It was a busy Day One of the annual American Academy of Orthopaedic Surgeons (AAOS) conference in Chicago, and large-joint arthroplasty was the predominant theme.

The talented Jay Lieberman, a AAOS conference regular, moderated an informative and entertaining discussion on the trends in hip and knee arthroplasty in the kickoff symposium at McCormick Place. A spirited talk was held on developments in crafting a definitive treatment algorithm for metal-on-metal (MOM) hip revision. The session also featured a strong debate on the benefits of highly cross-linked polyethylene on metal and ceramic-on-ceramic total hip arthroplasty, with each side making solid points.

A second morning session allowed the brains behind the new American Joint Replacement Registry (AJRR) brag (deservedly so!) about the huge strides they've made in developing a comprehensive and effective national large-joint arthroplasty registry. The presentation underlined the significant gains made in hospital enrollment and changes made to the AJRR's data platform. The potential for this incredibly valuable project has grown by leaps and bounds since its rather lacklustre presentation at AAOS 2012.

Lastly, but certainly not least, Zimmer launched their new Persona total knee system. The launch of this device promises to be one of the largest in company history and signals the start of what many in the industry believe will be "the year of the knee". Stay tuned to this space for more on that topic and other developments as MRG continues its week at AAOS 2013.
