What surgery? I possess 2 TKRs! No.1 was fine. No problems whatsoever. No.2 was preceded by knee arthroscopy, which IMO was a waste of time, and money. He could have done the TKR straightaway, which also turned out fine. I guess you've already reached the pain threshold, which is the determining factor as to whether you go for a TKR or not! No problems with the surgery; had to stop taking Warfarin for 4 days prior; no problems with that either! Just the usual ones associated with hospital stays; go in with one thing and come out with another; usually cellulitis! Good Health and Good Luck Btw there's a parallel thread running on TKRs
My OH had both knees replaced at the same time 8 years ago. The operation was in the afternoon. Around midnight he went missing. The nurses found him taking a shower! It is a routine operation, extremely successful as long as you do the exercises. Sit around and you might as well not have had it done. The first few weeks after the op. can be trying. Use the pain killers and ice packs and keep in mind the benefits to come. Best wishes.
