Fears that wearing high-heeled shoes could lead to knee arthritis are
unfounded,say researchers.
But being overweight,smoking,and having a previous knee injury does
increase the risk,the team from Oxford Brookes Universtity found.
They looked at more than 100 women aged between 50 and 70 waiting for knee
surgery, and found that choice of shoes was not a factor
The study was published in the Journal of Epidemilology and public
health.
More than 2% of the population aged over 55 suffers extreme pain as a
result of osteoarthrits of the knee.
The condition is twice as common in 65-year-old women as it is in men of
the same age.
Women's and men's knees are not biologically different, so the reserachers
wanted to find out why twice as many women as men develop osteoarthritis in the
joint.
Some researchers have speculated tha high-heeled shoes maybe to blame.
The women in the study were quizzed on details of their height and weight
when they left school, between 36 and 40 and between 51 and 55.
They were asked about injuries, their jobs, smoking and use of
contraceptive hormones.
Howere, while many of these factors were linked to an increased risk over
the years was not.
The researchers wrote:"Most of the women had been exposed to high heeled
shoes over the years-nevertheless, a consistent finding was a reduced risk of
osteoarthritis of the knee.
There was an even more pronounced link between regular dancing in
three-inch heels and a reduced risk of knee problems.
The researchers described this finding as "surprising", but said that they
would not expect a larger-scale study to overturn their findings
