EndoLab<sup>\u00ae<\/sup>&nbsp;has developed a simulator that allows either a testing in force control (ISO&nbsp;14243-1) or in displacement control (ISO&nbsp;14243-3). Due to the servohydraulic actuators, excellent machine accuracy has been reached. Please refer the support section to see the simulator moving. Simultaneous testing of three (plus soak control) specimens enables rapid and economic developments. Routine testing is performed using calf serum as a test fluid. In general, the test is stopped after 5 million cycles. Wear is determined by weight loss and\/or geometric measurements.<br><br>To see the simulator moving&nbsp;<a href=\"https:\/\/youtu.be\/OXODzjT0DoU\" target=\"_blank\" rel=\"noreferrer noopener\">watch the video down below&nbsp;<\/a>.<br><br>The wear of the components is determined gravimetrically, particle analysis can be performed. Calf serum with a protein content of 20 g\/l is used for the tests.<\/p>\n\n\n\n<p>This test is often combined with preconditioning according to <a href=\"https:\/\/endolab.org\/de\/mt-polymer-analysis\/astm-f2003-iso-5834-3\/\">ASTM F2003<\/a>, analysis of the wear debris according to <a href=\"https:\/\/endolab.org\/de\/particle-analysis\/iso-17853\/\">ISO 17853<\/a> as well as ion concentration analysis.&nbsp;<\/p>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe title=\"endolab knee simulator ISO 14243 1 and 3\" width=\"800\" height=\"450\" src=\"https:\/\/www.youtube.com\/embed\/OXODzjT0DoU?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe>\n<\/div><\/figure>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe title=\"EndoLab Robotic Weighing\" width=\"800\" height=\"450\" src=\"https:\/\/www.youtube.com\/embed\/Lm_JKN9l0dI?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe>\n<\/div><\/figure>","protected":false},"featured_media":0,"template":"","meta":{"_acf_changed":false,"_uag_custom_page_level_css":""},"class_list":["post-3018","knee-implants","type-knee-implants","status-publish","hentry"],"acf":[],"uagb_featured_image_src":{"full":false,"thumbnail":false,"medium":false,"medium_large":false,"large":false,"1536x1536":false,"2048x2048":false,"trp-custom-language-flag":false},"uagb_author_info":{"display_name":"Kilian Pallauf","author_link":"https:\/\/endolab.org\/de\/author\/"},"uagb_comment_info":0,"uagb_excerpt":"ISO&nbsp;14243-1:&nbsp;Implants for surgery &#8211; Wear of total knee joint prosthesesPart 1: Loading and displacement parameters for wear-testing machines with load control and corresponding environmental conditions for tests.
