I am 2.5 months post op from my 2nd knee replacement. The first one was done 6 weeks prior. Dr Illgen at U of Wisconsin did both of mine robotically and so far my recovery is going very well. I really do not like any kind of medication specially pain medication. But I only needed them for 2 weeks after each surgery. I worked at stretching pre surgery to where I could get the back of my knee to lay flat on the floor when I sit. I feel that made a major difference in my recovery on both knee's. I still use the leg straightening board I purchased 2 times a day for 10 minutes. I still have a long way to go but I am very impressed with my results.
