I have knee replacements for both knees now, My question is that the one I had replaced in 2010 is doing well and the recovery time was great but the most recent was in 8-06-2013. on 8-16-2013 they went back into my knee because there were two blood vessels bleeding which in turn filled up my knee cavity and down into the ankle. There has been extreme pain since and is still sore to walk on after 30 minutes or so of being on my feet, my orthopedic surgeon says everything looks good but I don't understand why this surgery is taking so much longer.
