Title: Symposium on Mobile Bearing Total Knee Replacement Devices
About the Event Papers are invited for a Symposium on Mobile Bearing Total Knee Replacement Devices, to be held Tuesday, May 18, 2010. Sponsored by ASTM Committee F04 on Medical and Surgical Materials and Devices, the symposium will be held at the Renaissance Grand and Suites Hotel in St. Louis, Missouri, in conjunction with the May 18-21 standards development meetings of Committee F04. Mobile bearing knee devices have evolved since they first introduction in the late 1970s with a number of designs now marketed internationally. Designs incorporate a highly conforming surface that disperses contact forces over a large area, potentially reducing wear, and at the same time provides for mobility in the polyethylene bearing to reduce implant to bone interface stresses. Devices include unicompartmental and bi-compartmental knees, with either platform-style or meniscal bearing design of the polyethylene articulating surface. Devices also vary in directional mobility of the polyethylene, type of constraint of the polyethylene, and treatment of the PCL. Mobile bearing knee devices have been classified in the United States as Class III devices because they were not in existence prior to the Medical Device Amendments of the Federal Food, Drug and Cosmetic Act (1976); since there is no existing Class II device to support a Substantial Equivalence determination, they are automatically designated as Class III. Reclassification of mobile bearing knees devices from Class III to Class II is dependent upon, as least in part, the acceptance of FDA recognized special controls that provide for a reasonable assurance of the safety and effectiveness of the device class. The purpose of this Symposium is to compare clinical results from various mobile bearing knee devices with the results from standardized mechanical testing to determine whether standards adequately address real and perceived potential failure modes seen clinically. The goal of the Symposium is to evaluate whether the mechanical testing protocols specified in current and draft ASTM standards are predictive of clinical outcomes and can be used to discriminate between implant designs. This call for papers seeks contributions on the following topics related to current mobile-bearing total knee replacement devices:
To participate in the symposium, presenters/authors must submit online the Abstract Submittal Form and attach a 250-300 word preliminary abstract no later than August 26, 2009. Scroll to the top of the page to "Go to Abstract Submittal Form". To ensure your abstract was received into the ASTM database system, please email hsparks@astm.org stating that your abstract was submitted. The abstract must include a clear definition of the objective and approach of the work discussed, pointing out material that is new, and present sufficient details regarding results. The presentation and manuscript must not be of a commercial nature nor can it have been previously published. Because a limited number of abstracts will be accepted, be sure that the abstract is complete to allow for careful assessment of the paper's suitability for this symposium. Symposium Co-Chairs Kathy Trier and A. Seth Greenwald will notify you in writing by November 1, 2009 of your paper's acceptability for presentation at the symposium. If the preliminary abstract is accepted, the presenter/author will be requested to submit a final camera-ready abstract several months before the symposium. The final abstracts will be distributed in an abstract booklet at the symposium. Symposium presenters are required to submit their papers to the Journal of ASTM International (JAI). JAI is an online, peer-reviewed journal for the international scientific and engineering community. You may access information about JAI at www.astm.org/JAI. Additionally, you may wish to review the new web-based submission and peer-review site at http://jai.peerx-press.org. After the final selection of abstracts has been approved, the ASTM Editorial Office will send authors' instructions via email only. Manuscripts to be peer reviewed for JAI are due online no later than May 18, 2010 at the ASTM Editorial Office. The corresponding author (the author who is the main contact with ASTM Headquarters) will receive a copy of his/her paper in portable document format (PDF). All published authors will have the opportunity to purchase reprints of their papers at a nominal cost. ASTM publishes individual paper(s) in the first available issue(s) of JAI. ASTM also issues a collection of reprinted papers (after publication in JAI) as a Special Technical Publication (STP). (A minimum of ten papers is required for an STP.)
