Summary of the 3rd international symposium on arthrogryposis.

The 1st international symposium on arthrogryposis (ISA) was held in 2007 in Birmingham, UK, to bring together a multinational group of experts in the field of arthrogryposis, patients and their families to discuss various aspects of care for individuals with Arthrogryposis Multiplex Congenita (AMC). These "lessons learnt" set the tone for the 2nd ISA held in Saint Petersburg, Russia in 2014. Clinical and research advances have recently been made in the field of arthrogryposis and were shared at the 3rd ISA, in Philadelphia, in 2018. Highlights of the 3ISA and future directions are presented.
