X线片是诊断膝关节骨关节炎（OA）的最广泛的成像工具。我们的目的是确定内侧半月板挤压（MME）或软骨厚度这两个因素中的哪一个对伸展前后位视图（伸展视图）和45°屈曲后前位视图（Rosenberg视图）之间内侧间室的最小关节间隙宽度（mJSW）的差异影响更大。受试者为神奈川膝关节研究中的546名参与者（超过50名女性和50名男性，年龄分别为30、40、50、60和70岁）。从伸展位和Rosenberg位测量内侧间室的mJSW，“mJSW差异”定义为从伸展位中的mJSW减去Rosenberg位中的mJSW。软骨区域是从MRI数据中自动提取的，并在三维空间中构建。将股胫关节软骨内侧区分为18个亚区，测定各亚区的软骨厚度。MME也从MRI数据测量。4个亚区的mJSW差异与软骨厚度显著相关，相关系数绝对值最高为0.248。mJSW差异和MME也显著相关，相关系数（0.547）显著高于mJSW差异和软骨厚度。MME对伸展位和Rosenberg位内侧间室mJSW之间差异的影响大于软骨厚度。·膝关节内侧间室伸展位和屈曲位X线片宽度的差异受内侧半月板挤压的影响大于软骨厚度。
Radiographs are the most widespread imaging tool for diagnosing osteoarthritis (OA) of the knee. Our purpose was to determine which of the two factors, medial meniscus extrusion (MME) or cartilage thickness, had a greater effect on the difference in the minimum joint space width (mJSW) at the medial compartment between the extension anteroposterior view (extension view) and the 45° flexion posteroanterior view (Rosenberg view). The subjects were 546 participants (more than 50 females and 50 males in their 30 s, 40 s, 50 s, 60 s, and 70 s) in the Kanagawa Knee Study. The mJSW at the medial compartment was measured from both the extension and the Rosenberg views, and the “mJSW difference” was defined as the mJSW in the Rosenberg view subtracted from the mJSW in the extension view. The cartilage region was automatically extracted from MRI data and constructed in three dimensions. The medial region of the femorotibial joint cartilage was divided into 18 subregions, and the cartilage thickness in each subregion was determined. The MME was also measured from MRI data. The mJSW difference and cartilage thickness were significantly correlated at 4 subregions, with 0.248 as the highest absolute value of the correlation coefficient. The mJSW difference and MME were also significantly correlated, with a significantly higher correlation coefficient (0.547) than for the mJSW difference and cartilage thickness. The MME had a greater effect than cartilage thickness on the difference between the mJSW at the medial compartment in the extension view and in the Rosenberg view. • The difference in the width at the medial compartment of the knee between the extension and the flexion radiographic views was more affected by medial meniscus extrusion than by cartilage thickness.
