Depending on your character's background and what you're trying to do, there's a few options.
First, you always have the option of not having a replacement at all, or going with a "period-appropriate" replacement like a peg leg or a wooden or steel prosthetic cast in the shape of a leg. If your character isn't particularly well-heeled, this makes perfect sense, particularly for an initial replacement.
Something more than a few RPers have gone with is magitek cybernetics. Thanks to the Alexander story, we now have direct confirmation that these exist, at least in the hands of the goblin Illuminati. That said, since goblin magitek is often derivative of Garlean magitek (which is itself derivative of Allagan technology), it's plausible to me, at least, that a particularly skilled magitek engineer might be able to construct such a limb.
If your character has access to Allagan ruins, it's well-established in the lore that Allagan technology can convert aether into matter, regenerate flesh, clone creatures, and mold "biomass" into a variety of shapes. There's a lot of possibilities here, but it's worth noting that very few people know how to operate such devices, much less where to find exactly the one that would do what you want. This kind of story is most plausible when it involves a long quest or a fortunate accident.
Other possible options that are somewhat less directly supported in lore, but still plausible (IMO), include:
I've never had a character lose a limb in XIV, but I know there a few people who have and can comment more on the effects on their character.

- Regrowing the limb using magic (highly effective regeneration appears in Amdapor)
- Attaching a reanimated limb using magic (we see evidence of reanimated corpses in several places)
- Animating an otherwise mundane prosthetic to act like a limb (Sharlayan can animate all kinds of things)
- Using a simpler clockwork prosthetic that's just strapped on
