Examination of the knee to assess the narrowing of the joint gap or joint space width (JSW) is commonly done by manually checking radiographs and measuring the JSW using a ruler.
This study aims to compare manual and automatic measurements with the diagnosis of grade I and grade II knee osteoarthritis.
In this cross-sectional study, 40 patients with the criteria for primary osteoarthritis (OA), aged 46 to 65 years old had knee OA grades of either I or II. The knee image was evaluated by a computer program and a radiologist manually viewing and measuring the JSW joint gap using a ruler.
The results showed there were no differences in the measurement of JSW medial and JSW lateral manually in grade I and grade II knee OA, at p=0.605 and p=0.344, respectively. Whereas in the automatic measurements, there was a difference between JSW medial and lateral JSW in grade I and grade II knee OA, each with p<0.001. The manual JSW measurement between medial JSW and lateral JSW in grade I and II showed that the medial and lateral knee joints have a similar distance. In the automatic, the average value of measurement lateral JSW in OA grades I and II was greater than the medial JSW.
Automatic measurements showed that both of medial and lateral JSW at grade II OA knee were narrower than the results at grade I. Automatic measurement of JSW results was more consistent than the manual measurement method.
评估膝关节间隙变窄或关节间隙宽度（JSW）通常是通过手动检查X线片并用尺子测量JSW来完成。
本研究旨在比较手动测量和自动测量在诊断I级和II级膝关节骨关节炎中的差异。
在这项横断面研究中，40例符合原发性骨关节炎（OA）标准、年龄在46至65岁之间的患者，其膝关节OA分级为I级或II级。膝关节图像由计算机程序进行评估，同时由放射科医生手动观察并用尺子测量JSW关节间隙。
结果显示，在I级和II级膝关节OA中，手动测量内侧JSW和外侧JSW时无差异，p值分别为0.605和0.344。而在自动测量中，I级和II级膝关节OA的内侧JSW和外侧JSW之间存在差异，p值均<0.001。I级和II级中内侧JSW与外侧JSW的手动JSW测量结果表明，膝关节内侧和外侧的距离相似。在自动测量中，I级和II级OA的外侧JSW测量平均值大于内侧JSW。
自动测量显示，II级OA膝关节的内侧和外侧JSW均比I级时的结果更窄。JSW结果的自动测量比手动测量方法更具一致性。
