Having had knee replacement why does your foot hurt worse than knee?

It's not typical for the foot to hurt worse than the knee after a knee replacement surgery. There could be a few reasons why you may be experiencing pain in your foot after knee replacement:

1. Iliotibial Band (IT) Syndrome: The IT band is a thick band of tissue that runs from the hip to the knee. It can become tight or inflamed after surgery, causing pain on the outside of the knee and sometimes extending to the foot.

2. Nerve damage: During knee replacement surgery, there's a small risk of damage to nerves around the knee joint. This can lead to pain, tingling, or numbness in the foot and ankle.

3. Scar tissue: After surgery, scar tissue can form around the knee joint. If the scar tissue is excessive, it can put pressure on nerves or blood vessels, leading to pain in the foot.

4. Poor blood circulation: Knee replacement surgery can affect blood circulation in the lower leg and foot. This can cause swelling, pain, and a burning sensation in the foot.

5. Flatfoot: Some individuals develop flatfoot after knee replacement surgery. This happens when the arch of the foot collapses, causing the foot to flatten. Flatfoot can lead to pain in the foot and ankle.

6. Infection: In rare cases, an infection can develop after knee replacement surgery. This can cause pain, swelling, and fever in the knee, foot, or both.

If you are experiencing significant foot pain after knee replacement surgery, it's important to inform your doctor. They will evaluate your condition, identify the cause of the pain, and recommend appropriate treatment. It may involve physical therapy, medication, or further medical intervention, depending on the underlying cause.
