To demonstrate whether or not there is a correlation between the risk factors for gonarthrosis and the radiographic classification of Ahlbäck.
We studied patients with primary gonarthrosis attended at the knee outpatient clinic of the General Hospital of Vila Penteado during their routine visit. We collected data on patient age (years), weight (kg), height (meters), body mass index (BMI = patient weight/height), personal history of hypertension or diabetes mellitus (positive or negative), sedentarism (physical activity less than three times per week, 30 minutes per session), functional demand (how many blocks walked weekly), time of onset of symptoms (in years) and laterality or bilaterality. The data were correlated with the Ahlbäck classification applied to the radiographs performed at the time of the consultation.
A sample of 108 patients was studied. We did not find an association between the Ahlbäck classification and the patient's age, smoking, sedentary lifestyle, laterality, number of blocks walked per week, diabetes mellitus, and sex; however, a positive association was observed in hypertensive patients as well as a weak correlation with height and weight of the patient and moderate correlation with BMI.
The Ahlbäck classification is unrelated to most of the risk factors for primary gonarthrosis.
证明膝关节病的危险因素与阿尔贝克（Ahlbäck）影像学分类之间是否存在相关性。
我们研究了在维拉彭特多综合医院膝关节门诊接受常规检查的原发性膝关节病患者。我们收集了患者的年龄（岁）、体重（千克）、身高（米）、体重指数（BMI = 患者体重/身高）、高血压或糖尿病个人史（阳性或阴性）、久坐不动（每周体育活动少于三次，每次30分钟）、功能需求（每周步行的街区数）、症状出现时间（年）以及单侧或双侧情况等数据。这些数据与在会诊时所拍X光片上应用的阿尔贝克分类进行了相关性分析。
研究了108例患者的样本。我们未发现阿尔贝克分类与患者的年龄、吸烟、久坐的生活方式、单侧性、每周步行的街区数、糖尿病及性别之间存在关联；然而，在高血压患者中观察到了正相关，并且与患者的身高和体重存在弱相关性，与BMI存在中度相关性。
阿尔贝克分类与原发性膝关节病的大多数危险因素无关。
