First off Thank you for your service. I have two Sons serving. prior to an injury in 2007 I have had no knee problems.I had the OATS procedure done May 15, 2009. The pain from surgery was not bad. I was on Tramadol for the first two months (bad stuff). I was in the hospital for 4 days due to the insurance company not approving a CPM for home use. You will need one for 6 weeks. iI started P/T one day after getting out of hospital. I have been to therpy 3 days a week since. My range of motion is great now. It was scary at first. I was unable to move the leg. as hard as I tried it just would not move. I could slide left to right but not able to lift off the bad. It took 2 weeks to be able to lift it off the bed. To this point the worst thing has been non weight bearing on the leg. I am currently using a walker. I was told by the O/S in the begginng it would be 6 weeks non weght bearing. At the end of 6 he said lets give it 3 more. When I saw him last week he said lets give it 3 more weeks. I tried to negociate down and was not sucessful. HE said we need to give it 3 months non weight bearing. In the begining of this he said that the surgery was not hard but the recovery WAS. At this time I agree the recovery sucks. Not the pain but the inability do do things. The TV programs will get old the couch will get lumpy and the wlls will close in on you. They have on me. I keep thinking the summer is gone and I have not been fishing, to the flea markets, yard work, all parts of summer. My goal is to be pain free and be able to do all that this fall. God bless and keep the faith.
