Previous studies have reported the relationship between coronal alignment of the lower limbs and the rotational profile of the femur and tibia. However, the relationship between coronal alignment of the femur and tibia and their rotational profiles in patients with varus osteoarthritic knees is unclear.
One hundred women with varus osteoarthritic knees (varus OA group) and 50 women with neutrally aligned lower limbs without osteoarthritis (non-OA group) were evaluated retrospectively. The coronal alignment and rotational profile of the femur and tibia were evaluated, and the correlation between coronal alignment and rotational profile was analyzed, respectively.
The femoral anteversion, posterior condylar angle of the distal femur, and tibial torsion were significantly smaller in the varus OA group than in the non-OA group. In the varus OA group, the femoral anteversion and rotational profile of the distal femur had significantly negative correlations with the degree of femoral varus, while tibial torsion was not related to the degree of tibial varus. In the non-OA group, there was no relationship between coronal alignment and rotational profiles of the femur and tibia in both the varus OA and non-OA groups.
Femoral anteversion and the rotational profile of the distal femur were negatively correlated with the degree of femoral varus in Asian women with varus osteoarthritic knees. This study enhanced the understanding of the relationship between changes in coronal alignment of the femur and tibia and their rotational profiles in patients with varus osteoarthritic lower limbs, although this study was limited by the small sample sizes and methodological quality.
之前的研究已经报告了下肢冠状对线与股骨和胫骨旋转轮廓之间的关系。然而，在膝内翻骨关节炎患者中，股骨冠状对线与胫骨及其旋转轮廓之间的关系尚不清楚。
回顾性评估了 100 名膝内翻骨关节炎女性（内翻 OA 组）和 50 名下肢对线正常且无骨关节炎的女性（非 OA 组）。评估了股骨和胫骨的冠状对线和旋转轮廓，并分别分析了冠状对线与旋转轮廓之间的相关性。
与非 OA 组相比，内翻 OA 组的股骨前倾角、股骨远端后髁角和胫骨扭转明显更小。在内翻 OA 组中，股骨前倾角和股骨远端旋转轮廓与股骨内翻程度呈显著负相关，而胫骨扭转与胫骨内翻程度无关。在非 OA 组中，无论是内翻 OA 组还是非 OA 组，股骨和胫骨的冠状对线与旋转轮廓之间均无相关性。
在亚洲膝内翻骨关节炎女性中，股骨前倾角和股骨远端旋转轮廓与股骨内翻程度呈负相关。本研究增强了对内翻下肢骨关节炎患者股骨和胫骨冠状对线与旋转轮廓变化之间关系的理解，尽管本研究受到样本量小和方法学质量的限制。
