Thanks for the info. I have looked up subluxation and it seems that this is what happened. I'm very worried as everything I read seems to point to error during surgery. My surgeon is very well respected; in fact, my previous orthopaedic surgeon (who is now retired) passed me onto this guy and told me he was the only surgeon that he let operate on his own mother. His waitList was much longer than others and I waited months to be seen by him. I wonder if I've made a terrible mistake?
Since Friday, I've taken things very easy, however, a couple of times when I've walked around the house, I've felt the joint 'drop' again. I'm now so scared that when I'm walking, I'm almost skimming the floor with my foot on my operated side so that it doesn't drop or slip. This cannot be good for my recovery. I know my muscles need to strengthen to hold it in place but any activity I can do to strengthen them seems to put my joint in a vulnerable position.
I will call the hospital tomorrow and see what they advise.
