Thanks. Quick update - I'm exhausted from the long trip (and the darn GPS that decided to take me via the Black Stump (aka the outback)).
Good news - The hip looks firm, no loosening, no signs of any problems with the prosthesis at all -yay! So she's allowed more freedom around the house, no more being locked up, she can get on the couch and bed and play with the cats (not other dogs though).
Bad news is she isn't walking properly. It may be the medial shoulder instability worsening, or it could just be the wasted back leg muscles and poor backwards extension. So she's on leash walks for another month to build up the muscles more and stop her over-stressing the shoulders. Building up to 45min twice a day, plus she can have some restricted off leash time (ie, no chase things).
Anyway this will be fun. Deska can only do 20min so not sure how I'll manage it now we're in winter and the days are shorter. Might be time to make that bush-kart for pushing Deska, anyone mechanically minded out there?
