Adults who gain a lot of weight are at an increased risk of having a repair surgery for their arthritic knees.
Researchers from the Finnish Institute of Occupational Health found that people who are slim at the age of 20 years but are overweight for most of the next 30 years are three times more likely to need a knee surgery than those who stayed at a normal weight, a private TV channel reported. People who gained weight by 30 years of age and did not lose it were also posed to a three times risk of developing knee problems.
However, people who gained weight by the age of 20 were twice as likely to require knee surgery as compared to normal weight people. The findings suggest that being constantly overweight carry lesser risk of having knee problems than adding a lot of pounds in adulthood.
