Airport metal detectors are quite sensitive to metals, this includes metal implants that may have been placed inside your body. Belt buckles, key chains, and steel-toed shoes may set off these sensitive metal detectors. Many commonly used orthopedic implants may also set off the metal detectors.
Total shoulder, hip, and knee replacement implants are composed of cobalt-chromium alloys or titanium and are most likely to be detected. Meanwhile, stainless-steel plates, screws, intramedullary nails, wires, and screws are the least likely implants to be detected.
Metal detectors create a magnetic field by using a brief pulse of electrical current. The magnetic field will be reflected back to the machine if there are any metal objects present, such as a watch or a belt buckle. The return signal is detected by the machine and a beeping noise is produced to alert the TSA agent.
“Millimeter wave imaging technology does not detect items inside a passenger's body or penetrate the skin,” Langston says. That said, Malvini Redden says body scanners would also not pick up anything else stashed inside a body cavity, such as drugs or hazardous liquids.
We suggest you wait 10–14 days before traveling if you have several dental implants or a more complicated procedure. It just means that there are potential problems that can come up and cause disruption, not that you cannot fly.
Roughly 90% of all implants from total knee or total hip arthroplasty will most definitely set off the security alarms when passing through an airport security scanning system. Even if your particular implant only contains small traces of metal, it will more than likely sound the alarm.
Baggy clothing can include low-hanging pants, flowy skirts, heavy sweaters or sweatshirts, and loose dresses – things that would allow malicious travelers to hide prohibited items. Airport security may need to do a pat-down inspection if your clothes are too loose and they suspect you may be hiding prohibited items.
Airport body searches, or “pat downs” involve being physically pat down by a security officer to confirm that you aren't carrying prohibited items under your clothing. Airport pat downs happen for two reasons: by random chance or because something about your clothing, appearance, or luggage seems suspicious.
In most cases, when the detector is triggered, you will be asked to go for a secondary screening which could be the use of a handheld detector or a physical pat-down. In most instances, it would not cause any major delay, however, in situations where there is an increased security threat, you could be inconvenienced.
With a knee replacement, you need to prepare to go through security. After all, your knee can set off the medical detectors. If you're planning on flying, ask your doctor to provide you with a letter that talks about your surgery. It's also possible for airport security to ask to see your surgery scar.
