In reply to pedropierre:
I had mine done at 69 years old, and am now 72
Three pieces of advice i got from the physio
Don't hit the deck, avoid bouldering
Don't swing off a traverse line and crash into a rock face with the replaced joint, the bone round the joint may shatter
Don't lift the repaired limb high and twist it or it is likely to dislocate. Very painfull
For the he first weeks after the op you advised not to cross your legs even when asleep. I wedged a pillow between my legs slept on my back and put pillows either side of me to stop me rolling over. Was back climbing after a few months without problems, just be cautious.
Hope this helps, best wishes for the future
