Glad your recovery is going well. On a more cautionary note, a friend had both knees replaced two years ago - about 5 days after the surgery he fell and badly damaged one knee, had another surgery which used a donor tendon to repair some of the damage, developed a bad infection, another surgery, and ultimately had to amputate the leg above the knee. He is doing well with an artificial leg now, but nowhere near the functionality that he was hoping for with the knee replacements. For anyone else who is planning a knee or hip replacement, make sure you don't fall in the first few weeks after the surgery!
