If you think everyone you know is considering a knee replacement because of painful knees, you’re not wrong. Johns Hopkins orthopedic surgeon Stefan Coombs says knee osteoarthritis is the number one cause of adult disability nationally, and the number of folks reporting this condition continues to increase. 

Coombs: This is believed to be highly prevalent today because of the significant increase in life expectancy.
