@julesm86, I did NO pt! I would sue anyone who did that to my knee! Your knee has been abused and is swollen, which is making it so tight you can't bend it. So many of us have told you and others that you don't have to go to pt. You will rehab your knee just by living and doing normal things. In the beginning days I did my heels pumps and slides and took care of my cats and myself. That's all. No exercises at all, but just normal living. After about 6 weeks I started rocking by and forth on my recumbent bike. It took probably a week or so before I could do a backward revolution. I did the backward for at least a week before I could do a forward revolution. I'm 3 months out now and do all my normal home and yard duties. I haven't tried riding my outside bike yet, but that will come soon! My suggestion to you is to quit pt and all your exercises. Just live your life. You have to get that swelling down and the only way to do that is to rest it and let it heal.

But what DO you do?
I took the past week off from PT & have been icing & elevating my knee more, and I think it's helping. Saturday I was able to make it all the way around on the exercise bike!!!
And I measured my bend @ 105 (not great yet, but better than 2 weeks ago). I still have issues with swelling & trouble walking normal, but hoping & praying it'll come around & my ROM will improve!!! 
I'm soooo nervous & stressed about going back not being 100% & not back to normal. 
Please keep me (& my knee) in your thots & prayers ~thanks! I did get some compression stockings from my OS, but won't wear them tomorrow~just want to see how the knee does on it's own. I have my ice packs and cane all set to go with me, oh and meds too.
