Abstract

OBJECTIVE

The aim of this study was to estimate the prevalence of frequent knee pain in radiographic, symptomatic and clinically defined knee OA in middle-aged and elderly patients and the proportion that seeks medical care.

METHODS

In 2007 a random sample of 10 000 56- to 84-year-old residents of Malmö, Sweden, were questioned about knee pain. We classified subjects reporting knee pain with a duration of at least 4 weeks as having frequent knee pain. A random sample of 1300 individuals with frequent knee pain and 650 without were invited for assessment by the ACR clinical knee OA criteria and for bilateral weight-bearing knee radiography. We considered a Kellgren-Lawrence grade ≥2 as radiographic knee OA and that in combination with frequent knee pain as symptomatic knee OA. By linkage with the Skåne Healthcare Register, we determined the proportion of subjects that had consulted for knee OA or pain.

RESULTS

The 10 000 subjects had a mean age of 70 years (s.d. 7.6), a mean BMI of 27.1 kg/m(2) and 62% were women. The prevalence of frequent knee pain was 25.1% (95% CI 24.1, 26.1), higher in women and similar across age groups. The prevalence of radiographic knee OA was 25.4% while 15.4% had either symptomatic or clinically defined knee OA. Of these, 68.9% consulted a physician for knee OA or pain during 2004-11.

CONCLUSION

Fifteen per cent of middle-aged or elderly individuals have knee OA and symptoms. About one in three of those do not consult a physician. Inefficient care of OA and self-coping may be an explanation.

摘要

目的

本研究旨在评估中老年患者中，影像学诊断、有症状及临床诊断的膝关节骨关节炎（OA）患者频繁膝关节疼痛的患病率，以及寻求医疗护理的比例。

方法

2007年，对瑞典马尔默10000名年龄在56至84岁的居民进行随机抽样，询问其膝关节疼痛情况。我们将报告膝关节疼痛持续至少4周的受试者归类为有频繁膝关节疼痛。随机抽取1300名有频繁膝关节疼痛的个体和650名无频繁膝关节疼痛的个体，依据美国风湿病学会（ACR）临床膝关节OA标准进行评估，并进行双侧负重膝关节X线摄影。我们将Kellgren-Lawrence分级≥2视为影像学膝关节OA，将其与频繁膝关节疼痛相结合视为有症状的膝关节OA。通过与斯科讷医疗登记处的关联，我们确定了因膝关节OA或疼痛而咨询过医生的受试者比例。

结果

这10000名受试者的平均年龄为70岁（标准差7.6），平均体重指数（BMI）为27.1kg/m²，62%为女性。频繁膝关节疼痛的患病率为25.1%（95%置信区间24.1, 26.1），女性患病率更高，且各年龄组相似。影像学膝关节OA的患病率为25.4%，而有症状或临床诊断的膝关节OA患病率为15.4%。在这些患者中，68.9%在2004 - 2011年期间因膝关节OA或疼痛咨询过医生。
