I FINALLY had my consultation with my second OS and I am SO glad I found this guy. He said I might be a good candidate for a partial replacement rather than a total - my first OS (who has been seeing me for two years) has NEVER even mentioned this posibility! My new surgeon says that he will go in and if I have too much damage then he will go ahead and do the TKR at at that time. He warned me that PKRs do not last - they just buy some time - maybe 10-12 years. For those of you with partials, are you happy that you went that route? Have some of you had the partial and then on to the total? Does a partial eliminate the arthritic pain? I have one side full of diseased cartilege and that's where the bones are rubbing and causing me pain when walking beyond about a half a block or even sitting too long. If I abuse it, I pay for it for several days afterwards. He was happy that I had good ROM and that I had been walking up my stairs twice a day! Surgery is scheduled for August 12.
