Metal detectors at airports are designed to identify a wide range of metal objects to ensure passenger safety. This can be stressful for travellers with metal implants, such as hip replacements, who worry about triggering the alarms. While newer screening technology has reduced false positives, hip replacements may increase the time taken to pass through security. A 2012 study found that 84% of patients with hip replacements triggered metal detectors, requiring a handheld wand. However, according to the American Association of Hip and Knee Surgeons, hip replacements are only 31% likely to be detected, while knee replacements are 71% likely. If travellers are concerned about their implants setting off alarms, they can inform TSA agents beforehand and request alternative screening methods, such as advanced imaging, to avoid inconvenience.

What You'll Learn
Hip replacements are usually made of metal
The use of metal in hip replacements has raised concerns about triggering metal detectors at airports. While modern airport detectors can sense most orthopedic implants, a hip replacement is only 31% likely to be detected, according to one source. However, another source mentions that 34% of individuals with hip replacements found it inconvenient for air travel, possibly due to metal detector triggers. A 2012 study found that 84% of patients with hip replacements triggered the metal detector and required a handheld detector for further inspection.
To address these concerns, individuals with hip replacements do not need to carry a card for identification. Instead, they can simply inform a TSA agent about their joint implant containing metal before passing through the scanner. While this may increase the time taken to pass through security, it should not cause significant inconvenience.

Metal detectors at airports are designed to identify metal objects
Indeed, individuals with hip replacements may be worried about setting off metal detectors at airport security. Hip replacements are usually made of metal, and while modern airport detectors can sense most orthopedic implants, there is a chance they may set off the alarm. A 2012 study found that 84% of patients with hip replacements triggered the metal detector and required a handheld detector for further inspection. More recent data from 2017 showed that only 38% of patients with total knee replacements reported triggering the metal detector, while hip replacements were 31% likely to be detected.
If you have a hip replacement and are concerned about setting off the metal detector, there are a few things you can do. Firstly, inform the TSA agent before entering the scanner that you have a metal hip implant. You are not required to carry a card or any form of identification for your hip replacement. Advanced Imaging Technology (AIT) can be used to facilitate your screening and reduce the likelihood of a pat-down. However, if you have a pacemaker or other sensitive internal medical devices, you should not be screened by a walk-through metal detector.
While metal detectors at airports are designed to identify metal objects, they can cause minor inconveniences for travellers with hip replacements or other metal implants. By being prepared and informing the appropriate authorities, travellers with metal implants can alleviate potential stress and ensure a smoother journey through airport security.

Hip replacements can set off metal detectors, but it's not a given
According to Ortho Rhode Island, a 2012 study found that 84% of patients with hip replacements triggered the metal detector and required wanding with a handheld detector. However, more recent data from 2017 evaluating patients with total knee replacements showed that only 38% reported their prosthesis triggered a metal detector. The American Association of Hip and Knee Surgeons notes that knee replacements are more likely to be detected (71%) than hip replacements (31%).
If you have a hip replacement, you are not required to carry a card to identify your implant. However, you should inform the TSA agent prior to walking through the scanner that you have a joint implant containing metal. Advanced Imaging Technology (AIT) can facilitate your screening and reduce the likelihood of a pat-down. It is important to note that you should not be screened by a walk-through metal detector if you have an internal medical device such as a pacemaker.
While the possibility of a hip replacement setting off a metal detector at an airport exists, it is not a guarantee. The sensitivity of metal detectors and advancements in screening technology have reduced the likelihood of false positives. Nevertheless, it is advisable to inform the appropriate authorities and be prepared for additional screening if necessary.

The likelihood of detection depends on the type of replacement
Metal detectors at airports are designed to identify a wide range of metal objects to ensure passenger safety. While newer screening technology has made false positive triggers of the metal detectors less common, it is still likely that a hip prosthesis will increase the time taken to pass through security.
The type of metal used in the hip replacement may also impact the likelihood of detection. Stainless steel, cobalt chrome, and titanium implants are more likely to be detected by metal detectors due to their metallic content.
It is important to note that travelers with hip replacements are not required to carry a card identifying their replacement. However, informing the TSA agent prior to the scan can facilitate the screening process and reduce the likelihood of a pat-down.

Informing TSA agents of your hip replacement can help
It is understandable to be concerned about your hip replacement setting off metal detectors at the airport. While newer screening technology has made false positive triggers of metal detectors less common, it is still likely that a hip prosthesis will increase the amount of time it takes to pass through security. Hip replacements contain metallic components, such as titanium or cobalt, which can set off metal detectors at airport security checkpoints. In fact, a 2012 study found that 84% of patients with hip replacements triggered the metal detector.
- Inform TSA Agents: When you reach the security checkpoint, proactively inform the TSA officers about your hip replacement. Let them know that you have an artificial hip or other metal implant. They are trained to handle such situations and will guide you through the necessary procedures.
- Carry Required Documentation: While not mandatory, it is helpful to carry a joint replacement card or a letter from your orthopedic surgeon as proof of your hip replacement. These cards can be obtained from the Transportation Security Administration (TSA) and allow you to communicate discreetly with security officers.
- Arrive Early: Give yourself plenty of time at the airport. A last-minute rush can increase anxiety and make the security process more stressful. Arriving early allows you to navigate security at a comfortable pace.
- Expect Additional Screening: Be prepared for the possibility of additional screening. This may include the use of a handheld detector or a pat-down. However, you should not need to expose scars or remove clothing during this process.
- Request a Full-Body Scanner: If available at the airport, you can request a full-body scan instead of passing through a metal detector. Full-body scanners can perform a security scan without the risk of your metal replacement joint setting off an alarm.
- Respond Calmly: Remember that TSA officials are there to ensure the safety of all passengers. Respond calmly and cooperatively to their instructions and guidance during the security process.

Frequently asked questions
Maybe. Modern airport detectors sense most orthopedic implants as you walk through the scanner. A 2012 study found that 84% of patients with hip replacements triggered the metal detector. However, a more recent study from 2022 found that hip replacements are only 31% likely to be detected.
Don't panic. The TSA agent may use a hand wand on you, or you may be subject to a pat-down. You can also request a full-body scan if the airport offers both metal detectors and full-body scanners.
No, the TSA does not require patients to carry an identification card for their hip replacement. However, you should let the TSA agent know that you have a metal implant.
Give yourself extra time at the airport to account for any delays. Wear clothes that will enable you to easily provide visual evidence of your surgical scar.
Metal detectors are designed to ensure safety by identifying metallic items. They are extremely sensitive and can detect even small metal objects.
