Alignment options in Navigated and Robotic knee replacement- the new generation of accurate alignment execution

Alignment options in knee joint replacements is not a new topic but has regained popularity since the introduction of the anatomical studies related to knee flexion axis documented by Eckhoff D. et al. and new alignment ideas around the so-called kinematic axis disseminated by a few authors such as Howell et al. More recently there has been much interest in the CPAK classification as described by Chen and colleagues in Sydney.

Opponents and proponents of these various knee alignments supposedly ideal for optimal and better functional and long-term outcomes have debated on the subject at the very early stage of modern condylar total knee joint replacement surgery (mechanical vs anatomical axes) and has been revived with the use of the technology in knee replacements.

Over the years, abundant discussions drove orthopaedic companies to design more sophisticated standard TKA instrumentations to address a variety of issues raised by arthroplasty surgeons. Original rudimentary traditional ancillary systems were gradually replaced by advanced tools to tackle evidence-based theories such as gap knee balancing, implant rotation placements or alignment options. However, despite abundant new designs of more complex standard instrumentation with the subsequent increase in number of jigs during surgery, it is apparent that none of them could really beat or even match the most modern computer assisted navigated and robotic assisted technology devices in term of accuracy and precision.

Research has undoubtedly proved the superiority of computer assisted navigated and robotic technology over conventional instrumentation as far as accuracy and precision are concerned and confirmed time and time again that these devices are reliable measurement tools to assess gaps and alignments in knee replacement surgery. Technological enhancements of intraoperative measurements have generated new interest back on alignments on knee replacements. New concepts such as kinematic and restricted kinematic alignments have arisen as well as others and new theories such as individual personalised alignments have been introduced in symbiosis with the growth of robotic systems.

This revalidation session of CAOS UK (Computer Assisted Orthopaedic Surgery UK) will review the current concepts of alignment and balance currently used in modern computer assisted navigated and robotic systems. The panel of experts will go through all prominent systems and will demonstrate how each of them can be used to reach preferential alignment and balance in total knee replacements.

A panel of national and international faculty will demonstrate the pros and cons of each system.

Following the immense success of the previous CAOS UK BOA revalidation sessions, we look forward to seeing you all in Liverpool.
