Knee replacement surgery is a common procedure, but many patients are concerned about whether their new knee will set off airport metal detectors and cause delays or inconvenience when travelling. While newer screening technology has reduced the likelihood of false positives, most sources agree that there is a good chance that knee replacements containing metal will set off airport metal detectors. Patients can inform the TSA agent, fill out a notification card, or go through an X-ray to reduce the likelihood of a pat-down.

Metal knee implants will likely set off airport metal detectors
A 2017 study found that 38% of patients with knee replacements reported triggering a metal detector, while another study from 2022 showed a higher detection rate of 71%. It is important to note that the metal type of your implant may play a role in detection, with cobalt-chromium alloys or titanium being the most commonly detected metals.
To reduce potential inconvenience and prepare for possible travel delays, individuals with metal knee implants are advised to allow extra time at the airport. While the Transportation Security Administration (TSA) does not require patients to carry identification cards for their implants, informing a TSA officer about the presence of a metal implant before screening begins is advisable. Passengers can also utilize the TSA's Notification Card to communicate this information discreetly.
Although disclosing the presence of a metal implant may not exempt passengers from additional screening, it can help protect privacy and reduce the likelihood of a pat-down. If further inspection is required, individuals may be subjected to additional wanding, pat-downs, or requests to present surgical scars or incisions in a private room. Overall, while metal knee implants may set off airport metal detectors, proper communication and preparation can help minimize any potential disruptions during travel.

Inform TSA officers about your knee replacement before screening
Metal implants in the body, including knee replacements, can set off metal detectors during airport security screenings. While this can be embarrassing and time-consuming, it is a common occurrence. It is recommended that you inform TSA officers about your knee replacement before screening.
You can do this verbally, by using a TSA Notification Card, or by providing medical documentation. If you have a card, it is recommended to present it to the TSA agent as soon as you show your ticket and picture ID. This will speed up the process. You can also request a pat-down inspection instead of walking through a metal detector or being hand-wanded. If you are directed to go through a full-body scanner, there are no special precautions you need to take.
If you have a knee replacement, it is likely that you will be issued a card by your healthcare provider. While these cards are helpful, they are not necessary. If you do not have a card, you can ask the TSA officer to be discreet when assisting you through the screening process. You can also request to speak with a supervisor at the checkpoint if you are uncomfortable with the screening process.
It is important to arrive at the airport early to account for any delays that may occur during the screening process. Respond calmly to the TSA officials, as they are just trying to keep you and the other passengers safe.

You may be directed to a screening machine and/or pat-down
If you have had knee replacement surgery, it is likely that airport metal detectors will sense your implant as you walk through the scanner. A 2024 study found that 71% of knee replacements set off the alarm, while another study from 2017 reported a lower detection rate of 38%.
If you have a knee replacement, you are not required to carry an identification card. However, it is advisable to inform the Transportation Security Administration (TSA) officer before screening begins that you have had a knee replacement and to point to the location of the implant. Passengers can also utilize the TSA's Notification Card to communicate discreetly with security officers.
Even with a notification card, a traveler with a knee replacement may still experience some inconvenience and should be prepared for travel delays and extra time at the airport. If the metal alarm is triggered, you may be directed to a screening machine and/or pat-down.
If you prefer to avoid a pat-down, you can opt for an X-ray process, which will provide TSA agents with proof of your implant. The X-ray machines used in airports use very low levels of ionizing radiation, which is perfectly safe.
In general, if you have a knee replacement, it is recommended to allow for extra time when passing through airport security.

Carry a doctor's letter or card with implant details for emergencies
Knee replacement surgery is a common procedure, and its popularity is growing. As a result, the impact of airport security checks on patients who have had knee replacements is far-reaching. Metal implants, including knee replacements, can set off metal detectors during airport security screenings.
While it is not a requirement, it is recommended that individuals with knee replacements carry a doctor's letter or card with implant details. This is not only for emergencies but also to streamline the security process. In the UK, joint replacement surgery has been performed since the 1960s, and the number of procedures has grown exponentially. As such, the potential influence of airport security checks on patients is significant.
A total of 160,000 total hip and knee replacements are performed each year in England and Wales, and the number of joint replacement surgeries is increasing. This means that a large number of active patients who travel frequently may be impacted by airport security checks.
The presentation of implant identification cards can negate the need for more invasive searches, such as strip searches, which can cause unnecessary delays for travellers. Additionally, airport staff can be more efficient as they don't need to be redirected, and replacement staff is not required.
While the Transportation Security Administration (TSA) will accept a medical ID card or other documentation, individuals with knee replacements will still have to undergo screening. It is important to note that a full-body scanner will not damage implantable devices. If an individual's implanted device sets off the metal detector alarm, they will likely be asked to proceed with a secondary screening. This may include a handheld wand inspection, which individuals with heart devices should be cautious of as the magnet inside may interfere with the device.
Overall, carrying a doctor's letter or card with implant details can help streamline the airport security process and reduce the need for more invasive searches, making travel more accessible and efficient for individuals with knee replacements.

Handheld scanners will likely detect all metal implants
Metal implants in the body, including knee replacements, can set off metal detectors during airport security screenings. Handheld metal detectors are often used by security personnel to resolve alarms associated with metal implants.
If you have a metal implant, it is recommended that you inform the security officer about your condition and where the implant is located. You may also be asked to proceed with a secondary screening, which may include a pat-down inspection or the use of a handheld wand.
While medical ID cards are not required, they can be helpful in notifying security personnel about your condition. These cards can be presented during the screening process to maintain privacy and confidentiality.
It is important to note that while full-body scanners will not damage implantable devices, they may still set off the alarm. In such cases, a simple statement of explanation about your condition is usually sufficient, and only a small percentage of patients are asked for documentary evidence of their implant.
