Had both knees done Brewer, was back to semi light duty at work after 3 weeks each time. Stayed awake and watched the first one on the TV--- pretty interesting. After 5 years don't really notice them anymore. Asked the Dr. after the first one what I could do to hurt the healing process and he said just don't fall down. So you can push up against as much pain as you can handle. I took about 10 100 yard walks every day for the first 2 weeks, up and down the stairs everyday. The one thing I didn't do was mix alcohol and pain pills.
