My revision was amazing that over stuffed feeling was gone … I woke up with no pain …. I did have another dr . My original dr said nothing was wrong with knee….when I went for second opinion that dr told me was to big …. I am glad I had it done recovery for me was not to bad …unfortunately I still struggle due to damage and scar tissue having wrong size in there for a year ….. but the revision has given me more flexion …. Can’t say has taken all may pain away or given me 125 like a lot of people but I better than 65 that is where I was before revision …so glad I did revision…hope this helps ….good luck to you
