Will it leave a big scar?

My daughter slipped on a wet road last week and badly injured her knee.

My flesh was completely torn open and I was bleeding so much that I had to get help from others to somehow clean it up and make it home.

Fortunately, the bone was fine, so I only had the wound treated.

It's been over a week now, but only this much has healed so far.

For a while, the discharge was so severe that even when I put on a large Medifoam bandage, it would swell up and fall off within half a day.

So I used Madecassol powder to stop the oozing, but it really just isn't healing.

She is at the age where she has started caring about her appearance, so I am sad because she is so upset.
