If you’ve had orthopedic surgery—such as a knee replacement, hip replacement, fracture repair, or metal hardware placement—you may wonder how your implant will affect airport security screening. At Direct Orthopedic Care, our orthopedic specialists are often asked whether metal implants trigger airport metal detectors and what patients should expect when traveling after surgery.
The short answer: yes, orthopedic implants can set off airport security systems, but knowing what to expect can make the process smoother and far less stressful.
Why Orthopedic Implants Trigger Metal Detectors
Airport metal detectors are designed to detect a wide range of metals, including those commonly used in orthopedic implants. The most frequently implanted orthopedic materials include:
-
Stainless steel
-
Cobalt chrome
-
Titanium
As airport security technology has become more advanced, screening equipment is more sensitive than ever. While some newer systems can better differentiate between metal alloys, many travelers with orthopedic implants still experience additional screening.
Types of Airport Security Screening Equipment
Airports use several types of screening technology, and your experience may vary depending on the equipment in use:
-
Walk-through metal detectors: These do not use radiation but will often alarm when metal implants are present.
-
Millimeter-wave scanners: Use non-ionizing radiofrequency waves and are commonly used for full-body scans.
-
Backscatter X-ray machines: Use very low levels of ionizing radiation and are less commonly used today.
-
Cabinet X-ray machines: Used only for scanning luggage, not people.
Many travelers with implants prefer imaging scanners because they may reduce the likelihood of a pat-down, but additional screening is still possible.
What Happens If You Have a Joint Replacement or Metal Hardware?
If you have a hip replacement, knee replacement, metal plate and screws, rod, or other orthopedic hardware, you may set off the alarm. If this happens:
-
Inform the TSA officer that you have a medical implant and where it is located
-
Be prepared for secondary screening using a handheld metal-detecting wand
-
In some cases, a targeted or private pat-down may be required
Security procedures vary by country and even by airport, but the general protocol is consistent worldwide: identify yourself as having a medical implant and allow additional screening if requested.
What Research Shows About Orthopedic Implants and Airport Delays
A cross-sectional observational study conducted at four international airports in London examined how joint replacements affect airport screening. Among 50 travelers with joint replacements:
-
14% did not trigger airport security alarms
-
Of those who did, more than half experienced delays exceeding 15 minutes
-
Many travelers were asked to visually confirm surgical scars over the implant area
The study highlighted a major issue: lack of consistency in how travelers with orthopedic implants are screened, which can lead to frustration and delays.
Do Implant ID Cards Help?
Although implant identification cards are not universally accepted, the London study found that travelers who presented an implant ID card often experienced faster and more streamlined security checks.
Researchers suggested that a universally recognized implant ID card or future biometrically enhanced ePassports containing medical implant information could greatly improve the travel experience for patients after joint replacement surgery.
Until then, best practices include:
-
Allowing an extra 15–20 minutes at airport security
-
Informing security officers calmly and clearly
-
Being patient and prepared for additional screening
Remember, TSA and security personnel are focused on public safety and follow procedures that may differ by location.
