Percentage of people aged over 45 with severe knee osteoarthritis (severe) (6616) Metric type
- Help text
- This is the percentage of people aged over 45 with severe osteoarthritis of the knee. Osteoarthritis (OA) is a major public health issue due to its high prevalence, costs, pain and disability. Common OA symptoms are soreness, pain, stiffness, swelling, tenderness, aching and/or discomfort. OA can affect any joint, but most commonly affects the knee, hip and hand. Many factors can increase your risk of OA, and it's often a combination of these that lead to its development. The main risk factors for osteoarthritis include age, gender, obesity, bone density, joint injury or disease, occupation, joint abnormalities, and genetic factors. Knowledge of risk factors for onset of OA is helpful as many of them are modifiable, such as obesity and physical inactivity. Severe osteoarthritis includes cases that would require special attention, and additional resources, from healthcare providers and commissioners. This definition was developed using two survey questions: severity of pain most of the time and difficulty walking a mile unaided. Respondents were deemed to have severe osteoarthritis if their answers included any one of the following statements: They have severe pain most of the time (as opposed to mild or moderate); They're unable to walk a mile unaided (as opposed to no, some or much difficulty); They've previously undergone hip or knee replacement due to arthritis. There are currently no routinely collected data on the prevalence of this condition so the data provided here are small area modelled estimates. The estimates are based on a statistical model commissioned by Arthritis Research UK from Imperial College London using the English Longitudinal Study of Ageing (ELSA) Wave 1 (2000/01) - Wave 5 (2010/11). After analysis, survey information contained in ELSA was combined with known local data about the different risk factors to produce the model and applied to ONS Mid-Year Population Estimates for 2012. The English Longitudinal Study of Ageing (ELSA) is a large multicentre and multidisciplinary study of people aged 50 and over and their younger partners, living in private households in England. It was chosen as the basis for the prevalence models because the sample used in ELSA is designed to be nationally representative and osteoarthritis is rare under 50 years of age.
