Why Can You Not Travel by Air Immediately After Knee Replacement Surgery? 

Traveling after knee replacement is prohibited as, at that stage, the knee is still recovering. During this time, the knee bone and surrounding muscles are getting used to the implant. All the tissues and muscles around the knee are weak and healing. Thus, they need proper physical therapy before they are strong enough to support the knee.

Traveling by air or any other mode of transport means keeping the leg down in one position for a long time. It leads to less blood circulation in the legs and around the knees. It is one of the main causes of Deep Vein Thrombosis (DVT).

In this condition, blood clots (thrombus) form in one or more of the deeper veins, usually in the legs. It causes the leg to swell, pain, and become tender. These clots tend to break away. They get lodged in the lung, leading to pulmonary embolism, which could be fatal.

The main reason for DVT occurrence is due to immobility of the body after a knee operation. You need to take extra care during the recovery period. Thus, doctors recommend rest and proper physiotherapy for about 6 weeks before allowing air travel.

  1. Exercises

There are many exercises that you can do while sitting in the aircraft to have proper blood circulation. These exercises include calf squeezes and ankle pumps. Start by doing calf raises where you lift your heels off the floor and contract your calf. Hold it for about 15 seconds and relax. Do this about 10 times and repeat it after every 30 minutes. 

Another helpful exercise is ankle circles, where you lift your foot and make circles with the big toe. You could also rotate the foot clockwise and anticlockwise a few times. One more helpful stretch for the legs is to pull your knees to your chest. These simple movements will go a long way in keeping those muscles relaxed and pain-free.

  1. Compression Stockings

Wear compression stockings while traveling as they will hold your knees in place during long flights. They fit snugly around your knee. Compression stockings exert gentle pressure on the legs that helps boost the blood flow. Thus, they reduce the chances of developing deep vein thrombosis (DVT).

Compression Stockings

These stockings come in a range of sizes and lengths. They are available with different strengths of compression. It is best to ask your surgeon what kind of stockings are best suited for your condition.

  1. Hydration

It is essential to remain hydrated while on the flight. The air-conditioning and the closed environment of the flight can leave you dehydrated. Drink plenty of liquids like water, electrolyte drinks, and fresh juice. Avoid dehydrating beverages like alcohol and coffee.
