Sounds like you're situation was very specific to OB-GYN, though.
The mindset in ortho (or at least for myself and those I know in the field) is that there is no such thing as a fellow-level case. You get more reps and autonomy in certain cases as a fellow (pelvic trauma, tibia plateaus, arthroplasty revision...), but you should still be prepared to do the case from skin-to-skin as a chief resident, no exceptions. If you're at a solid and well-balanced program, there should be enough volume in these areas to prepare you adequately to do so. At programs with a large amount of fellows, you might have a bit more volume, but you might as well be watching the surgeries on youtube. Maybe it's just an ortho thing, but I'd strongly advise against fellow-heavy programs, and anyone telling you otherwise in this field is selling you snake oil...
