Subject: can one replace broken bones and joints with animal bones instead

I recently saw a project where someone was trying to coat metal with bone like
material to make it more bioactivity and to bond better to the rest of the bone.
I would have thought it easier to just use bones to begin with. I think its the
same material and if cleaned should  not trigger any immune response. So is
there are reason why this cannot be done.
