I had Arthiscopic Knee Surgery 8 weeks ago...apparently my knee is bone on bone and my therapist doesn't want to touch it because it keeps filling with fluid and swelling up. Last visit to specialist he drained a substantial amount of fluid from my knee and gave be a shot of cortisone. He says that not much can be done once it is bone on bone. What I would like to know from others is that have I given this enough time to recouperate from the Arthiscopic Surgery,,,I am still in a great deal of pain and am having difficulty sleeping, I have yet to drive a car or go back to work as I cannot stand or walk for any great deal of time. Grocery shopping is a nightmare, I have to hang onto the buggy for support and then when home I have to wrap my knee in ice because of the pain and swelling. I think I'm going to need a replacement sooner than later, but how long should I give myself before I don't expect any further improvement from the Arthiscopic Surgery?
