Airport Metal Detectors and Your New Knee

Medically Reviewed

Got an artificial knee? Expect any metal in it to set off airport metal detectors. To avoid that, here's what to do.

First, inform a Transportation Security Administration officer about your knee before you’re screened. (If you want to be discreet, you can download a TSA Notification Card to show the officer, although a card isn’t required.)

The TSA won’t accept a note from your doctor or a medical card, so expect to be screened by either advanced imaging technology or a pat-down.

Consider wearing loose clothing, so if you must undergo a pat-down, you can easily show the TSA officer your scar.
