Dr. Jesse Doty, UT Erlanger Orthopaedics, explains why running may still be good exercise for bad knees in this week’s Ask a Doctor
Q: We've heard it for years: Running is bad for your knees. But is that actually true?
A: Some people think running gradually wears away the cartilage in the knees. When you're running, you're putting a good deal of force and pressure on your knee joint, so one might assume that runners eventually develop knee pain and arthritis.
