1. Understanding the Risks of Flying After Knee Surgery

Flying after knee surgery poses specific risks primarily due to prolonged immobility and changes in cabin pressure.

1.1. Increased Risk of Deep Vein Thrombosis (DVT)

One of the primary concerns is the increased risk of Deep Vein Thrombosis (DVT). DVT occurs when a blood clot forms in a deep vein, usually in the leg. Several factors contribute to this risk after knee surgery:

Surgery-Induced Inflammation: The surgical procedure itself causes inflammation, which can increase the likelihood of blood clot formation.
Reduced Mobility: Sitting still for extended periods during a flight reduces blood flow in the legs, making it easier for clots to form.
Dehydration: The dry air in airplane cabins can lead to dehydration, which thickens the blood and further elevates the risk of clotting.
Post-Operative State: Following knee surgery, the body is in a hypercoagulable state, meaning the blood is more prone to clotting.

According to research from the National Institutes of Health (NIH), patients undergoing orthopedic surgeries like knee replacements have a significantly higher risk of DVT in the weeks following the procedure.
