The prognosis for arthrogryposis varies from person to person, but the overall outlook is often better than people first fear. It is generally a lifelong, chronic condition, but it is usually non progressive, which means it does not typically keep getting worse just because time passes. Many people will still have lasting joint and muscle limits, but with therapy, splinting, casting, and sometimes surgery, function can improve a lot over time. Most people can go on to live productive, independent lives, and life expectancy is often normal, though that depends on how severe the case is and whether there are major associated problems like serious malformations or other syndromic complications.
