Hi, Diane, I am not trying to frighten you, but just to send a word of caution.
A friend of ours just had his 3rd knee replacement surgery. The second one was evidentially the wrong knee type and caused continual pain. Eight years later he went to a maverick type doctor who put in the 3rd knee. Surgery took twice as long, partly because he took out a pound and a half of scar tissue. Most doctors say you can only get up to two replacements in a lifetime and most doctors won't do a third. I've heard of folks in the past have part-replacements to find out later the part was being recalled or that the doctor put in a part because he got a "deal" on it. If your husband has good insurance, please consider getting a second opinion or do an investigation on your doctor through state boards, etc. And yes, I'll say prayers for both of you. Do keep us informed. Take care, Cindy
