I've been saying this for a long time! You asked me for a name, but that's why I cautioned you to do your homework. You can review every Hospital/clinc/ doctor, etc. and they all state they're the best. One of my very first comments on this forum was titled "It's a crap shoot."
After reading about and listening to the many dissatisfied TKR patients over the years I maintain the reported success rate is overstated. Not one of the many TKR recipients I communicate with, including myself, has ever been surveyed whether they are satisfied with their prosthetic knee(s).
There can be contentious opinions from those that are satisfied with their new knees who state that the only ones complaining are the dissatisfied recipients. My answer is, show me a "fact checked" survey!
