I have watched and peripherally participated in the development of navigated knee replacement over the last 5 years.

After a CT analysis of a number of my cases I became aware of the deficiencies of my instrumented approach.

What I desired was a method that would allow avoidance of rodding the femur. And a way of more accurately reproducing posterior slope.

I am currently using the Articular Surface Mounted system by Stryker with the Triathlon knee system.

I am presenting this as a technique that we are currently evaluating.
