Knee replacement surgery is designed to help patients gain mobility and resume normal activities, including regular exercise. During the two years following knee surgery, how much weight do patients lose or gain?
1. Two-thirds of the patients lose 14 pounds.
2. Two-thirds of the patients neither lose nor gain weight.
3. Two-thirds of the patients gain 14 pounds.
The answer is number 3. Researchers at the University of Delaware found that the majority of patients continued their sedentary lifestyle and gained weight despite their restored mobility through knee replacement surgery. At the end of two years, the average weight gain was 14 pounds.
