Abstract

Objective: To compare radiographic measurements of lateral tibial slope (LTS), medial TS (MTS), and coronal TS (CTS) in MRI-defined intact, injured, and mucoid-degenerated native ACL knees and determine inter-reader reliability.

Materials and methods: Patient records from 2 years at tertiary care hospitals were reviewed for individuals aged 18-100 undergoing 3-Tesla knee MRI and radiographs. Two randomly selected cohorts, control, and pathologic ACLs on MRI with 86 patients each, were age, gender, and BMI-matched. A fellowship-trained musculoskeletal radiologist reevaluated curated images, characterizing ACL status. Two trained medical students independently collected clinical data and measured slopes on blinded radiographs. ICC, Cohen's kappa, and case-control matching were performed using SPSS statistical package, with ICC and ANOVA used for comparisons.

Results: Among 172 patients with 172 MRIs and radiographs, there were 86 controls and 86 ACL lesions. There were 108/172 (62.79%) males and 64/172 (37.21%) females. ICCs were 0.966 for MTS, 0.975 for LTS, and 0.978 for CTS. Mucoid degeneration patients had a higher BMI and were older than control (p < .05) or completely torn (p < .001) ACL patients. There was no difference in TS between normal and pathologic ACLs; however, LTS-MTS differences were larger with partial tears (2.5 ± 4.9) than normal ACLs by 4.5° (± 1.2, p < .001), complete tears by 4.5° (± 1.3, p < .001), and mucoid degeneration by 4.9° (± 1.5, p = .001).

Conclusion: Various TS measurements are reliable. LTS-MTS differences are associated with different ACL lesions compared to normal ACLs.

胫骨坡度改变与前十字韧带（ACL）损伤和粘液变性的关系。

目的比较 MRI 定义的完好、损伤和粘液变性的原发性前交叉韧带膝关节的胫骨外侧斜度 (LTS)、内侧 TS (MTS) 和冠状 TS (CTS) 的影像学测量值，并确定读片者之间的可靠性：对三甲医院两年来接受 3-Tesla 膝关节 MRI 和 X 光片检查的 18-100 岁患者的病历进行回顾。随机选取了两个组群，即对照组和核磁共振检查出病态前交叉韧带的组群，每个组群有 86 名患者，他们的年龄、性别和体重指数均与对照组相匹配。一名受过研究员培训的肌肉骨骼放射科医生重新评估了策划的图像，确定了前交叉韧带的状态。两名训练有素的医科学生独立收集临床数据，并在盲法X光片上测量斜率。使用 SPSS 统计软件包进行 ICC、Cohen's kappa 和病例对照匹配，并使用 ICC 和方差分析进行比较：结果：在 172 位接受过 172 次核磁共振成像检查和 X 光片检查的患者中，有 86 位对照组患者和 86 位前交叉韧带病变患者。男性为 108/172（62.79%），女性为 64/172（37.21%）。MTS的ICC值为0.966，LTS的ICC值为0.975，CTS的ICC值为0.978。类粘液变性患者的体重指数（BMI）比对照组高，年龄比对照组大（p 结论：各种 TS 测量结果都是可靠的：各种 TS 测量值都是可靠的。与正常前交叉韧带相比，LTS-MTS差异与不同的前交叉韧带病变有关。

期刊介绍： Skeletal Radiology provides a forum for the dissemination of current knowledge and information dealing with disorders of the musculoskeletal system including the spine. While emphasizing the radiological aspects of the many varied skeletal abnormalities, the journal also adopts an interdisciplinary approach, reflecting the membership of the International Skeletal Society. Thus, the anatomical, pathological, physiological, clinical, metabolic and epidemiological aspects of the many entities affecting the skeleton receive appropriate consideration. This is the Journal of the International Skeletal Society and the Official Journal of the Society of Skeletal Radiology and the Australasian Musculoskelelal Imaging Group.
