Oh - you asked about damage - started thinking about the rug and food - got sidetracked!!! LOL
I had a good bit of internal damage - 2 severed tendons and severed quad muscle - had surgery in the Great Falls, MT hospital. They said there was so much swelling, they weren't sure if it would be enough (that I might have to have more surgery later). They even recommended one of the best clinics in the country (Campbell clinic which was near my home in Memphis, TN)....anyway....I didn't need more surgery, BUT I was in a removeable cast/crutches for 9 weeks and was in physical therapy for 3 months (maybe should've gone longer, but got a job). I really had no problems for years until about 2000 when I squatted down to look at something on a low shelf in a store. My knee hurt for months after that. I finally got in to see a surgeon, but the pain was better. He did an MRI anway...there is a torn place under the kneecap that could use repair. He said call him the next time it started to bother me, and he'd get me right in. The next year he moved away!!! I didn't really bother me anymore (at least on a regular basis) until about 4 months ago - now it hurts again quite often. Not bad enough for surgery, though! I'll tough it out. OH - and there is an imprint of a bear tooth on my shin at the bottom of the scar that you can see on the xray and feel!! Freaky!!
