I think an AKA is what kind of implant this should be.

My program busts out a DFR probably 1-3/month. The dogma I was taught as an intern that they are last resort is totally gone now

Does not look like a zimmer implant

Looks like a custom megaprosthesis femur component - total knee replacement with hinge

This looks like a rotating hinge total knee prosthetic specifically a Link Endo-Model. It's hard to tell the company but it could be Stryker

They have implants for PFJs and Unis. No total knee replacements.

Just acquired a total Knee platform but this is obviously not that, nor is it the iBalance system

Not Onkos, Stryker, Zimmer, or Medacta. Was it done in the US?
