Congratulations....I'm happy for your progress. I want to send a small bit of information your way though, just in case there are any setbacks!
My first week was great, as far as knee flexion and extension, though the pain was pretty high still; then...midway through the 2nd to third week I stopped progressing in my bending and the pain increased. I had been reading through many of the posts on this forum and decided to slow down on my recovery exercises, I had been doing all the elevating and icing and pain medications as prescribed, but the leg went into a holding pattern for about a week and 1/2. By slowing down and listening to the advice here....I started feeling better. Just in case you see a regression, it is just a matter of waiting to heal the knee.
Best of luck, I hope it all goes well for you!
