It is a distinct privilege for the Journal of Arthroplasty to be awarded the opportunity to publish the Proceedings of The Knee Society going forward. The Knee Society was founded in 1983, with Chitranjan Ranawat as the first president, for education and research in the area of total knee arthroplasty as well as in the pathogenesis and non-arthroplasty treatment of osteoarthritis and other disease processes that lead to end-stage arthritis of the knee. The goal was to have membership based on a proven ability to perform research, teach, and demonstrate exceptional skills as a clinician and surgeon. The membership currently consists of 206 members, including North American, International, and Emeritus members who are internationally recognized thought-leaders, innovators, mentors, researchers, and educators, and who, as was the vision of the Society founders, are committed to promoting outstanding care to patients who have disorders of the knee through innovation, research, and education. Since its conception, the Society has recognized the need for candid exchange of ideas on implant design and surgical techniques. Hence, annually in the fall, the members convene to present and discuss their most current research in the field of arthritis-related knee surgery. Importantly, the Society recognizes the need and desire to educate the global arthroplasty community on current, data-generated implant design concepts and surgical techniques. Specialty Day at the American Academy of Orthopaedic Surgeons annual meeting has been the forum for this exchange since the inception of the Society. As a highlight of that program, three award papers named in honor of three of the founding members: Drs John Insall, Mark Conventry, and Chitranjan Ranawat are presented. The open call for award worthy research papers, in the previous fall, consistently result in a robust number of high-quality submissions from which to choose these prestigious legacy awards. The published Proceedings of The Knee Society have evolved to a publication of papers from the Fall members meeting and the award papers from the following American Academy of Orthopaedic Surgeons Specialty Day open meeting of the Knee Society which is presently co-sponsored with the American Association of Hip and Knee Surgeons. With the ensuing collaborative partnership between the Journal of Arthroplasty and the Knee Society, the intent will be to produce a robust Proceedings of The Knee Society that archives and memorializes the fall members meeting as well as the outstanding competitive award papers presented at the following annual open meeting of the Knee Society. To publish a meaningful (to the international arthroplasty community [ie, clinicians, researchers, and patients]) Proceedings that truly archives the members’ meeting and publishes the following year’s award papers in a timely manner is a daunting challenge. It can only be done with a truly collaborative relationship and effort with a shared purpose. The production of this Proceedings began with the President of the Society, Robert Trousdale, his Program Chairman and Editor of the Proceedings, Rafael J. Sierra, and the Society staff, led by Olga Foley, committing to, and finalizing a program months in advance and engaging the membership to contribute their work to the Proceedings by the required deadline. Dedicated, experienced, and punctual reviewers from the Society and the Journal of Arthroplasty to assure the requirement for high quality relevant scientific research and an experienced production and Editorial Staff were critical. Regular organized communication among Knee Society and Journal of Arthroplasty staff, editors, reviewers, and authors was paramount. This inaugural Proceedings of The Knee Society in Journal of Arthroplasty is the product of this Knee Society-Journal of Arthroplasty collaboration and team effort intended to provide the most current scientific and innovative work of our Knee Society members to the clinicians, surgeons, researchers, and patients in the arthroplasty community. It is the hope that the Knee Society-Journal of Arthroplasty collaborative product is eagerly anticipated annually by Journal of Arthroplasty readership. The quality of this production would not be possible without grants from two non-profit organizations: AAHKS (American Association of Hip and Knee Surgeons) and OREF (Orthopaedic Research and Education Foundation).
