New Knees Please!
Each year in the United States, over 600,000 knee replacement surgeries are performed. Younger patients who are obese may experience the same amount of (or more) pain and functional disability as older patients. Over half of knee replacement patients under age 65 were considered technically obese compared to 43% of knee replacement patients over age 65. Compared with the over 65 age group, twice as many younger knee replacement patients are in the morbidly obese category.
