We already have examples of this, with some deep meta.
The TV show MASH depicted an army field hospital from the Korean War in the 1950s. They frequently called out specific medical procedures for treating various conditions. One of the main actors was Alan Alda who played a lead surgeon. Many years later, the same actor Alan Alda again played a doctor on the medical drama ER. I remember there was a scene where they needed to treat a specific emergency medical condition and there wasn't the time/materials/whatever to do the modern technique one would use for this. Alda's character suggesting the really old method (that was used as a contemporary technique his character used in MASH). I can't remember if they ended up using it or if they shot down Alda's ER character for the method being out-of-date.
