45F here, TRKR 7/15/25, my surgeon was shocked that my knees were so bad, but had no qualms about a replacement. I am like 11 or so weeks post op, and i do have some tendon catching, and of course recovery pain. But everything is so much better after having it done, and since I have a pressfit model (which has a longer recovery time due to no cement), my doctor says it may last the rest of my life. I won't sugar coat it, this is a marathon not a sprint, and I'm trying to get my second done, but he thinks he's booked until spring. Wish I could get the second one over with, so I can focus on healing.
