Abstract

The year 2021 marks the 40th anniversary of the original publication describing the “Endo-model intracondylar rotational” implant, the evolution of the previous St Georg design, now providing two-degree-of-freedom motion and reducing stress on the cementbone interface. A unique condition is that the publication is not reported in bibliometric studies, although its elective indication still exists after four decades. A work deserves the qualification of “classic” not only for the volume of citations but fundamentallyfor the confidence that the application of its content inspires in the long term. Currently all the leading international companies in the implant industry have included in their catalogs their own rotating hinge implants. The scale of comparative constriction is a dilemma and thus a topic for discussion. Currently, the matter has been solved applying inertial sensors technology: the rotating hinge provides less constriction than the condylar constriction implant.
