My surgeon has spoken with my physiotherapist (who knows my hips best at the moment, and know how badly my deteriorating left hip is affecting my right hip and knee) - and he's bumped me up another category on the waiting list!
So I've gone from a Category 2b (which I gather means "in pain, disabled etc but condition not deteriorating") to Category 2a (in pain, disabled etc but condition is deteriorating). This hopefully means surgery in less than 6 months, although the scheduling isn't up to my surgeon, but the hospital.
So one part of me is saying "Yay!" and another part is saying "Ohshitohshitohshit!" - will be so very good to have it all DONE.
Here's another part of my 'surgery tool kit' - Bio Oil - this was recommended to me by other hip women, as a good way of treating the scars.
Mind you, I've lived with massive scars around the groin and down the side of my left leg nearly all my life - around 130 stitches - not to mention scars from 2 Caesarians (my pelvis is too deformed for babies to get out!) - so I don't know that a new scar will make much difference (and possibly they'll cut along the old main scar anyway). Still, I'll give this stuff a try.
Other advice I've heard about reducing / treating scars from surgery :
Use triple antibiotic ointment on your scar for a year (this will prevent the purple discoloration and visibility) - from a burn nurse.
Moisturiser is as good as any of the (much more expensive) scar preparations - it's the massaging action that is more important - rub it quite firmly to break up the scar tissue underneath - from an orthopedic surgeon.
Vitamin E oil can be good for smaller scars (but THR/PAO scars don't fall into this category!).
Cocoa butter can be good too. It's often marketed as 'stretch mark cream' for pregnant women.
After surgery, eat a good diet with plenty of protein (building blocks for the skin), avoid alcohol (dehydrates you and generally impacts on your health negatively), drink plenty of fluids. And rest, don't push the limits! Your body needs time to heal.
Follow your surgeon's advice on wound care. It probably won't be safe to apply ointments / creams until after the stitches are out / dissolved.
Don't put stress on the incision site by moving / lifting things etc - whatever movement affects the region. Avoid exposure of the scar to sunlight.
Once the wound has healed, firm massage can help even out the bumps or lumps.
About.com has a good article on the subject.
