Note from the Editor

The year 2016 marks Arthroplasty Today's second year of publication with recognition by the National Institutes of Health PubMed Central (PMC) digital archive, publication of research using data from the American Joint Replacement Registry (AJRR) and growth in the number and types of manuscripts published. Modernmedicine is as much about communication as it is about anything else: communication between physicians and patients, authors and readers, communication about unique cases and techniques, original research, and best practices. For communication between doctors, the open access medical journal is a powerful and important tool. Arthroplasty Today is an example of such a journal. Our journal, published by the American Association of Hip and Knee Surgeons (AAHKS), places a high priority on rapid publication and seeks to publish a broad range of content while focusing on the case report. Arthroplasty Today was accepted this year as a PMC journal, and all manuscripts since our inception will be indexed. PMC is the US National Institutes of Health digital archive of biomedical and life sciences journal literature. Since its inception in 2000, PMC has grown to an electronic archive offering free access to more than 3 million full-text journal articles. Arthroplasty Today is the official journal of AJRR and this year marked our first publication of data from AJRR in our June issue. Our current issue again publishes an executive summary of the AJRR Annual Report with a link to the full text of the report on our home page. Once more, our September issue included a worldwide perspective with manuscripts from authors representing 5 different countries and an editorial from Kazuo Hirakawa, MD, PhD, one of our Editorial Board members. Our December theme issue focuses on the complexities of difficult periprosthetic nonunions and pathological fractures. Wayne G. Paprosky, MD, Professor of Orthopaedic Surgery, and Christopher M. Melnic, MD, Adult Reconstructive Hip and Knee Fellow, from Rush University Medical Center will comment.
