目标。比较站立伸展位（SEV）（也称为站立正位位）与半屈位、后前位位（跖趾位（MTP））在繁忙的常规x线检查中评估膝关节骨关节炎关节间隙宽度（JSW）和骨赘的再现性。47名患者（24名男性）在繁忙的国民健康服务x线摄影部门同一天接受了SEV和MTP视图。在接下来的两周内，在同一部门，在选择放射技师、一天中的时间或x光机方面没有特别安排，在完全独立的程序中进行重复检查。前24例患者在SEV位有第二次视图，其余23例有第二次MTP视图。x线片由两名经验丰富的观察员独立阅读，他们用透明尺子在双膝胫股关节内侧和外侧腔室最窄处测量JSW，精确到0.5 mm。骨赘根据标准图谱分为0-2级。随机选择10张SEV片和10张MTP片，由一名观察者重新阅读。SEV片内侧室JSW平均值（95%可信区间）为3.54 mm (3.08, 3.99)， MTP片为2.80 mm (2.37, 3.23)；侧室SEV片为6.04 mm (5.71, 6.37)， MTP片为5.47 mm（5.09, 5.85）。内侧室的估计差异SEV为2.0 mm(2), MTP (P)为0.2 mm(2)
Objective. To compare the reproducibility of the standing extended view (SEV) (also known as the standing anteroposterior view) with the semiflexed, postero-anterior view [the 'metatarsophalangeal' (MTP)] view for assessing joint space width (JSW) and osteophytes in osteoarthritis of the knee when used in a busy routine X-ray department.Methods. Forty-seven patients (24 men) had both SEV and MTP views taken on the same day in a busy National Health Service radiography department. Repeat views were taken as entirely separate procedures some time over the following 2 weeks, in the same department and with no special arrangements for the selection of radiographers, time of day, or X-ray machine. The first 24 patients had second views in the SEV position whilst the remaining 23 had second MTP views. Radiographs were read independently by two experienced observers who measured JSW with a transparent ruler to the nearest 0.5 mm at the narrowest point in both medial and lateral compartments of the tibiofemoral joint in both knees. Osteophytes were graded 0-2 according to a standard atlas. Ten SEV and 10 MTP radiographs selected randomly were re-read by one observer.Results. Mean (95% confidence interval) JSW in the medial compartment measured on SEV radiographs was 3.54 mm (3.08, 3.99) and on MTP radiographs it was 2.80 mm (2.37, 3.23); in the lateral compartment it was 6.04 mm (5.71, 6.37) when measured on SEV radiographs and 5.47 mm (5.09, 5.85) on MTP radiographs. The estimated variances for the medial compartment were 2.0 mm(2) for SEV and 0.2 mm(2) for MTP (P
