I don't agree ouch, with all respect. I believe that a significant % of TKRs result in bad outcomes because patient don't do their part and blame the surgeon, hospital, OR staff, etc. - and then come and post here.

I still think this is a small minority of all TKRs. However the vast majority of people with bad outcomes will post on forums like this. Human nature I guess. Reading through this forum over the last 3 years, I see very little evidence of what you claim to see. There are many, many negative reviews of TKRs. I don't doubt you. I just don't see what you're seeing. You wrote "negative reviews are never seen". Not on this forum.
