Why Choose Us for Kniest Dysplasia Diagnosis and Care


Nemours Children’s Health System has been recognized for delivering advanced pediatric orthopedic care since 1940. Families from all over the world travel to see our skeletal dysplasia experts. Our genetics doctors have the experience and training to diagnose even the rarest types of skeletal dysplasia. Once we’ve identified your child’s condition, we work together to create a personalized treatment plan.

Treatment is led by our world-renowned pediatric orthopedic experts, including Dr. William Mackenzie. Since skeletal dysplasia can evolve and change with time, Nemours has established one of the world’s top pediatric imaging programs to track and measure changes to children’s bodies.

Our care navigators coordinate appointments since most kids need to see different specialists, and some may need multiple surgeries. We also help kids with Kniest dysplasia achieve the highest possible function and quality of life through access to Nemours experts and support services, including:

  • clinical trials research opportunities
  • support services and community resources
