The flexion of the femoral component in the sagittal plane in unicompartmental knee arthroplasty (UKA) was analyzed radiographically in this study. Thirty medial and 30 lateral UKAs were included. The sagittal flexion angles were measured both relative to the posterior femoral cortex and midline sagittal distal femoral axis. Both of the measurement methods revealed that the femoral components were inserted in a significantly more flexed fashion in the medial UKA group. Neither preoperative nor postoperative tibial slope did have any significant effect on the sagittal flexion angle. To the best of our knowledge, this is the first study demonstrating an angular difference in the sagittal flexion of the femoral components between medial and lateral UKAs.
本研究对单髁膝关节置换术中股骨组件在矢状面的弯曲进行了放射学分析。共纳入 30 例内侧 UKA 和 30 例外侧 UKA。分别测量了相对于股骨后皮质和正中矢状远端股骨轴的矢状面弯曲角度。两种测量方法均显示，内侧 UKA 组股骨组件的插入方式明显更为弯曲。术前和术后胫骨倾斜度均对矢状面弯曲角度无显著影响。据我们所知，这是首次证明内侧和外侧 UKA 之间股骨组件矢状面弯曲角度存在差异的研究。
