Hello @riderwayne. I moved your discussion to the Joint Replacements (https://connect.mayoclinic.org/group/joint-replacements/) group and combined it with an existing discussion titled, "Having knee replacement: how to prepare and questions about PT." This discussion is filled with members asking questions about the time leading up to the actual surgery, how to best prepare and how to get the best results after the surgery takes place.

@riderwayne, you mentioned you are nervous about being put under anesthesia. Since you posted the original discussion in the HCM group, are you nervous about being put under because of heart issues?

@riderwayne I too was apprehensive about having a general anesthesia since after my first TKR I was left in a very confused state. My orthopedic surgeon said that was not a problem. Whatever I had it put me to sleep but it did not bother me afterward at all.
As @kajon commented I would discuss either with the anesthesiologist or your orthopedic surgeon. He is really the one who determines what type of anesthesia is used I think unless there are unusual circumstances.
