wherein at least one wing extends out from the body section,

wherein the neck section comprises a plurality of coupling holes that extend into said body section, and

wherein said body section, said neck section, said crown and said wing are made from a single piece of polished metal.

2. A talus implant comprising:

a body section;

a neck section;

a crown positioned at a top portion of the body section;

wherein an outer surface on the body section is formed of a polished metal and configured to interact with cartilage of at least one bone; and

a tibial implant comprising:

a post configured to insert into a tibia of a patient; and

a base plate, configured to interact with the body section of the talus implant.

13. The implant as in claim 12 , wherein at least a portion of the body section has an outer surface that is roughened and formed from a mesh structure.
