Hope your replacement and recovery go smoothly!!!
I had my right hip replaced just over a year ago, was walking on it with just a cane within a week, and without the cane in 3 weeks. Inirial recovery was swift, although had to exercise certain precautions for a while, now have been given the green light for anything, and don't even think about it anymore. Now as far as my left hip is concerned..................
I know knee replacement is more therapy intensive and takes much longer to get thru, so I hope all goes well and ahead of schedule for you!!
