wow, I somehow missed this thread when I was going thru the diagnosis, but I am another ruptured quad tendon victim. Injury happened on 2/26/2007, surgery on 3/13/2007. The ER doc said it was a strained muscle, but it never got better. I got in for surgery just after the 2-week window they like to operate in.
I don't recall the specifics, but I was out of work for 2 weeks, and I worked from home frequently in the 3 weeks following that. I stopped using the crutches after about 4 weeks and started PT a little over a month post-op. I think I stopped using the brace about 2.5 months out. I'm now at a little over 4 months post-op. Flexsion is very good. I'd say I'm within 10-15 degrees of full ROM, although it's definitely passive and sometimes hurts quite a bit to get that far. I was a little worried about the ROM because I had a couple of very, very sore days. Most of the pain seems to be on the patellar tendon, rather than above the knee. There is still a decent amount of swelling or something going on. My knee definitely does not have the same shape as the other knee. Day to day, things are good. Going down stairs and hills are a bit of a challenge, but I don't need a handrail and I'm fine if I'm careful. I don't think I'm walking with any noticable limp, but there are times when I am noticably cautious.
PT just gave me the OK to start going to the gym and using weights more aggressively. I have been a bit lazy about the strength training side of PT. My wife and I have 6-month old twins (they were 7 weeks old when the injury happened...) and after getting home, eating, spending time with them, getting them to bed, etc., PT is the last thing on my mind. I know I need to start being more disciplined about it, since they will be more mobile soon and I want to continue to ski, hopefully this winter.
So that's my quick story. Now that I found this thread and saw that its pretty active, I'll check back in the future. Good luck, everyone!
