Hi Persia, I had knee replacement about 14 months ago. My knee had bone on bone and I was slowly giving up all the physical activities I enjoyed. I was still lifting weights, doing pilates and riding a stationary bike. I had given up running, Pickleball, rowing. When I had difficulty just going for walks I scheduled the appointment. I was 64 at that time and now I am back to everything but running every day of the week. Try to get the leg as strong as possible before hand and know it takes time to get everything back. I could play pickleball at 4 months but it really was a bit longer before I was running all over the courts and never thinking about my knee. Best of luck to you
