Background. The benefit of physical activity for the prevention and treatment of cardiovascular disease (CVD) has been well documented. The aim of the present study was to determine the level of awareness among general practitioners (GPs) of knee and hip problems in patients with CVD or CVD risk. Design. Cross-sectional questionnaire survey. Setting and Subjects. Thirty-five Austrian GPs and 1,118 patients were included. The GPs completed an extraction form about the presence or absence of documented evidence of problems related to the knee and/or hip joint within the patient medical data. Patients, in turn, were asked to complete a questionnaire that included the Oxford Knee/Hip Score and the cardiovascular risk-chart established by the European Society of Cardiology. Results. In 748 patients' data from medical records and questionnaires were available. 40.9% of these patients suffered from serious knee pain and 32.1% from hip pain. However, in the medical records, in only 51.3% (knee) and 48.1% (hip) of these pain-patients the problems were documented. Conclusion. Joint disorders of the knee and hip problems are considerable barriers to effective physical activity and can therefore contribute to the development of CVD. Our data showed that GP awareness of such knee/hip disorders should be improved.
