不同性别的分布情况。
〖HTH〗结果〖HTSS〗〖KG*2〗膝内翻可分为4种类型,Ⅰ型为72.4%(1 029/1 422),Ⅱ型为1.0%(15/1 422),Ⅲ型为23.6%(335/1 422),Ⅳ型为3.0%(43/1 422)。男性和女性在影像学构成上差异无统计学意义。
〖HTH〗结论〖HTSS〗〖KG*2〗本研究将股骨的形态学改变纳入其中,以全面地反映膝内翻中整个下肢的形变情况,可为保膝治疗和全膝关节置换术提供理论依据。

Abstract: [Abstract] Objective〖HTSS〗〓To investigate the feasibility of genu varum and its clinical significance based on morphological changes of femur and tibia.
〖HTH〗〖WTHZ〗Methods〖HTSS〗〓Radiographic images of 1 422 knees of varus were collected and analyzed. The alignments were drawn and multiple parameters of lower extremities were measured. The images were classed into four types on the basis of mechanical medial distal femoral angle(mMDFA), medial proximal tibial angle(MPTA) and joint line convergence angle(JLCA). The different between the distributions of different genders was compared.
〖HTH〗〖WTHZ〗Results〖HTSS〗〓Knee varus can be divided into four types with 72.36%(1 029/1 422) of type Ⅰ, 1.05%(15/1 422) of typeⅡ, 23.56%(335/1 422) of type Ⅲ and 3.02%(43/1422) of type Ⅳ. There is no significant difference between men and women. 
〖HTH〗〖WTHZ〗Conclusion〖HTSS〗〓he typing method could fully reflect the morphological changes of the entire lowerlimb for the change of femur, and could provide a theoretical basis for the kneesalvage treatment or total knee arthroplasty.
