Why where a dry gauze after knee surgery?

There are several reasons why a dry gauze is placed after knee surgery:

1. To absorb blood and fluid: After knee surgery, there is often some bleeding and fluid build-up in the surgical area. A dry gauze helps to absorb this fluid and prevent it from pooling around the incision, which can help to reduce swelling and promote healing.

2. To protect the wound: A dry gauze helps to protect the surgical incision from infection and from coming into contact with clothing or other objects that may cause irritation or discomfort.

3. To reduce swelling: A dry gauze can help to reduce swelling by applying gentle pressure to the surgical area, which helps to limit fluid build-up.

4. To provide cushioning: A dry gauze can help to provide cushioning and comfort to the surgical area, which can help to reduce pain and discomfort.

5. To facilitate wound healing: A dry gauze helps to create a moist environment around the wound, which is conducive to wound healing.

6. To prevent infection: A dry gauze can help to prevent infection by keeping the surgical area clean and protected from contaminants.
