I had 10 weeks of rehab.....but I also had both knees done at same time. Don't rush your rehab....many "warriors " tried the old I don't need no rehab....and screwed the replacement up....not good.I'm sure there are plenty of people on the Board that have had a knee replacement. I'm a reasonably active guy my 50's who has an IT job where I sit at a desk. How long after a knee replacement would I likely be comfortable going back to work. I've seen people taking 3-4 weeks which is way more that I thought. I've had arthroscopic surgery done on both my knees and was only out a day or two. What has been other people's experience?
