The common pathogenesis is impaired fetal movements. In addition to joint abnormalities, other findings occur with greater frequency in individuals with AMC.

In studying the treatment of arthrogryposis, the main conclusions were that a careful clinical evaluation by a team with experience in arthrogryposis as early as possible is important for correct diagnosis and planning of treatment, and that care should be taken to minimize immobilization in order to avoid further muscle atrophy, especially during early life.
