Knee pain ‘common’ among women over 50
Last updated 20 December 2011
A new study has highlighted the widespread nature of knee pain among women over the age of 50.
Scientists at the University of Oxford studied more than 1,000 women, aged 44 to 57 years, over a 12-year period in order to assess their experiences of knee pain – a condition that costs the UK £3.2 billion per year in lost productivity.
They found that 63 per cent of the women reported knee pain during the study period, with a high body mass index (BMI), history of previous knee injury and radiographic osteoarthritis acting as predictors for persistent pain.
Lead author Dr Nigel Arden, professor of rheumatology at the University of Oxford, said: ‘Our study is the first community-based investigation of knee pain patterns using multiple assessment points over a 12-year period.
‘Validation of our findings through reproduction in other patient groups is needed to advance knowledge of knee pain predictors that will ultimately enhance prevention and treatment strategies for those with osteoarthritis.’
The findings are published in the journal Arthritis & Rheumatism and show why knee replacement surgery is so common in the UK, with more than 70,000 such operations now performed each year in England and Wales alone.
