A comparative analysis by applying the criteria of the original classification Ahlbäck in the anteroposterior (AP) bipedal knee in extension and anteroposterior (AP) monopodal knee in symptomatic knee arthrosis. With this analysis we intend to observe the agreement, any advantage or difference between the incidence and degree of joint involvement between the orthopedic surgeons and radiologists with the referring physician.
From January 2012 to March 2012, was a prospective study of 60 symptomatic arthrosis knees (60 patients), clinically selected group of outpatient knee and radiographic proposals submitted to the search. Of the 60 patients, 39 were female and 21 male, mean age 64 years (ranging from 50 to 84 years). Of the 60 knees studied, 37 corresponded to the right side and 23 on the left side. Statistical analysis was performed by Kappa statistics, which evaluates the interobserver agreement for qualitative data.
According to the scale of Ahlbäck, there was a significant agreement (p < 0.0001) intra-observer in the classification of knee osteoarthritis among the five evaluators. There was a significant agreement (p < 0.0001) with inter-observer referring physician in the incidence of AP monopodal and AP bipedal for the four raters.
The study found no difference between the incidence in the AP monopodal versus AP bipedal in osteoarthritis of the knee.
运用原始的阿尔贝克（Ahlbäck）分类标准，对有症状的膝关节骨关节炎患者在双足站立位膝关节伸直前后位（AP）片及单足站立位膝关节前后位（AP）片进行对比分析。通过该分析，我们旨在观察骨科医生、放射科医生与转诊医生之间在关节受累发生率及程度上的一致性、任何优势或差异。
2012年1月至2012年3月，对60例有症状的膝关节骨关节炎患者（60个膝关节）进行前瞻性研究，这些患者均为临床筛选出的门诊膝关节病例，并提交了影像学检查申请。60例患者中，女性39例，男性21例，平均年龄64岁（年龄范围50至84岁）。在研究的60个膝关节中，右侧37个，左侧23个。采用Kappa统计进行统计学分析，该统计用于评估定性数据的观察者间一致性。
根据阿尔贝克（Ahlbäck）量表分析，5名评估者在膝关节骨关节炎分类上观察者内一致性显著（p < 0.0001）。4名评估者与转诊医生在单足站立位AP片和双足站立位AP片的发生率上观察者间一致性显著（p < 0.0001）
该研究发现在膝关节骨关节炎中，单足站立位AP片与双足站立位AP片的发生率无差异。
