After 4 prior surgeries, had both done in 2017, and they're great now. PT is tough, and painful, but bust your asss through it and you'll be good to go. Took a couple of months to get most of my range of motion back, and full recovered after about 8 months. It can take up to a year though they say. Nevertheless you'll never get back to full range of motion that natural knee joints gave you.
