WASHINGTON, D.C. -- Medical breakthroughs are giving new body parts to people with bad ankles. The latest version of artificial ankles is designed to work more like the joint you're born with.
Doctors hope the new parts mean patients will have less pain and more function.
If the newer implants work out, the number of ankle replacement surgeries could take off. More than 200,000 people try to get some sort of treatment for ankle pain every year. There are fewer than 2,500 ankle replacement surgeries per year
