What is it about?

Robotic-assisted surgery is new technology that can assist surgeons in improving precision and alignment of knee replacements. However, new technology is associated with learning curves. In this study we report that the learning curve of robotic-assisted total knee replacement is short (16 cases on average), and comes with a 12 minute increase in operative time during learning, however no adverse effects on patient outcomes were detected at two-year follow-up.

Why is it important?

There is increased frequency in the introduction of robotic-assistance for surgery globally. The findings from this study is informative for both surgeons and patients in terms of the expectations of surgical and post-surgery outcomes from the introduction of such systems.

Perspectives

Personally I am pleased to report these findings on implementation of robotic-assisted surgery as one of the main questions that knee replacement patients have in terms of new technology is with associated risk. This study clearly defines patient outcomes with introduction of robotic-assisted surgery, and so will be useful in informing patient expecations.
