Not necessarily, for one leg amputees their running prosthetic is adjusted to match the length of their leg. When it's a double amputee it can be a bit longer (not an amputee but follow a few professional runners who are and talk abt their prosthetics)
Whats very unlikely it's that ML had found a walking and running prosthetic that match the exact type of amputation that MC has
I wonder if any real leg amputees have read this because isn’t a running leg longer than your actual leg so he’d just be walking around wonky all the time? But I guess for apocalypse you can’t complain about what you have
