xrays/preop

Hello friends, I underwent a TKR back in 2005, and the surgery completely falied. I was also battling RSD/CRPS before and after the operation. I no longer can walk on my left leg and am totally disabled from this.. My question is "is it a Standard of Care to have XRAYS or a MRI done before the Joint Replacement. Would a Surgeon not use films before a major replacemnt?
Thank you, Leonnie
