背景：本研究的目的是回顾性研究磁共振成像（MRI）三维（3D）分析系统计算的平均年龄软骨厚度是否与国际软骨修复协会（ICRS）在各分区域的分级相关，作为关节镜评估的代表性评分。方法：选取102例膝关节内侧骨性关节炎行半月板修复或胫骨高位截骨术的患者为研究对象。软骨病变在关节镜下根据每个亚区域的ICRS分级进行量化。采用透视法比较关节镜评估的亚区与MRI评估的亚区。每个子区域的平均软骨厚度也使用我们的3D分析系统从MRI数据自动计算。采用Spearman秩相关系数评价ICRS分级与股骨内侧和胫骨内侧18个亚区平均软骨厚度之间的关系。结果：透视检查显示股骨内侧区域后亚区与关节镜和MRI的位置不匹配；因此，这三个分区域被排除在外。在股内侧区，ICRS分级与五个亚区软骨厚度的相关性中等，与一个亚区相关性较弱。在胫骨内侧区域，ICRS分级与软骨厚度在四个亚区有中等相关性，在一个亚区有弱相关性，但在其他四个亚区没有相关性。结论：MRI 3D分析确定的平均软骨厚度与关节镜下股骨内侧和胫骨区15个亚区中11个的分级相关。(c) 2023作者。这是一篇基于CC by-nc-nd许可（http://creativecommons.org/licenses/by-nc-nd/4.0/）的开放获取文章。
Background: The purpose of this study was to retrospectively investigate whether the aver-age cartilage thickness calculated by magnetic resonance imaging (MRI) three-dimensional (3D) analysis system was correlated with the International Cartilage Repair Society (ICRS) grade at each subregion, as a representative scoring for arthroscopic evaluation.Methods: The subjects were 102 patients who underwent arthroscopy for meniscus repair or high tibial osteotomy for medial osteoarthritis of the knee. Cartilage lesions were arthro-scopically quantified according to the ICRS grade at each subregion. Fluoroscopy was used to compare the subregions on arthroscopic evaluation with subregions on MRI. The average cartilage thickness at each subregion was also automatically calculated from MRI data using our 3D analysis system. The association between ICRS grade and the average carti-lage thickness at 18 subregions in the medial femoral and medial tibial regions was eval-uated using Spearman's rank correlation coefficient.Results: Examination of the fluoroscopic images revealed that the posterior subregions in the medial femoral region did not match the position between arthroscopy and MRI; there-fore, those three subregions were excluded. In the medial femoral region, the ICRS grade correlated moderately with cartilage thickness at five subregions and weakly at one subre-gion. In the medial tibial region, the ICRS grade correlated moderately with cartilage thick-ness at four subregions and weakly at one subregion, but it did not correlate at the other four subregions.Conclusion: The average cartilage thickness determined by MRI 3D analysis correlated with arthroscopic grade at 11 of 15 subregions in the medial femoral and tibial regions.(c) 2023 The Author(s).
