Supplement to Proceedingsd2016 AAHKS Annual Meeting The year 2016 has been an outstanding year of accomplishment for American Association of Hip and Knee Surgeons (AAHKS). The Annual meeting marked the 26th anniversary and highlighted the remarkable growth, sophistication, and potential impact of our organization. Specific highlights of the 2016 year included a 15% growth in membership, indexing of Arthroplasty Today in PubMed, and the AAHKS contribution of 1.5 million dollars to the Foundation for Arthroplasty Education and Research. The annual meeting continues to grow in size and quality as evidenced by the annual increase in submissions and attendance. The 2016 meeting set new records with 1380 abstract submissions for potential poster and/ or paper presentation. This was the highest number of submissions in our history. Fifty-nine (4%) of these submissions were selected for paper presentation and 200 (14%) were selected for poster display. In addition, we had 10 international poster presentations. There were 40 symposium submissions and 8 were selected for the general session. We had a record attendance at the meeting with all attendees totaling 2802. This represents a 14% growth in attendance compared with the year prior. In addition to the general session, the premeeting courses continue to grow, improve in quality, and attract full attendance. This year, we had 11 industry symposia covering a variety of topics related to hip and knee arthroplasty care. The annual courses also continued to enjoy the tradition of success and excellent attendance. The “Eighth Annual Residents Course” was directed by Matt Austin, MD and Greg Polkowski, MD, and represented a tremendous exposure to the breadth of topics encountered in contemporary hip and knee arthroplasty practice. The Sixth “Annual Team Member Course” was directed by David Dalury, MD and Jason Hurst, MD, and provided a curriculum targeted at the multidisciplinary team of healthcare providers for total joint arthroplasty patients. This course continues to be very attractive and educational for the spectrum of healthcare providers in hip and knee arthroplasty practices. The 2nd Annual course on “The Business of Total Joint Replacement, Surviving and Thriving” was directed by Mark Froimson, MD and Jay Lieberman, MD. This course is directed to the financial and administrative aspects of total joint arthroplasty care and targets physician leaders, business officers, and hospital administrators. As the business aspects of total joint arthroplasty continue to evolve, this course has gained momentum and provides valuable insights regarding alternative payment models, bundled payments, and future evolutions in the delivery of care. As part of our initiative to expand our international relationships, the organization hosted guest societies including the Indian Society of Hip and Knee Surgeons and the European Knee Society. Inclusion of these societies expanded the breadth and dialogue of the meeting and will serve as a foundation for future efforts toward enhanced collaboration 0883-5403/© 2017 Elsevier Inc.

with our international colleagues. Consistent with our tradition of recognizing achievement in the realm of hip and knee arthroplasties, our 2 annual awards were presented for outstanding contributions. Brian McGrory, MD was recognized with the AAHKS Presidential Award for his leadership and accomplishment with the journal Arthroplasty Today. In addition, Brian Parsley, MD was awarded the AAHKS Humanitarian Award for his orthopedic missionary work abroad. The program of the 2016 fall meeting was rich with scientific contributions, symposia, award paper presentations, and the presidential guest speaker Terry Bradshaw. A series of diverse symposia were presented to the membership. This year was noteworthy in that we had an international symposium on hip arthroplasty entitled “Solutions from Across the Pond” in which expert surgeons from the UK presented on alternative surgical strategies related to hip arthroplasty. We also had a co-sponsored symposium entitled “Multimodality Pain Management.” This symposium was cobranded with the American Society of Regional Anesthesia and Pain Medicine and provided a unique perspective and contemporary concepts related to perioperative regional anesthesia. Other symposia covered a variety of topics including hip preservation, alternative payment models, periprosthetic joint infection, challenges in knee revision and soft tissue balancing about the knee. Collectively, these symposia provided contemporary information from experts in our field related to a wide spectrum of timely topics in hip and knee treatments. The selected paper presentations were highlighted by the annual award papers. Joseph T. Patterson, MD and his colleagues from San Francisco, California were awarded the James. A. Rand Award. Their paper was entitled “Administrative Claims vs. Surgical Registry: Data Source and Outcome Disparities in Total Joint Arthroplasty.” This paper highlighted significant differences in the prevalence of comorbidities and incidence of complications in the Medicare/United Healthcare administrative claims data and American College of Surgeons - National Surgical Quality Improvement Program (ACS-NSQIP) data. This work highlights the potential limitations of large database information. The Lawrence D. Dorr Award was presented to David W. Fits, MD and his colleagues from Chicago, Illinois. Their paper explored “Differences in Post-Operative Outcomes between Total Hip Arthroplasty for Fractures vs. Osteoarthritis.” Using the NSQIP data set from 2011-2014, they documented that total hip arthroplasty performed for a diagnosis of fracture is associated with an increased rate of complications, nonehomebound discharge, readmission, and length of stay. These findings support the recent advocacy for exclusion of total hip arthroplasty for fracture from bundled payment programs. The AAHKS Clinical Award was presented to Nicholas Bedard, MD and colleagues from the University of Iowa. He



presented the award paper entitled “What are the Costs of Knee Osteoarthritis in the Year Prior to Total Knee Arthroplasty?.” This study analyzed the cost of nonarthroplasty treatments in the year before total knee arthroplasty and assessed the costs relative to American Academy of Orthopaedic Surgeons clinical practice guideline recommended status. This study underscored the major cost associated with nonsurgical treatment of total knee arthroplasty patients in the year before surgery. Notably, many of these nonsurgical treatment modalities are not recommended by the American Academy of Orthopaedic Surgeons clinical practice guidelines. These findings underscore the major potential for cost savings in the nonsurgical treatment of knee osteoarthritis. Nine scientific sessions composed most of the program. These sessions included scientific papers in various domains of hip and knee disease and arthroplasty care. Sessions included primary hip arthroplasty, primary knee arthroplasty, infection, revision knee arthroplasty, revision hip arthroplasty, complications, nonarthroplasty, and health policy. The program and submissions this year were composed of an increasing number of large database studies. Twenty percent of the paper presentations represented studies analyzing large data sets. The strengths and limitations of these data sets were a major theme of the annual meeting. In addition, 11% of the presentations were from randomized controlled trials indicating a consistent increase in this study design in arthroplasty clinical research. Various other topics were covered by the paper presentations including predictors of patient outcomes, optimization of modifiable risk factors, perioperative patient care, diagnosis of infection, complication management, challenges in revision surgery, surgical approach, and current concepts in joint preservation surgery. An additional highlight of the meeting including our guest speaker and Hall of Fame Quarterback, Terry Bradshaw. The interview-style presentation with Lowry Barnes provided tremendous diversion, humor, and entertainment for the attendees. The success of the annual meeting is certainly the product of a large number of committed individuals who collectively spend an incredible amount of time and effort in creating this outstanding

educational program. It is important to recognize the entire program committee for their efforts in abstract review, abstract and award paper selection, and detailed planning of the annual meeting. We would also like to thank the AAHKS staff lead by Michael Zarski. The success of the meeting would not be possible without the continued efforts and tireless work of AAHKS staff members, including Sigita Wolfe, Eileen Lusk, Sharon Creed, Joshua Kerr, Renalin Malvar-Ledda, Denise Smith-Rodd, and Patty Rose. Their work and efforts are highlighted at the annual meeting, but their dedication and commitment throughout the year is the foundation for the success of our organization. It is also important to recognize our membership. Specifically, those who volunteer for abstract review, publication review, and contribute via attendance at the annual meeting. We also must recognize and congratulate our immediate past AAHKS President, William A. Jiranik, MD, FACS for his commitment and outstanding leadership throughout his presidential year. In addition, we thank the editorial team at the Journal of Arthroplasty including Editor-in-Chief, John J. Callaghan, Emeritus Editor William J. Hozack, Associate Editor J. Bohannon Mason, MD, and Managing Editor Taylor Bowen for their continued support and dedication to efficiently reviewing and publishing papers from the annual meeting. Finally, congratulations to all the presenters and authors whose work was featured at the annual meeting in the form of symposia, paper presentations, poster presentations, and precourse meetings. The orthopedic community and specifically your hip and knee arthroplasty colleagues have benefited tremendously from your time and efforts in improving our field. We hope you enjoy this AAHKS Supplement of the Journal of Arthroplasty as it captures the most important and timely scientific information in our subspecialty field. John C.
