Three months out and my knee is doing really well! I'm able to do most anything I want including kneeling! I'm back running 4-5 times a week, 3 miles at a time, very slow, but its' still running! I still have a long way to go to strengthen the knee and quad, but I'm working hard at it! I've been doing a lot of cycling and that does not bother my knee at all. I go back to the doctor at the end of the month for a checkup. I still can't completely straighten it, although it doesn't seem to bother me as I don't walk with a limp. I will talk to my doctor about it, at one time he said he may put me to sleep and then crank on the knee to break away the scar tissue. We will see.
Have a great day!
