摘要
背景/目的:本研究旨在阐明利用超声成像评估胫骨外旋对位的可重复性、有效性和准确性,并探讨膝关节骨性关节炎(OA)患者矢状面和冠状面上内侧半月板挤压(MME)与胫股骨对位之间的关系。研究方法研究 1 包括 10 名健康参与者。通过核磁共振成像计算胫骨外旋角。在超声成像评估中,胫骨髁和股骨髁最后方至皮肤的距离差值分别被计算为内侧和外侧髁间隙。从内侧髁间隙减去外侧髁间隙,计算出内侧外侧(ML)间隙。研究 2 包括 63 名单侧 OA 患者和 16 名健康对照组。MME根据OA的严重程度、胫骨旋转程度以及是否存在胫骨后移进行比较。结果显示超声成像检查显示出较高的评分者内部和评分者之间的可靠性(0.786-0.979)。ML间隙对磁共振成像测定的胫骨外旋角有明显影响。超声成像的ML间隙与核磁共振成像的ML间隙显著相关。早期 OA 组的 MME 明显高于对照组。胫骨旋转度不同,MME也无明显差异。胫骨后移组的MME明显高于无后移组。结论超声成像可用于评估膝关节排列。MME与胫骨后移有关。
Relationship Between the Sagittal and Coronary Alignment of the Tibiofemoral Joint and the Medial Meniscus Extrusion in Knee Osteoarthritis.
Background/Objectives: This study aims to clarify the reproducibility, validity, and accuracy of tibial external-rotation alignment evaluation using ultrasound imaging and to investigate the relationship between medial meniscus extrusion (MME) and tibiofemoral alignment in both the sagittal and coronal planes in knee osteoarthritis (OA). Methods: Study 1 included 10 healthy participants. The tibial external-rotation angle was calculated using MRI. In the ultrasound imaging evaluation, the differences in the distance from the most posterior points of the tibial and femoral condyles to the skin were calculated as the medial and lateral condyle gaps, respectively. The mediolateral (ML) gap was calculated by subtracting the lateral condyle gap from the medial condyle gap. Study 2 included 63 patients with unilateral OA and 16 healthy controls. MME was compared according to the severity of OA, the degree of tibial rotation, and the presence or absence of a tibial posterior shift. Results: Ultrasound imaging examinations showed high intra- and inter-rater reliabilities (0.786-0.979). The ML gap significantly affected the tibial external-rotation angle, determined using MRI. The ML gap of ultrasound imaging was significantly correlated with the ML gap of MRI. MME was significantly higher in the Early OA group than in the Control group. There was no significant difference in MME based on the tibial rotation degree. The group with a tibial posterior shift exhibited significantly more MME than that without a posterior shift. Conclusions: Ultrasound imaging is useful for evaluating knee alignment. MME was found to be associated with the tibial posterior shift.
