Request from Dr. Brioschi: "Can anyone identify this cup for sure? It is 20 years old and I am going to revise the stem. I'd like the option to exchange the liner if necessary. Is that an old Zimmer Trilogy? A Stryker Omnifit? Thanks in advance."

Identified by Kevin Brown as an AlloClassic femoral component and a Fitmore acetbular component.
Fawaz H. Jammal agrees that the stem is an AlloClassic but wonders if the cup came from AlloPro. According to the information that we have at https://www.orthopaediclist.com/product/2104151-alloclassic.html, it appears that the AlloPro cup is the same as the Fitmore cup.
Frank R. DiMMaio, MD, MBA indicatrs that he believes it is a Fitmore cup.
Ahmed Nageeb Mahmoud, MD, PhD says that it is a Zimmer Alloclassic Zweymuller stem on a Fitmore cup.
Andrea Fiore, MD says that it is an old Zweymueller stem.
