I had a tkr in 2009 and ended up in alot of pain. I was told 2 years later by a new doc that the implant wasn't alligned properly and that after testing I was allergic the metal. In 2011 I had another replacement but the doc advised me that he thought if he just replaced part of the knee it would hopefully work. Now a year later my knee is still swollen, cant walk up and down the stairs or do anything without pain. Is there anyone that can offer me any suggestions to help with this problem. Please let me know. ThanksView Thread
