ASTM WK45235

    New Practice for Cyclic Fatigue Testing of Metal Tibial Tray Components of Unicondylar Knee Joint Replacements

    (What is a Work Item?)

    Developed by Subcommittee: F04.22 | Committee F04 | Contact Staff Manager


    1. Scope

    Scope: 1.1 This practice covers a procedure for the fatigue testing of metallic tibial trays used in partial knee joint replacements. This practice covers the procedures for the performance of fatigue tests on metallic tibial components using a cyclic, constant-amplitude force. It applies to tibial trays which cover either the medial or the lateral plateau of the tibia. This practice may require modifications to accommodate other tibial tray designs. 1.2 This practice is intended to provide useful, consistent, and reproducible information about the fatigue performance of metallic tibial trays with unsupported mid-section of the condyle. 1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.


    The title and scope are in draft form and are under development within this ASTM Committee.
