The authors present an atlas of individual radiographic features of osteoarthritis of the knee and evaluate the inter- and intra-reader reliability of trained readers using this atlas.
Four trained readers graded 30 standing anterior-posterior knee radiographs for eight selected features of osteoarthritis (medial and lateral osteophytes, joint space narrowing, and sclerosis; osteophytes of the tibial spines and chondrocalcinosis) as well as the Kellgren-Lawrence global scale. Inter- and intra-reader reliability were calculated using intraclass correlation coefficients.
For all features except sclerosis and osteophytes of the tibial spines, inter-reader reliability ranged from 0.63 to 0.83, whereas intra-reader reliability ranged from 0.82 to 0.95.
Using this atlas, trained readers are reliable in measuring the presence and severity of individual radiographic features of osteoarthritis of the knee. This atlas should be useful in clinical and epidemiologic studies of osteoarthritis of the knee.
作者展示了一本关于膝关节骨关节炎个体影像学特征的图谱，并使用该图谱评估了训练有素的阅片者之间以及阅片者自身的可靠性。
四名训练有素的阅片者对30张站立位膝关节前后位X线片的八个选定骨关节炎特征（内侧和外侧骨赘、关节间隙变窄和硬化；胫骨棘骨赘和软骨钙质沉着症）以及Kellgren-Lawrence整体分级进行评分。使用组内相关系数计算阅片者之间以及阅片者自身的可靠性。
除胫骨棘硬化和骨赘外，所有特征的阅片者间可靠性范围为0.63至0.83，而阅片者自身可靠性范围为0.82至0.95。
使用该图谱，训练有素的阅片者在测量膝关节骨关节炎个体影像学特征的存在和严重程度方面是可靠的。该图谱应有助于膝关节骨关节炎的临床和流行病学研究。
