Knee surgery is often necessary to restore mobility and relieve chronic pain—but it’s not without risks. One of the most serious complications after procedures like total knee replacement or arthroscopic knee surgery is the development of a blood clot, most commonly deep vein thrombosis (DVT). These clots usually form in the deep veins of the legs and can have life-threatening consequences if left untreated.
At Fairbanks Ultrasound, we help patients quickly and painlessly diagnose or rule out blood clots using advanced ultrasound imaging—often the same day you call.
Knee surgery, while beneficial, increases your risk of developing a blood clot for several reasons:
Reduced movement during recovery can slow blood flow in the veins.
Trauma from surgery may damage blood vessels and increase clotting.
Inflammation and tissue repair can contribute to clot formation.
Use of anesthesia and certain medications may increase coagulation.
Knowing this, it’s important to be aware of the early warning signs of a clot so you can get help immediately.
So, what are the signs of a blood clot after knee surgery? Watch closely for the following symptoms—especially in the affected leg:
Noticeable swelling in the calf, knee, or thigh is often one of the first signs. While some swelling is expected after surgery, persistent or increasing swelling may point to a clot.
If you experience sharp, cramping pain or tenderness that feels different from surgical pain—especially when standing or flexing your foot upward—it could be a sign of DVT.
A blood clot can cause the skin over the affected area to turn red, bluish, or pale. These changes are often accompanied by a feeling of warmth or burning.
A clot may cause a warm sensation in one part of the leg, even when the rest of your body feels normal.
If your calf feels tight, firm, or unusually hard to the touch, this may be due to a buildup of blood from a blocked vein.
You should seek immediate medical attention if you:
The gold standard for diagnosing deep vein thrombosis is a Doppler ultrasound—a quick, safe, and non-invasive test that uses sound waves to create images of your veins and blood flow.
