Well folk I am a 66yrs post bilateral TKR of 8 wks and I have to say it was a much bigger op than I thought. Lots of ups and downs, just when you thought you had cracked it you go backwards.Knees can get so stiff I think they will never be right . I tried a water aerobics class yesterday and only managed half an hour!! I did manage to get up and down the five step "ladder" in and out the pool. Things I have learnt so far: Its a much longer recovery than you think,how ever stiff you are, do the exercises, they make it better, when you feel better, don't forget you still cannot pop up and down the stairs. Be patient, life is boring when not at work. Will go back next week I need a focus other than my new knees!! Having said all that I am delighted I had them done!! Good luck to you all!!
