I would say no, there is no known cure for arthrogryposis. Right now the focus is more on improving movement, function, comfort, and independence rather than curing it. It is also harder to talk about one cure because arthrogryposis is not just one single disease, so different people can have different underlying causes. As for whether a cure is close, I do not think it would be honest to say that yet. There is progress being made in genetics, diagnosis, and treatment, but that is not the same as being close to a cure.
