What NHS sources say about travelling after a knee replacement

Each NHS page as read on 9 Nov 2026 [1] [2] [3]. We found no NHS figure for how soon you can take a short flight after a knee replacement: ask your surgeon.

The reason for the wait is the risk of a blood clot in the leg (DVT). Surgery and a long journey each raise it, and the risk lasts for weeks after the operation [3]. Count the whole journey door to door, including the drive to the airport and the wait at the gate, not just the time in the air.

Can you travel after knee replacement surgery?

Yes, once your surgeon says you are fit to. How long that takes depends on your recovery and the journey. For journeys longer than 4 hours, the Royal Orthopaedic Hospital's advice is to wait 3 months [1]. Tell your surgeon about any trip you are planning, and tell your airline or travel company about your operation: the Royal Orthopaedic Hospital asks patients to do both [1].

How long should you wait before flying after knee surgery?

• Knee replacement, flight over 4 hours: wait 3 months, in the Royal Orthopaedic Hospital's advice [1].
• Any operation, long-haul flight: not within 4 weeks before or after surgery [1]. This covers keyhole knee surgery (arthroscopy) too.
• Shorter flights: we found no NHS figure. Your surgeon decides.

The Royal Orthopaedic Hospital's advice covers hip and knee replacements and does not give a separate figure for a partial knee replacement [1]. For driving, the NHS says to wait at least 6 weeks after a total knee replacement or 3 weeks after a partial one, and to check with your doctor that you are fit to drive [2]. If your surgeon says you are fit to fly, ask them to put it in writing.

Will a knee implant set off airport security?

It might. Tell the security officer about your knee replacement before you go through the scanner, and allow extra time at the airport.

Do you need to declare a knee replacement to your insurer?

Ask your insurer before you book, and get the answer in writing: whether you need to declare the operation, and whether the policy covers you if you develop a blood clot on the trip. Our guide to travel insurance after surgery abroad sets out what to ask.

How to lower the risk of a blood clot on a journey

The Royal Orthopaedic Hospital's advice for long journeys [1]:

• Regularly circle your feet and stretch your legs.
• Take short, regular walks.
• Drink plenty of water and avoid alcohol.
• Avoid restrictive clothing.
• Tell your travel company about your recent surgery.

Keep wearing the compression stockings you were given for as long as you were told to [2]. The NHS says to call 999 or go to A&E if you have symptoms of DVT, such as pain and swelling, and feel short of breath or have chest pain. If you think you have DVT without those, ask for an urgent GP appointment or contact NHS 111 [3].

Tips for comfort while travelling

• Carry your medicines and the letter from your surgeon in your hand luggage.
• Ask the airline for assistance through the airport if you are still using crutches or a stick.
• Book an aisle seat so you can get up and walk.
• Keep your leg raised when you can: the NHS says this reduces swelling [2].
• Arrange your physiotherapy and follow-up appointments at home before you travel.

Considering knee surgery abroad?

If you have the operation abroad, the flight home is part of the plan. The NHS says: "You should stay in the country where you've had treatment for a suitable length of time to recover before travelling home" [4]. Before you book, ask the hospital in writing how long you will need to stay, who decides you are fit to fly, and what follow-up it arranges once you are back in the UK.

Our hip and knee replacement price list shows what hospitals abroad publish, and our guide to knee replacement cost in the UK has the UK prices. For the whole trip, step by step, see knee replacement surgery abroad. Flying after a hip replacement is covered in how long after a hip replacement you can fly.
