@carolamead this is truly terrible! I have not seen the movie but from what you say it is unbelievable that they are doing this. I think if I was about to have a TKR I might rethink if I thought I was a "test". Thankfully I have had two TKRs and both are fine, and they are two different knees with two different surgeons. I do not have quite the flex I would like but I am going to have a minor procedure done to help with that.
I hope that all of you who are having these problems are able to get some relief, somehow. It seems as if a total revision might be the only possible solution. Please keep us posted.
