Rising levels of obesity and desk jobs are to blame for the phenomenon of office knee - painful knee joints, say surgeons and physiotherapists.
More than a quarter of UK workers are suffering from knee pain, a new survey by healthcare provider Nuffield Health revealed has revealed
It found that people over the age of 55 suffer the most, with one in ten questioned claiming they are in constant pain.
And almost a quarter of 1,600 workers aged 16 to 65 surveyed said they have been living with pain for up to two years.
"I have seen a huge surge in the number of people with knee pain and it is down to the sedentary lifestyle people are leading now. It is very much people with desk based jobs, and some of them have been working for ten to 20 years in these roles," the Daily Mail quoted her as saying.
"I have been a physiotherapist for the past 25 years and in that time we have had the advent of the internet, which has been very much a factor," she stated.
And consultant orthopaedic surgeon Ronan Banim said that surgeons are seeing knees that are 'literally being crushed' by excess weight, which could increase the long-term risk of osteoarthritis.
He warned that if levels of obesity continue to rise the number of people needing knee replacements is likely go through the roof.
According to him, weight control, regular, careful, exercise and healthy eating could help people in avoiding the need for future surgery.
