If you are planning to travel after knee replacement surgery, hip replacement surgery, or another orthopaedic procedure involving metal implants, you may be wondering whether your implant will set off airport security scanners. As an orthopaedic surgeon in Brisbane, this is one of the most common questions I am asked before patients travel interstate or overseas.
The good news is that travelling with orthopaedic implants is usually straightforward. Understanding how airport security screening works can help make your journey much less stressful.
Can Orthopaedic Implants Set Off Airport Security?
Modern orthopaedic implants are commonly made from titanium, cobalt-chromium alloys, or stainless steel. These materials are selected because they are strong, durable and designed to remain safely within the body for many years.
Larger implants, such as total knee replacements, total hip replacements, and some shoulder replacements, may be detected by airport security scanners. Knee replacements are generally more likely to trigger security systems than hip replacements because they are closer to the skin’s surface. Smaller implants, including plates, screws and ligament fixation devices, are less commonly detected, although this varies depending on the type of implant and the screening equipment used.
Many airports now use advanced body scanners rather than traditional metal detectors. These systems are designed to identify objects or areas that require further assessment. If your implant is detected, it simply means you may undergo a brief secondary screening before proceeding through security.
Do I Need a Letter from My Orthopaedic Surgeon?
Many patients ask whether they should carry a letter from their orthopaedic surgeon or an implant identification card.
In most cases, the answer is no.
Airport security staff follow standard screening procedures regardless of the reason metal has been detected. A surgeon’s letter or implant card will generally not exempt you from additional screening if an alarm is activated.
That said, some patients find it reassuring to carry an implant identification card or a brief summary of their surgery, particularly when travelling internationally. While these documents are not usually required, they may help explain the reason for the implant during conversations with security staff or healthcare providers if needed.
What Happens if My Implant is Detected?
If your implant activates a security scanner, there is no need for concern.
You may be asked to step aside for a routine secondary screening. This commonly involves a handheld metal detector or a brief pat-down of the area identified by the scanner. These procedures are routine and performed every day for travellers with medical implants.
Importantly, you will not be asked to expose your surgical scar or remove your implant-related clothing.
Flying Soon After Orthopaedic Surgery
If you have recently undergone knee replacement, hip replacement, fracture surgery or another orthopaedic procedure, the timing of your flight may be more important than the airport screening itself.
Following surgery, swelling, reduced mobility and the use of walking aids can make navigating an airport more challenging. Longer flights may also increase the risk of deep vein thrombosis (DVT), particularly after lower limb surgery.
Before travelling, it is sensible to discuss:
- when it is appropriate for you to fly after surgery
- whether blood clot prevention is recommended
- the use of compression stockings if appropriate
- strategies to move regularly during long flights
- any restrictions specific to your operation.
If your mobility is limited, arranging wheelchair assistance through your airline before you travel can make moving through large airports considerably easier.
Practical Tips for a Smooth Airport Experience
A little preparation can make travelling with an orthopaedic implant straightforward.
- Allow extra time at the airport in case additional screening is required.
- Wear comfortable clothing that is easy to move in and avoid unnecessary metal accessories where practical.
- Keep any essential medications in your carry-on luggage.
- If you have recently undergone surgery, consider requesting mobility assistance from your airline before you travel.
- Inform security staff if you have an orthopaedic implant if you feel it may assist with the screening process.
Final Thoughts
An orthopaedic implant is designed to help restore mobility and improve quality of life—not to limit your ability to travel. Most people with joint replacements or other orthopaedic implants pass through airport security with little or no delay, and any additional screening is usually brief and routine.
If you are planning travel after orthopaedic surgery and have questions about flying, recovery or your individual circumstances, discussing your travel plans with your orthopaedic surgeon before your trip can help ensure you travel safely and confidently.
