Well folks tomorrow ...
Dan my thoughts and prayers will be with you. You will be fine. An older man in my Sunday School class had his second knee replaced this past winter and he did great. He did his own rehab at home since he already knew what had to be done from his first surgery. Just be careful with those pain meds!!!!
You have been through so much with wls and conquered all you had to do to accomplish success with it so you can do it with the knee surgery.
Blessings to you and Ann. She will need our prayers as well if you are like most men patients
