A question that comes up regularly in clinic, especially for patients planning travel or interstate visits after surgery: when is it safe to fly after hip replacement?
The main concern with flying is deep vein thrombosis (DVT). Surgery increases the risk of blood clots, and prolonged immobility in a plane cabin compounds that risk. This is why timing matters.
For most patients, I advise:
DOMESTIC FLIGHTS (under 4 hours): typically safe anytime after surgery. We have many patients who fly in from all over Australia, who decide to stay in Adelaide a few days after discharge, and then fly home. This is absolutely fine. You will have blood thinners on board, compression stockings, and you should be walking reasonably well.
LONG-HAUL FLIGHTS (over 4 hours): I recommend waiting a minimum of 4 weeks. At this stage, you are walking well, and the blood clot risk has reduced significantly. It's not quite normal as yet, but the risk is far lower.
Even so, there are sensible precautions:
Book an aisle seat so you can stand and walk every hour without disturbing others. Wear compression stockings for the full duration of the flight. Stay well hydrated and avoid alcohol. Perform the exercises that you were given - especially toe wriggling, ankle pumps etc, regularly, whilst on the flight. And it is recommended to take an Aspirin 100mg before take off, and one on landing as well after longer flights. It will thin the blood slightly, and reduce your risks.
If you have had a blood clot before, avoid long flights for 10-12 weeks post op.
The same principles apply to long car trips and cruises. It is the prolonged sitting, not the altitude, that creates the risk.
If you have a specific trip planned, let me know at your pre-operative or post-operative visit and we can plan around it.
