I don't know of anyone else having a TKR in May but I am having a revision in April. Several of us that have had a TKR post under the section titled "TKR March 2005 - Let's keep in touch". That thread started over a year ago when three of us were about to have a TKR around the same time. Since then it has sort of evolved into a TKR support group. (You can see that it has been very popular by the number of posts.) Anyone who is about to have a TKR or who has had one, is welcome to join in. It can be really helpful to have someone to share this with. A TKR takes quite a while to recover from and it is nice to talk to someone who understands exactly what you are struggling with. Another benefit to posting under the "TKR March 2005 - Let's keep in touch" section is that you will get lots of responses. So feel free to start posting there now if you would like.
Is this your first TKR? If yes, then you can get lots of helpful hints prior to surgery. It can take a little while to get to know everyone. Over time we have become friends so we end up sharing more than our TKR.
