An uncemented hip effectively has a fracture up against the prosthesis. It does take weeks for the bone to grow into and coalesce onto the prosthesis. Sorry. That's the benefit of the cemented option- the bony repair is complete by end of procedure so you're only allowing for soft tissue healing. The good news is that surgeons tend to offer uncemented to physiologically younger patients, so your surgeon was complimenting you!
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
