Full title and description

ISO 14243-1:2009/Amd 1:2020 — Implants for surgery — Wear of total knee-joint prostheses — Part 1: Loading and displacement parameters for wear‑testing machines with load control and corresponding environmental conditions for test — Amendment 1. This amendment updates and clarifies parameters and environmental conditions that apply to wear testing of total knee prostheses when tests are performed in machines operating under load control.

Abstract

This short amendment modifies ISO 14243-1:2009 by providing changes and clarifications to the specified loading and displacement parameters, test waveforms and the corresponding environmental/test‑enclosure conditions (for example test temperature and lubricant considerations) used when conducting wear tests of total knee‑joint prostheses on load‑controlled wear‑testing machines. The amendment is published as ISO 14243-1:2009/Amd 1:2020.

Scope

Applies as an amendment to ISO 14243-1:2009 and defines revised or clarified loading and displacement parameters and the corresponding environmental/test conditions to be used when performing wear tests of total knee‑joint prostheses in machines that operate under load control. It is intended to ensure greater repeatability and comparability of laboratory wear results across laboratories and test equipment.

Key topics and requirements

• Updates and clarifications to load‑control test waveforms and peak/valley force values used during knee wear testing.
• Specified displacement/kinematic parameters linked to load‑controlled test rigs (flexion/extension and AP translation relationships as applicable).
• Defined environmental/test conditions (for example test fluid/lubricant and temperature) relevant to wear testing reproducibility.
• Instructions on sample configuration and positioning where these affect load‑controlled test outcomes.
• Requirements for reporting test parameters and conditions so that results are comparable between laboratories.

Typical use and users

Used by biomedical engineers, test laboratories, manufacturers of total knee‑joint prostheses, regulatory bodies and standards committees involved in preclinical wear evaluation of knee implants. The amendment is applied when laboratories perform or specify wear tests on load‑controlled knee simulators to ensure consistency with ISO test practices.

FAQ

Q: What is this standard?

A: It is Amendment 1 (2020) to ISO 14243-1:2009, which updates the Part 1 requirements for loading and displacement parameters and the environmental conditions used for wear testing of total knee‑joint prostheses in load‑controlled machines.

Q: What does it cover?

A: It provides changes and clarifications to the load‑control test parameters (waveforms, forces, kinematics where relevant), specimen configuration and test environment parameters that laboratories must apply when using load‑controlled knee wear simulators.

Q: Who typically uses it?

A: Test laboratories, implant manufacturers, design engineers, regulatory assessors and standards committees concerned with preclinical wear evaluation of knee implants.

Q: Is it current or superseded?

A: This amendment was published in January 2020 and applies to ISO 14243-1:2009. The base standard and its amendments have been the subject of periodic review; ISO records show the base standard was reviewed/confirmed in subsequent reviews (the ISO catalog lists a 2024 confirmation for the 2009 base document). Users should check national/organisational catalogues for the latest consolidated edition or any replacement drafts under development.

Q: Is it part of a series?

A: Yes — it is part of the ISO 14243 series (wear of total knee‑joint prostheses) which includes other parts covering measurement methods (Part 2), displacement‑controlled testing (Part 3) and related amendments. Several parts of the series received amendments in 2020.

Q: What are the key keywords?

A: knee prosthesis, wear, wear testing, load control, loading parameters, displacement parameters, test environment, ISO 14243-1, amendment 2020.
