Total ankle replacement with anatomically fitted talar component

A method of attaching a talar component to a talus comprising steps of:

• shaving one or more of articular cartilage, osteophytes, and non-conforming portions of a talar dome to expose bone of the talar dome, wherein the non-conforming portions of the talar dome represent less than 75% of a surface area of the talar component;
• creating one or more recesses in subchondral bone of the talar dome to correspond to one or more protrusions located on a talar surface of the talar component;
• and
• securing the talar surface of the talar component to the talar dome with the protrusions located in the recesses.

A method of forming a talar component of an ankle replacement system comprising steps of:

• obtaining image data of talar dome;
• using the obtained image data to create a three-dimensional model of the talar dome;
• and
• forming a body having a talar surface that approximately or exactly fits with a portion of the surface of the three-dimensional model.
