To compare patients with knee osteoarthritis (OA) who have and do not have back pain, and evaluate the prevalence, characteristics, and consequences of back pain among knee OA patients.
During a 3-year period, consecutive patients attending an outpatient rheumatology clinic were evaluated for the presence of back pain, and 368 were found to have OA of the knee. Clinical status was evaluated by the Clinical Health Assessment Questionnaire, radiographs, and joint examinations.
Back pain was present in 54.6% of patients with OA of the knee. Almost every clinical status measure was worse among those reporting back pain, including Health Assessment Questionnaire (HAQ) disability, pain, global severity, fatigue, and psychological status. Back pain was more common in women and the obese, but was not associated with age, marital status, formal education, smoking history, or knee radiographic scores. In multivariate analyses the strongest correlates of back pain in knee OA patients were anxiety, night pain, HAQ disability, and global severity.
Back pain is prevalent among OA clinic patients, more common than in rheumatoid arthritis or population studies, is linked to body mass index, and is associated with clinically significant increases in pain and other measures of clinical distress.
比较患有和未患有背痛的膝骨关节炎（OA）患者，评估膝OA患者中背痛的患病率、特征及后果。
在3年期间，对连续就诊于门诊风湿病诊所的患者进行背痛评估，发现368例患有膝OA。通过临床健康评估问卷、X线片及关节检查评估临床状况。
膝OA患者中54.6%存在背痛。几乎每项临床状况指标在报告有背痛的患者中都更差，包括健康评估问卷（HAQ）残疾程度、疼痛、整体严重程度、疲劳及心理状况。背痛在女性和肥胖者中更常见，但与年龄、婚姻状况、正规教育程度、吸烟史或膝部X线评分无关。在多变量分析中，膝OA患者背痛的最强相关因素是焦虑、夜间疼痛、HAQ残疾程度及整体严重程度。
背痛在OA门诊患者中普遍存在，比类风湿关节炎或人群研究中更常见，与体重指数有关，且与疼痛及其他临床不适指标的显著增加相关。
