Fell off my bike, scraped my knee pretty badly?

I fell off my bike and hit my knee. I can't see it but I can feel a small dent on the kneecap. Any ideas?

• HI. I fell off of my bike a couple of weeks ago and hit my knee. It hurt a little the next day, went down to almost nothing the next, and seemed fine on the third, except that there seemed to be a small dent on the knee cap (I can't see it but I can feel it when I touch it - about the size of my fingertip). A week later I went for a run, and the knee got really sore afterward for a couple days. It's back to feeling mostly fine but I still have the dent. I'm hopefully going to the doctor soon, but wanted to know what I should be expecting. Thanks.

• Answer:

  its probably just a bone bruise(bruise in da bone)... dont do that activity 4 2-3 weeks
