If its a true axolotl it shouldn't metamorphosize into anything....retains the same form throughout its lifespan. I've had them in the past and nothing as simple as a busted up leg should slow em down much. Young ones have a tendency of taking arms and legs off their tankmates and it doesn't cause permanent harm.
Yeah if it turns into a salamander it will definitely do poorly in a standard aquarium. I've had the benefit of seeing both true axolotls and tiger salamander larvae falsely sold as axolotls...both are very similar when young but tiger salamanders need land. If its gills start going away then you know you have a tiger and not an axolotl.
