By all accounts, the 23rd meeting of the American Association of Hip and Knee Surgeons (AAHKS) was a great success. There were multiple records established, including 1145 registered attendees, 61 podium presentations, and 150 poster presentations. Bryan D. Springer, M.D. flawlessly chaired the program.
While there were numerous well-designed and well-executed studies, several themes central to both hip and knee reconstruction dominated the meeting. For the hip, 3 areas of emphasis included 1) tribocorrosion related to modularity, 2) infection control and prevention, and 3) the pros and cons of the direct anterior approach (DAA). Multiple investigations analyzed the role of the trunnion in revision total hip arthroplasty (THA), in addition to modular necks in both primary and revision procedures. As always, multiple papers also studied the various methods to diagnosis, prevent, and treat deep periprosthetic infections. Finally, literature surrounding the short- and mid-term clinical outcomes and radiographic results of the DAA compared to conventional approaches were reported.
For the knee, 3 areas highlighted included 1) the economics surrounding total knee arthroplasty (TKA), 2) the impact of obesity, and 3) improved blood management strategies with tranexamic acid. Multiple papers analyzed the inadequate Medicare reimbursement rates, particularly with revision procedures and high-risk patients. Closely related, the impact of obesity on both intraoperative and postoperative complications was emphasized. Finally, the growing body of literature supporting the use of tranexamic acid during TKAs in those patients without a contraindication was apparent.
In all, the 23rd AAHKS meeting displayed the highest caliber of work, resulting in one of the most academically stimulating gatherings. For those interested in joining the organization, additional information can be found at www.aahks.org
